+
+ * dmidecode.c: Assume that the max power capacity is expressed in
+ Watts, not milliWatts (DMI type 39). The specification isn't
+ clear about the actual unit, but the only implementation I've
+ seen (HP Proliant G7) clearly uses Watts. Also, using milliWatts
+ would limit the max value that can be stored to 32 W, which
+ doesn't make much sense.

+ * dmidecode.c: Decode BIOS language information flags
+ (DMI type 13).

+ * dmidecode.c: Update two CPU flag descriptions (FXSR and HTT).
+ Drop CPU flag IA64.
+ * dmidecode.c: Update the list of processors for which we decode the
+ CPUID flags.
+
+2010-10-11 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: One more SMBIOS version fix-up case.

+
+ Update to support SMBIOS specification version 2.6.1.
+
+ * dmidecode.c: Add processor types "Dual-Core Xeon 5200",

+ * dmidecode.c: Add memory device types "DDR3" and "FB-DIMM"
+ (DMI type 17).
+ * dmidecode.c: Add cache associativity types "12-way Set-associative",
+ "24-way Set-associative", "32-way Set-associative",
+ "48-way Set-associative" and "64-way Set-associative" (DMI type 7).
+
+2009-07-27 Jean Delvare <khali@linux-fr.org>
+
+ * dmioem.c: Recognize "Hewlett-Packard" as a possible DMI vendor
+ string for HP. Orginal patch from Thomas Hiller (HP).

+ (DMI type 4).
+
+2009-06-19 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Fix decoding of memory array capacity. A maximum
+ capacity of 128 GB would erroneously be reported as Unknown,
+ while a unknown capacity would be erroneously reported as 2048
+ GB. Bug reported by Lin Li (HP).
+
+2009-04-30 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Warn if decoding an SMBIOS implementation which is
+ newer than what we support.
+
+2009-04-04 Jean Delvare <khali@linux-fr.org>
+
+ * Makefile: Clarify license.
+
+2008-11-23 Jean Delvare <khali@linux-fr.org>
+
+ * biosdecode.c: Stop using the inline keyword. It causes more
+ portability issues than is worth given how little we care about
+ performance in this tool, and recent versions of gcc know when
+ to inline functions anyway.
+ * version.h: Set version to 2.10.
+
+2008-11-14 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Handle chassis information records of size 19
+ (DMI type 3).
+
+2008-11-10 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Claim to support revision 32 of Intel AP-485
+ (CPUID). No relevant change since revision 31.
+ * dmidecode.c: Update reference to AMD CPUID document.
+
+2008-11-09 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Decode the CPUID of more Intel, VIA and AMD
+ processors (DMI type 4).
+ * dmidecode.c: More CPUID exceptions based on the version string
+ (DMI type 4).
+ * README: Drop reference to the Linux kernel.
+ * README: Drop "model-specific issues" common problem entry, it is
+ no longer relevant.
+ * README: Simplify "IA-64" common problem entry, most of the
+ issues are solved by now.
+
+2008-11-08 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Add many processor types taken from the CIM Schema.
+ * dmidecode.c: Drop all references to the DMTF Master MIF
+ document. This document hasn't been updated in years, so the
+ additions it may contain are no longer relevant.
+
+2008-11-07 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Handle base board information records of size 9
+ (DMI type 2).
+ * dmidecode.c: Don't display access time equivalent of memory
+ device speed (DMI type 17). The access time didn't add much
+ value, and rounding effects made it look bad at times.
+
+2008-11-07 Jean Delvare <khali@linux-fr.org>
+
+ Update to support SMBIOS specification version 2.6, fourth round.
+
+ * dmidecode.c: Initial support for additional information entries
+ (DMI type 40). Proper support of this new entry type would
+ require redesigning a large part of the code, so I am waiting
+ to see actual implementations of it to decide whether it's worth
+ the effort.
+ * dmidecode.c, dmidecode.8: Update reference SMBIOS document.
+ * dmiopt.c, dmidecode.8: Include entry type 41 in --type baseboard.
+
+2008-11-05 Jean Delvare <khali@linux-fr.org>
+
+ Update to support SMBIOS specification version 2.6, third round.
+
+ * dmidecode.c: Decode the group number, bus number and
+ device/function number of system slots (DMI type 9).
+ Based on a preliminary patch by Matt Domsch.
+ * dmidecode.c: Decode onboard devices extended information
+ entries (DMI type 41). Based on a preliminary patch by Matt
+ Domsch.
+ * dmidecode.c: Add slot types "PCI Express x1", "PCI Express x2",
+ "PCI Express x4", "PCI Express x8" and "PCI Express x16"
+ (DMI type 9).
+ * dmidecode.c: Decode the memory device rank (DMI type 17).
+
+2008-11-02 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Use binary search for dmi_processor_family, it's
+ faster than linear search (DMI type 4).
+ * dmidecode.c: Decode boot integrity services entry point entries
+ (DMI type 31).
+
+2008-10-31 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: The compiler knows how to reuse strings, it doesn't
+ need our help, and actually it does a better job without it. So,
+ turn out_of_spec into a define.
+ * dmidecode.c: Optimize functions dmi_processor_status(),
+ dmi_cache_location(), dmi_system_reset_boot_option() and
+ dmi_ipmi_register_spacing().
+
+2008-10-30 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c, dmiopt.c, dmidecode.8: Option --dump is only a
+ modifier as --quiet is, so it's not actually mutually exclusive
+ with the output format options.
+ * dmidecode.c: Make options --dump-bin and --quiet work together.
+ * dmidecode.c: Delay string filtering when option --dump is used.
+ * dmidecode.c: Refactor dmi_processor_family function to avoid
+ code duplication.
+ * dmidecode.c: Fix up invalid SMBIOS version 2.51.
+
+2008-10-29 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Handle special case of processor family code 0xBE,
+ which can be both Core 2 or K7. We use the processor
+ manufacturer string as a hint (DMI type 4).
+
+2008-10-28 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c, dmidecode.h, dmiopt.c, dmiopt.h: Don't use function
+ pointers for special string cases. Each special case is itself
+ special and needs to call a function with its own prototype, so
+ better have dedicated code to handle it all.
+ * dmidecode.c, dmidecode.h, dmioem.c, dmioem.h: Mark a few
+ pointers const.
+ * dmidecode.c, util.c, util.h: When dumping the DMI table to a
+ binary file, truncate the file first.
+ * dmidecode.c: Support Processor Family 2 field also when queried
+ with option --string.
+
+2008-10-27 Jean Delvare <khali@linux-fr.org>
+
+ Update to support SMBIOS specification version 2.6, second round.
+
+ * dmidecode.c: Add support for Processor Family 2 field
+ (DMI type 4).
+ * dmidecode.c: Add processor types "Turion 64 X2", "Core Solo",
+ "Core 2 Duo", "ESA/390 G6", "z/Architectur", "C7-M", "C7-D",
+ "C7" and "Eden" (DMI type 4).
+ * dmidecode.c: Fix typo in processor type "AMD29000" (DMI type 4).
+ * dmidecode.c: Add processor upgrade types "Socket S1",
+ "Socket AM2" and "Socket F (1207)" (DMI type 4).
+
+2008-10-26 Jean Delvare <khali@linux-fr.org>
+
+ Update to support SMBIOS specification version 2.6, first round.
+
+ * dmidecode.c: Byte-swap the first 3 fields of the UUID
+ (DMI type 1).
+ * dmidecode.c: Add chassis types "Blade" and "Blade Enclosure"
+ (DMI type 3).
+
+2008-10-26 Jean Delvare <khali@linux-fr.org>
+
+ * dmiopt.c, dmidecode.8: Simplify the handling and documentation
+ of mutually exclusive output format options.
+ * dmidecode.8: Document the binary dump file format.
+ * dmidecode.c: Don't display the source dump file name in quiet
+ mode.
+ * biosdecode.c, dmidecode.c, dmioem.c, dmiopt.c, dmiopt.h,
+ ownership.c, types.h, util.c, vpddecode.c, vpdopt.c, vpdopt.h:
+ Mass coding-style change: add spaces around operators.
+ * vpddecode.c: Fix --quiet option.
+ * dmidecode.h, dmiopt.h: Pass version information to print
+ callback functions.
+ * dmidecode.c: Fix up invalid SMBIOS version.
+ * dmidecode.c: Handle base board information records of size 10
+ (DMI type 2).
+
+2008-10-25 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Limit indentation in smbios_decode and
+ legacy_decode.
+ * dmidecode.c, dmiopt.c: Write binary dump to a compact file
+ rather than a sparse file.
+ * dmidecode.c, dmiopt.c, dmiopt.h: New option --from-dump, read
+ the DMI data from a binary file.
+ * dmidecode.8: Update the option --dump-bin, document the new
+ option --from-dump.
+
+2008-08-28 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Add missing colon to temperature probe label.
+ Patch from Alex Iribarren.
+
+2008-02-16 Jean Delvare <khali@linux-fr.org>
+
+ * util.c, util.h: New helper function write_dump.
+ * dmidecode.c, dmiopt.c, dmiopt.h: New option --dump-bin, dump
+ the DMI data to a sparse binary file.
+ * dmidecode.8: Document the new option --dump-bin.
+ * Makefile, biosdecode.c, dmidecode.c, dmidecode.h, dmioem.c,
+ dmioem.h, dmiopt.c, dmiopt.h, ownership.c, util.c, util.h,
+ vpddecode.c, vpdopt.c, vpdopt.h: Update copyright statements.
+ * dmidecode.c: Adjust the error message which is displayed when
+ the table is unreachable.
+
+2007-06-30 Jean Delvare <khali@linux-fr.org>
+
+ * config.h: Add support for Solaris (x86 only, of course). Based
+ on a patch by Sun's Dan Mick, brought to my knowledge by
+ Attila Nagy.
+
+2007-06-27 Jean Delvare <khali@linux-fr.org>
+
+ * Makefile: Fix the uninstall-man target.
+
+2007-06-07 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: If the SMBIOS entry point decoding fails (for
+ example due to a bad checksum), still try decoding the
+ encapsulated DMI entry point. Suggested by Luke Suchocki.
+ * dmidecode.c: Replace all occurrences of "KB" by the more
+ correct "kB".
+
+2007-03-16 Jean Delvare <khali@linux-fr.org>
+
+ * vpddecode.c: Stop asking the user to report bad checksums,
+ unaligned records and the like. Such machines exist, too bad,
+ we have to live with it.
+
+2007-02-27 Jean Delvare <khali@linux-fr.org>
+
+ * biosdecode.c: Fix a compilation error with non-C99 compilers.
+ Patch from Francois Revol.
+
+2007-02-26 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Fix an array overrun while decoding the system
+ event log status (DMI type 15).
+ * biosdecode.c: Use printf instead of fwrite.
+ * dmidecode.8: Some OEM-specific types can be decoded now.
+ * biosdecode.8: List the FJKEYINF entry point type.
+ * vpddecode.8: The product name is no longer displayed.
+ * version.h: Set version to 2.9.
+
+2007-02-16 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Do not print the BIOS base address and runtime size
+ if the base address is 0. This happens on IA-64 because there's
+ no BIOS.
+ * Makefile, README: Do not build biosdecode, ownership and
+ vpddecode on IA-64, as IA-64 systems have no BIOS. This was
+ quite tricky to keep both GNU make and BSD make happy, but it
+ seems that I finally succeeded.
+
+2007-02-13 Jean Delvare <khali@linux-fr.org>
+
+ Update to support SMBIOS specification version 2.5, second round.
+
+ * dmidecode.c: Decode new processor characteristics (multi-core,
+ multi-thread, 64-bit) (DMI type 4).
+ * dmidecode.c: Decode slot ID of AGP 8x and PCI Express slots (DMI
+ type 9).
+
+ * dmidecode.c: Fix the mask of 3 bitfield tests. This will let
+ the memory type of some systems be properly reported as SDRAM.
+ * dmidecode.c: Fix the AMD processors signature decoding.
+ * README: Minor edits.
+
+2007-02-12 Jens Elkner <elkner@linofee.org>
+
+ Update to support SMBIOS specification version 2.5, first round.
+
+ * dmidecode.c: Add chassis types "CompactPCI" and "AdvancedTCA"
+ (DMI type 3).
+ * dmidecode.c: Add processor types "Turion 64",
+ "Dual-Core Opteron", "Athlon 64 X2", "Celeron D", "Pentium D"
+ and "Pentium EE" (DMI type 4).
+ * dmidecode.c: Add processor upgrade types "Socket mPGA604",
+ "Socket LGA771" and "Socket LGA775" (DMI type 4).
+ * dmidecode.c: Add connector type "SAS/SATA Plug Receptacle" and
+ port types "SATA" and "SAS" (DMI type 8).
+ * dmidecode.c: Add on-board device types "PATA Controller",
+ "SATA Controller" and "SAS Controller" (DMI type 10).
+ * dmidecode.c: Add memory device form factor "FB-DIMM" and memory
+ device type "DDR2 FB-DIMM" (DMI type 17).
+
+2007-02-12 Jean Delvare <khali@linux-fr.org>
+
+ * dmioem.c: Share the code between HP-specific types 209 and 221.
+ Both types are really the same, only the title is different.
+ * dmioem.c: Make the HP-specific types 209 and 221 output a bit
+ more verbose.
+ * dmidecode.c: Let --type decode OEM-specific entries when
+ possible.
+ * dmidecode.c: Include decoded OEM-specific entries in quiet mode
+ output (--quiet).
+ * dmidecode.c: Do not complain about truncated entries in quiet
+ mode.
+ * dmioem.c: Decode HP-specific type 204 entries in a safer way:
+ check the length before decoding, and don't assume that all
+ strings are provided in the same order as they are used.
+
+ Update to support Intel AP-485 (CPUID) revision 31 (was 28).
+
+ * dmidecode.c: New CPUID flag IA64.
+ * dmidecode.c: Fix the decoding of Intel extended family.
+
+2007-02-11 Jean Delvare <khali@linux-fr.org>
+
+ * dmioem.c, dmioem.h: New.
+ * Makefile, dmidecode.c, dmidecode.h, dmioem.c, dmioem.h: Move the
+ decoding of OEM-specific entries to a separate source file.
+ * dmidecode.c: DMI type 38 is tested by now.
+ * dmioem.c: The PCI function is typically represented as a single
+ digit.
+ * Makefile, dmiopt.c, vpdopt.c, util.h: Define an ARRAY_SIZE macro
+ which computes the size of a static array, and use it where
+ relevant.
+
+2007-02-11 John Cagle <jcagle@kernel.org>
+
+ * dmidecode.c: Add support for 3 HP-specific entries: system/rack
+ locator (type 204), NIC MAC information (type 209) and NIC iSCSI
+ MAC information (type 221).
+
+2007-01-14 Jean Delvare <khali@linux-fr.org>
+
+ * vpddecode.c: Fix a rare warning.
+ * biosdecode.c: Add support for the FJKEYINF entry point, which
+ contains data related to the "application panel" on Fujitsu
+ laptops.
+
+2006-05-23 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Fix a recently introduced compilation error with
+ non-C99 compilers.
+ * dmidecode.c: Check for short entries (less than 4 bytes), stop
+ with an error when one is encountered.
+
+2006-05-13 Jean Delvare <khali@linux-fr.org>
+
+ * vpddecode.c, README: Drop the product name lookup table. It
+ was reported to be unreliable too many times, and was also
+ difficult to maintain.
+
+2006-05-10 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Don't cast from u8* to dmi_header*, else
+ architectures which do not support unaligned memory accesses
+ may break. Instead, copy the members individually. That's a
+ bit slower, but that's also safer and we only need to do it
+ once per DMI entry, so it's not time critical. So far, we
+ were using a trick to later work around the unaligned memory
+ access, but the compiler would still warn about the risk,
+ which is always confusing.
+ * config.h, types.h, README: Automatically enable the unaligned
+ memory access workaround on ia64.
+ * types.h: Inline U64. It makes sense per se and also lets us
+ get rid of a warning about U64 being unused.
+ * dmidecode.c: Detect EFI at run-time rather than compilation-
+ time. Based on an original patch from Matthew Garrett. This
+ will make x86 binaries work for both PC systems with BIOS and
+ Macintosh systems with EFI. Also prevent a possible, though
+ unlikely, NULL-pointer dereference in the EFI code.
+
+2006-02-25 Jean Delvare <khali@linux-fr.org>
+
+ * dmidecode.c: Fix typo reported by David Wilson (DMI case 3).
+
+2006-02-04 Jean Delvare <khali@linux-fr.org>
+
+ * vpddecode.c: Update lookup table from revision 2006-01-31 of IBM
+ reference document (add product ID "7B").
+ * version.h: Set version to 2.8.
+
+2006-01-21 Jean Delvare <khali@linux-fr.org>
+
+ * vpddecode.c: The mysterious last character of xSeries records
+ may be a BIOS revision. Display it as such when present and
+ non zero, and ask users to report.
+ * vpddecode.c: Adjust an error message.
+ * dmidecode.8: Update the sample entry to match the new output
+ format.
+ * README: Improve the IA-64 specific section and the vpddecode
+ tool description.
+ * vpdopt.h: Add missing system header file include.
+
+2006-01-20 Jean Delvare <khali@linux-fr.org>
+
+ * vpddecode.c: Assume a constant length of 12 characters for the
+ "Default Flash Image File Name" entry. The 13th character never
+ contained anything useful, so it probably has a different
+ meaning (unknown for now).
+

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

+** INTRODUCTION **
+
+Dmidecode reports information about your system's hardware as described in
+your system BIOS according to the SMBIOS/DMI standard. This information
+typically includes system manufacturer, model name, serial number, BIOS
+version, asset tag as well as a lot of other details of varying level of
+interest and reliability depending on the manufacturer. This will often
+include usage status for the CPU sockets, expansion slots (e.g. AGP, PCI,
+ISA) and memory module slots, and the list of I/O ports (e.g. serial,
+parallel, USB).
+
+DMI data can be used to enable or disable specific portions of kernel code
+depending on the specific hardware. Thus, one use of dmidecode is for kernel
+developers to detect system "signatures" and add them to the kernel source
+code when needed.
+
+Beware that DMI data have proven to be too unreliable to be blindly trusted.
+Dmidecode does not scan your hardware, it only reports what the BIOS told it
+to.
+
+
+** INSTALLATION **
+
+The home web page for dmidecode is hosted on Savannah:
+ http://www.nongnu.org/dmidecode/
+You will find the latest version (including CVS) there, as well as fresh news
+and other interesting material, such as a list of related projects and
+articles.
+
+This program was first written for Linux, and has since been reported to work
+on FreeBSD, NetBSD, OpenBSD, BeOS, Cygwin and Solaris as well.
+
+There's no configure script, so simply run "make" to build dmidecode, and
+"make install" to install it. You also can use "make uninstall" to remove
+all the files you installed. By default, files are installed in /usr/local
+but you can change this behavior by editing the Makefile file and setting
+prefix to wherever you want. You may change the C compiler and the
+compilation flags as well.
+
+Optionally, you can run "make strip" prior to "make install" if you want
+smaller binaries. However, be aware that this will prevent any further
+attempt to debug the programs.
+
+Two parameters can be set in the Makefile file to make dmidecode work on
+non-i386 systems. They should be used if your system uses the big endian
+byte ordering (Motorola) or doesn't support unaligned memory accesses,
+respectively. For example, compiling for a SPARC processor would require
+both (but I am not aware of SPARC-based systems implementing SMBIOS).
+Compiling for an IA64 processor requires the memory alignment workaround,
+and it is enabled automatically.
+
+
+** DOCUMENTATION **
+
+Each tool has a manual page, found in the "man" subdirectory. Manual pages
+are installed by "make install". See these manual pages for command line
+interface details and tool specific information.
+
+For an history of the changes made to dmidecode, see the CHANGELOG file.
+
+If you need help, your best chances are to visit the web page (see the
+INSTALLATION section above) or to get in touch with the developers directly.
+Have a look at the AUTHORS file and contact one of the maintainers.
+
+If you want to help with the development of dmidecode, please consider
+joining the dmidecode-devel discussion list:
+ http://lists.nongnu.org/mailman/listinfo/dmidecode-devel
+
+
+** COMMON PROBLEMS **
+
+IA-64
+
+Non-Linux systems are not yet supported.
+
+MMAP
+
+Note that mmap() is now used by default wherever possible, since this seems
+to solve a number of problems. This default behavior can be changed in
+config.h. Just to make sure this is clear, mmap() is not used for performance
+reasons but to increase the number of systems on which dmidecode can be
+successfully run.
+
+CYGWIN
+
+Dmidecode was reported to work under Cygwin. It seems that /dev/mem doesn't
+work properly before version 1.5.10 though, so you will need to use at least
+this version.
+
+
+** MISCELLANEOUS TOOLS **
+
+Three other tools come along with dmidecode: biosdecode, ownership and
+vpddecode. These tools are only useful on systems with a BIOS, so they
+are not built on IA-64 by default.
+
+BIOSDECODE
+
+This one prints all BIOS related information it can find in /dev/mem.
+It used to be part of dmidecode itself, but as dmidecode was growing,
+we felt that the non-DMI part had to be moved to a separate tool.
+
+OWNERSHIP
+
+This tool was written on a request by Luc Van de Velde for use with Novell
+tools in his company. It retrieves the "ownership tag" that can be set on
+most Compaq computers. Since it uses the same mechanisms dmidecode and
+biosdecode use, and could be of some use for other people as well, we
+decided to make it part of the project.
+
+VPDDECODE
+
+This tool prints the contents of the "vital product data" structure as
+found in most IBM and Lenovo computers. It used to have a lookup table
+for the machine name, but it was unreliable and hard to maintain so it
+was ultimately dropped. It has a command line interface.

+.SH NAME
+dmidecode \- \s-1DMI\s0 table decoder
+.SH SYNOPSIS
+.B dmidecode
+.RB [ OPTIONS ]
+
+.SH DESCRIPTION
+.B dmidecode
+is a tool for dumping a computer's \s-1DMI\s0 (some say \s-1SMBIOS\s0) table
+contents in a human-readable format. This table contains a description of the
+system's hardware components, as well as other useful pieces of information
+such as serial numbers and \s-1BIOS\s0 revision. Thanks to this table, you can
+retrieve this information without having to probe for the actual hardware.
+While this is a good point in terms of report speed and safeness, this also
+makes the presented information possibly unreliable.
+
+The \s-1DMI\s0 table doesn't only describe what the system is currently made
+of, it also can report the possible evolutions (such as the fastest supported
+\s-1CPU\s0 or the maximal amount of memory supported).
+
+\s-1SMBIOS\s0 stands for System Management \s-1BIOS\s0, while \s-1DMI\s0
+stands for Desktop Management Interface. Both standards are tightly related
+and developed by the \s-1DMTF\s0 (Desktop Management Task Force).
+
+As you run it,
+.B dmidecode
+will try to locate the \s-1DMI\s0 table. If it succeeds, it will then parse
+this table and display a list of records like this one:
+
+Handle 0x0002, DMI type 2, 8 bytes.
+Base Board Information
+ Manufacturer: Intel
+ Product Name: C440GX+
+ Version: 727281-001
+ Serial Number: INCY92700942
+
+Each record has:
+.IP \(bu "\w'\(bu'u+1n"
+A handle. This is a unique identifier, which allows records to
+reference each other. For example, processor records usually reference
+cache memory records using their handles.
+.IP \(bu
+A type. The \s-1SMBIOS\s0 specification defines different types of elements
+a computer can be made of. In this example, the type is 2, which
+means that the record contains "Base Board Information".
+.IP \(bu
+A size. Each record has a 4-byte header (2 for the handle, 1 for the type,
+1 for the size), the rest is used by the record data. This value doesn't
+take text strings into account (these are placed at the end of the record),
+so the actual length of the record may be (and is often) greater than the
+displayed value.
+.IP \(bu
+Decoded values. The information presented of course depends on the type
+of record. Here, we learn about the board's manufacturer, model, version
+and serial number.
+
+.SH OPTIONS
+.TP
+.BR "-d" ", " "--dev-mem FILE"
+Read memory from device \fBFILE\fR (default: \fB/dev/mem\fR)
+.TP
+.BR "-q" ", " "--quiet"
+Be less verbose. Unknown, inactive and \s-1OEM\s0-specific entries are not
+displayed. Meta-data and handle references are hidden.
+.TP
+.BR "-s" ", " "--string KEYWORD"
+Only display the value of the \s-1DMI\s0 string identified by \fBKEYWORD\fR.
+\fBKEYWORD\fR must be a keyword from the following list: \fBbios-vendor\fR,
+\fBbios-version\fR, \fBbios-release-date\fR,
+\fBsystem-manufacturer\fR, \fBsystem-product-name\fR,
+\fBsystem-version\fR, \fBsystem-serial-number\fR,
+\fBsystem-uuid\fR,
+\fBbaseboard-manufacturer\fR, \fBbaseboard-product-name\fR,
+\fBbaseboard-version\fR, \fBbaseboard-serial-number\fR,
+\fBbaseboard-asset-tag\fR, \fBchassis-manufacturer\fR,
+\fBchassis-type\fR,
+\fBchassis-version\fR, \fBchassis-serial-number\fR,
+\fBchassis-asset-tag\fR, \fBprocessor-family\fR,
+\fBprocessor-manufacturer\fR,
+\fBprocessor-version\fR, \fBprocessor-frequency\fR.
+Each keyword corresponds to a given \s-1DMI\s0 type and a given offset
+within this entry type.
+Not all strings may be meaningful or even defined on all systems. Some
+keywords may return more than one result on some systems (e.g.
+\fBprocessor-version\fR on a multi-processor system).
+If \fBKEYWORD\fR is not provided or not valid, a list of all valid
+keywords is printed and
+.B dmidecode
+exits with an error.
+This option cannot be used more than once.
+.TP
+.BR "-t" ", " "--type TYPE"
+Only display the entries of type \fBTYPE\fR. \fBTYPE\fR can be either a
+\s-1DMI\s0 type number, or a comma-separated list of type numbers, or a
+keyword from the following list: \fBbios\fR, \fBsystem\fR,
+\fBbaseboard\fR, \fBchassis\fR, \fBprocessor\fR, \fBmemory\fR,
+\fBcache\fR, \fBconnector\fR, \fBslot\fR. Refer to the DMI TYPES section
+below for details.
+If this option is used more than once, the set of displayed entries will be
+the union of all the given types.
+If \fBTYPE\fR is not provided or not valid, a list of all valid keywords
+is printed and
+.B dmidecode
+exits with an error.
+.TP
+.BR "-u" ", " "--dump"
+Do not decode the entries, dump their contents as hexadecimal instead.
+Note that this is still a text output, no binary data will be thrown upon
+you. The strings attached to each entry are displayed as both
+hexadecimal and \s-1ASCII\s0. This option is mainly useful for debugging.
+.TP
+.BR " " " " "--dump-bin FILE"
+Do not decode the entries, instead dump the DMI data to a file in binary
+form. The generated file is suitable to pass to \fB--from-dump\fR
+later.
+.TP
+.BR " " " " "--from-dump FILE"
+Read the DMI data from a binary file previously generated using
+\fB--dump-bin\fR.
+.TP
+.BR "-h" ", " "--help"
+Display usage information and exit
+.TP
+.BR "-V" ", " "--version"
+Display the version and exit
+.P
+Options --string, --type and --dump-bin
+determine the output format and are mutually exclusive.
+
+.SH "DMI TYPES"
+The \s-1SMBIOS\s0 specification defines the following \s-1DMI\s0 types:
+
+.TS
+r l
+__
+r l.

+.SH SYNOPSIS
+.B ownership
+.RB [ OPTIONS ]
+
+.SH DESCRIPTION
+.B ownership
+retrieves and prints the "ownership tag" that can be set on Compaq
+computers. Contrary to all other programs of the
+.B dmidecode
+package,
+.B ownership
+doesn't print any version information, nor labels, but only the raw
+ownership tag. This should help its integration in scripts.

+.SH NAME
+vpddecode \- \s-1VPD\s0 structure decoder
+.SH SYNOPSIS
+.B vpddecode
+.RB [ OPTIONS ]
+
+.SH DESCRIPTION
+.B vpddecode
+prints the "vital product data" information that can be found in almost
+all IBM and Lenovo computers. Available items are:
+.IP \(bu "\w'\(bu'u+1n"
+\s-1BIOS\s0 Build \s-1ID\s0
+.IP \(bu
+Box Serial Number
+.IP \(bu
+Motherboard Serial Number
+.IP \(bu
+Machine Type/Model
+
+.PP
+Some systems have these additional items:
+.IP \(bu "\w'\(bu'u+1n"
+BIOS Release Date
+.IP \(bu
+Default Flash Image File Name
+
+.PP
+Note that these additional items are not documented by IBM, so this is
+guess work, and as such should not be blindly trusted. Feedback about
+the accuracy of these labels is welcome.
+
+.SH OPTIONS
+.TP
+.BR "-d" ", " "--dev-mem FILE"
+Read memory from device \fBFILE\fR (default: \fB/dev/mem\fR)
+.TP
+.BR "-s" ", " "--string KEYWORD"
+Only display the value of the \s-1VPD\s0 string identified by \fBKEYWORD\fR.
+\fBKEYWORD\fR must be a keyword from the following list: \fBbios-build-id\fR,
+\fBbox-serial-number\fR, \fBmotherboard-serial-number\fR,
+\fBmachine-type-model\fR, \fBbios-release-date\fR.
+Each keyword corresponds to an offset and a length within the \s-1VPD\s0
+record.
+Not all strings may be defined on all \s-1VPD\s0-enabled systems.
+If \fBKEYWORD\fR is not provided or not valid, a list of all valid
+keywords is printed and
+.B vpddecode
+exits with an error.
+This option cannot be used more than once.
+Mutually exclusive with \fB--dump\fR.
+.TP
+.BR "-u" ", " "--dump"
+Do not decode the VPD records, dump their contents as hexadecimal instead.
+Note that this is still a text output, no binary data will be thrown upon
+you. ASCII equivalent is displayed when possible. This option is mainly
+useful for debugging.
+Mutually exclusive with \fB--string\fR.
+.TP
+.BR "-h" ", " "--help"
+Display usage information and exit
+.TP
+.BR "-V" ", " "--version"
+Display the version and exit
