23 the name of your SCSI host adapter (the card inside your computer
24 that "speaks" the SCSI protocol, also called SCSI controller),
25 because you will be asked for it.
27 You also need to say Y here if you have a device which speaks
28 the SCSI protocol. Examples of this include the parallel port
29 version of the IOMEGA ZIP drive, USB storage devices, Fibre
30 Channel, and FireWire storage.

105 tristate "SCSI OnStream SC-x0 tape support"
108 The OnStream SC-x0 SCSI tape drives cannot be driven by the
109 standard st driver, but instead need this special osst driver and
110 use the /dev/osstX char device nodes (major 206). Via usb-storage,
111 you may be able to drive the USB-x0 and DI-x0 drives as well.
112 Note that there is also a second generation of OnStream
113 tape drives (ADR-x0) that supports the standard SCSI-2 commands for
114 tapes (QIC-157) and can be driven by the standard driver st.
115 For more information, you may have a look at the SCSI-HOWTO
116 <http://www.tldp.org/docs.html#howto> and
117 <file:Documentation/scsi/osst.txt> in the kernel source.
118 More info on the OnStream driver may be found on
119 <http://sourceforge.net/projects/osst/>
120 Please also have a look at the standard st docu, as most of it
121 applies to osst as well.

144 This enables the usage of vendor specific SCSI commands. This is
145 required to support multisession CDs with old NEC/TOSHIBA cdrom
146 drives (and HP Writers). If you have such a drive and get the first
147 session only, try saying Y here; everybody else says N.
150 tristate "SCSI generic support"
153 If you want to use SCSI scanners, synthesizers or CD-writers or just
154 about anything having "SCSI" in its name other than hard disks,
155 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
156 directly, so you need some additional software which knows how to
157 talk to these devices using the SCSI protocol:
159 For scanners, look at SANE (<http://www.sane-project.org/>). For CD
160 writer software look at Cdrtools
161 (<http://cdrecord.berlios.de/private/cdrecord.html>)
162 and for burning a "disk at once": CDRDAO
163 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
164 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
165 For other devices, it's possible that you'll have to write the
166 driver software yourself. Please read the file
167 <file:Documentation/scsi/scsi-generic.txt> for more information.
169 To compile this driver as a module, choose M here and read
170 <file:Documentation/scsi/scsi.txt>. The module will be called sg.
175 tristate "SCSI media changer support"
178 This is a driver for SCSI media changers. Most common devices are
179 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
180 don't need this for those tiny 6-slot cdrom changers. Media
181 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
182 If you have such hardware and want to use it with linux, say Y
183 here. Check <file:Documentation/scsi/scsi-changer.txt> for details.
185 If you want to compile this as a module ( = code which can be
186 inserted in and removed from the running kernel whenever you want),
187 say M here and read <file:Documentation/kbuild/modules.txt> and
188 <file:Documentation/scsi/scsi.txt>. The module will be called ch.o.
191 config SCSI_ENCLOSURE
192 tristate "SCSI Enclosure Support"
193 depends on SCSI && ENCLOSURE_SERVICES
195 Enclosures are devices sitting on or in SCSI backplanes that
196 manage devices. If you have a disk cage, the chances are that
197 it has an enclosure device. Selecting this option will just allow
198 certain enclosure conditions to be reported and is not required.
200 config SCSI_MULTI_LUN
201 bool "Probe all LUNs on each SCSI device"
204 Some devices support more than one LUN (Logical Unit Number) in order
205 to allow access to several media, e.g. CD jukebox, USB card reader,
206 mobile phone in mass storage mode. This option forces the kernel to
207 probe for all LUNs by default. This setting can be overriden by
208 max_luns boot/module parameter. Note that this option does not affect
209 devices conforming to SCSI-3 or higher as they can explicitely report
210 their number of LUNs. It is safe to say Y here unless you have one of
211 those rare devices which reacts in an unexpected way when probed for
214 config SCSI_CONSTANTS
215 bool "Verbose SCSI error reporting (kernel size +=12K)"
218 The error messages regarding your SCSI hardware will be easier to
219 understand if you say Y here; it will enlarge your kernel by about
220 12 KB. If in doubt, say Y.
223 bool "SCSI logging facility"
226 This turns on a logging facility that can be used to debug a number
227 of SCSI related problems.
229 If you say Y here, no logging output will appear by default, but you
230 can enable logging by saying Y to "/proc file system support" and
231 "Sysctl support" below and executing the command
233 echo <bitmask> > /proc/sys/dev/scsi/logging_level
235 where <bitmask> is a four byte value representing the logging type
236 and logging level for each type of logging selected.
238 There are a number of logging types and you can find them in the
239 source at <file:drivers/scsi/scsi_logging.h>. The logging levels
240 are also described in that file and they determine the verbosity of
241 the logging for each logging type.
243 If you say N here, it may be harder to track down some types of SCSI
244 problems. If you say Y here your kernel will be somewhat larger, but
245 there should be no noticeable performance impact as long as you have
248 config SCSI_SCAN_ASYNC
249 bool "Asynchronous SCSI scanning"
252 The SCSI subsystem can probe for devices while the rest of the
253 system continues booting, and even probe devices on different
254 busses in parallel, leading to a significant speed-up.
256 If you have built SCSI as modules, enabling this option can
257 be a problem as the devices may not have been found by the
258 time your system expects them to have been. You can load the
259 scsi_wait_scan module to ensure that all scans have completed.
260 If you build your SCSI drivers into the kernel, then everything
261 will work fine if you say Y here.
263 You can override this choice by specifying "scsi_mod.scan=sync"
264 or async on the kernel's command line.

344 SCSI requests and responses over a TCP/IP network between the host
345 (the "initiator") and "targets". Architecturally, the iSCSI driver
346 combines with the host's TCP/IP stack, network drivers, and Network

720 signature. The addresses of all the PCI SCSI controllers reported
721 by the PCI subsystem are probed as well.
723 You want to read the start of <file:drivers/scsi/eata.c> and the
724 SCSI-HOWTO, available from
725 <http://www.tldp.org/docs.html#howto>.
727 To compile this driver as a module, choose M here: the
728 module will be called eata.
730 config SCSI_EATA_TAGGED_QUEUE
731 bool "enable tagged command queueing"
734 This is a feature of SCSI-2 which improves performance: the host
735 adapter can send several SCSI commands to a device's queue even if
736 previous commands haven't finished yet.
737 This is equivalent to the "eata=tc:y" boot option.
739 config SCSI_EATA_LINKED_COMMANDS
740 bool "enable elevator sorting"
743 This option enables elevator sorting for all probed SCSI disks and
744 CD-ROMs. It definitely reduces the average seek distance when doing
745 random seeks, but this does not necessarily result in a noticeable
746 performance improvement: your mileage may vary...
747 This is equivalent to the "eata=lc:y" boot option.
749 config SCSI_EATA_MAX_TAGS
750 int "maximum number of queued commands"
754 This specifies how many SCSI commands can be maximally queued for
755 each probed SCSI device. You should reduce the default value of 16
756 only if you have disks with buggy or limited tagged command support.
757 Minimum is 2 and maximum is 62. This value is also the window size
758 used by the elevator sorting option above. The effective value used
759 by the driver for each probed SCSI device is reported at boot time.
760 This is equivalent to the "eata=mq:8" boot option.
763 tristate "EATA-PIO (old DPT PM2001, PM2012A) support"
764 depends on (ISA || EISA || PCI) && SCSI && BROKEN
766 This driver supports all EATA-PIO protocol compliant SCSI Host
767 Adapters like the DPT PM2001 and the PM2012A. EATA-DMA compliant
768 host adapters could also use this driver but are discouraged from
769 doing so, since this driver only supports hard disks and lacks
770 numerous features. You might want to have a look at the SCSI-HOWTO,
771 available from <http://www.tldp.org/docs.html#howto>.

781 This is support for Future Domain's 16-bit SCSI host adapters
782 (TMC-1660/1680, TMC-1650/1670, TMC-3260, TMC-1610M/MER/MEX) and
783 other adapters based on the Future Domain chipsets (Quantum
784 ISA-200S, ISA-250MG; Adaptec AHA-2920A; and at least one IBM board).
785 It is explained in section 3.7 of the SCSI-HOWTO, available from
786 <http://www.tldp.org/docs.html#howto>.
788 NOTE: Newer Adaptec AHA-2920C boards use the Adaptec AIC-7850 chip
789 and should use the aic7xxx driver ("Adaptec AIC7xxx chipset SCSI
790 controller support"). This Future Domain driver works with the older
791 Adaptec AHA-2920A boards with a Future Domain chip on them.

798 depends on (ISA || EISA || PCI) && SCSI && ISA_DMA_API
800 Formerly called GDT SCSI Disk Array Controller Support.
802 This is a driver for RAID/SCSI Disk Array Controllers (EISA/ISA/PCI)

820 tristate "Generic NCR5380/53c400 SCSI PIO support"
821 depends on ISA && SCSI
822 select SCSI_SPI_ATTRS
824 This is a driver for the old NCR 53c80 series of SCSI controllers
825 on boards using PIO. Most boards such as the Trantor T130 fit this
826 category, along with a large number of ISA 8bit controllers shipped
827 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
828 you should select the specific driver for that card rather than
829 generic 5380 support.
831 It is explained in section 3.8 of the SCSI-HOWTO, available from

856 depends on SCSI_GENERIC_NCR5380
858 This enables certain optimizations for the NCR53c400 SCSI cards.
859 You might as well try it out. Note that this driver will only probe
860 for the Trantor T130B in its default configuration; you might have
861 to pass a command line option to the kernel at boot time if it does
862 not detect your card. See the file

946 depends on SCSI && PARPORT_PC
948 This driver supports older versions of IOMEGA's parallel port ZIP
949 drive (a 100 MB removable media device).
951 Note that you can say N here if you have the SCSI version of the ZIP
952 drive: it will be supported automatically if you said Y to the
953 generic "SCSI disk support", above.
955 If you have the ZIP Plus drive or a more recent parallel port ZIP
956 drive (if the supplied cable with the drive is labeled "AutoDetect")

999 bool "ppa/imm option - Use slow (but safe) EPP-16"
1000 depends on SCSI_PPA || SCSI_IMM
1002 EPP (Enhanced Parallel Port) is a standard for parallel ports which
1003 allows them to act as expansion buses that can handle up to 64
1006 Some parallel port chipsets are slower than their motherboard, and
1007 so we have to control the state of the chipset's FIFO queue every
1008 now and then to avoid data loss. This will be done if you say Y
1011 Generally, saying Y is the safe option and slows things down a bit.
1013 config SCSI_IZIP_SLOW_CTR
1014 bool "ppa/imm option - Assume slow parport control register"
1015 depends on SCSI_PPA || SCSI_IMM
1017 Some parallel ports are known to have excessive delays between
1018 changing the parallel port control register and good data being
1019 available on the parallel port data/status register. This option
1020 forces a small delay (1.0 usec to be exact) after changing the
1021 control register to let things settle out. Enabling this option may
1022 result in a big drop in performance but some very old parallel ports
1023 (found in 386 vintage machines) will not work properly.
1025 Generally, saying N is fine.

1044 This is a driver for the MicroChannel Dual 700 card produced by
1045 NCR and commonly used in 345x/35xx/4100 class machines. It always
1046 tries to negotiate sync and uses tag command queueing.
1048 Unless you have an NCR manufactured machine, the chances are that

1096 This driver supports the whole NCR53C8XX/SYM53C8XX family of
1097 PCI-SCSI controllers. It also supports the subset of LSI53C10XX
1098 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
1099 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI
1100 controllers; you need to use the Fusion MPT driver for that.

1105 config SCSI_SYM53C8XX_DMA_ADDRESSING_MODE
1106 int "DMA addressing mode"
1107 depends on SCSI_SYM53C8XX_2
1110 This option only applies to PCI-SCSI chips that are PCI DAC
1111 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1113 When set to 0, the driver will program the chip to only perform
1114 32-bit DMA. When set to 1, the chip will be able to perform DMA
1115 to addresses up to 1TB. When set to 2, the driver supports the
1116 full 64-bit DMA address range, but can only address 16 segments
1117 of 4 GB each. This limits the total addressable range to 64 GB.
1119 Most machines with less than 4GB of memory should use a setting
1120 of 0 for best performance. If your machine has 4GB of memory
1121 or more, you should set this option to 1 (the default).
1123 The still experimental value 2 (64 bit DMA addressing with 16
1124 x 4GB segments limitation) can be used on systems that require
1125 PCI address bits past bit 39 to be set for the addressing of
1126 memory using PCI DAC cycles.

1133 This is the default value of the command queue depth the
1134 driver will announce to the generic SCSI layer for devices
1135 that support tagged command queueing. This value can be changed
1136 from the boot command line. This is a soft limit that cannot
1137 exceed CONFIG_SCSI_SYM53C8XX_MAX_TAGS.
1139 config SCSI_SYM53C8XX_MAX_TAGS
1140 int "Maximum number of queued commands"
1141 depends on SCSI_SYM53C8XX_2
1144 This option allows you to specify the maximum number of commands
1145 that can be queued to any device, when tagged command queuing is
1146 possible. The driver supports up to 256 queued commands per device.
1147 This value is used as a compiled-in hard limit.

1150 bool "Use memory mapped IO"
1151 depends on SCSI_SYM53C8XX_2
1154 Memory mapped IO is faster than Port IO. Most people should

1156 to answer N here, please report the problem to the maintainer.
1159 tristate "IBM Power Linux RAID adapter support"
1160 depends on PCI && SCSI && ATA
1163 This driver supports the IBM Power Linux family RAID adapters.
1164 This includes IBM pSeries 5712, 5703, 5709, and 570A, as well
1165 as IBM iSeries 5702, 5703, 5709, and 570A.
1167 config SCSI_IPR_TRACE

1173 to the adapter. Performance impact is minimal. Trace can be
1174 dumped using /sys/bus/class/scsi_host/hostXX/trace.
1176 config SCSI_IPR_DUMP
1177 bool "enable adapter dump support"
1181 If you say Y here, the driver will support adapter crash dump.

1190 The Zalon is a GSC/HSC bus interface chip that sits between the
1191 PA-RISC processor and the NCR 53c720 SCSI controller on C100,
1192 C110, J200, J210 and some D, K & R-class machines. It's also
1193 used on the add-in Bluefish, Barracuda & Shrike SCSI cards.

1196 config SCSI_NCR_Q720
1197 tristate "NCR Quad 720 MCA SCSI support"
1198 depends on MCA && SCSI
1199 select SCSI_SPI_ATTRS
1201 This is a driver for the MicroChannel Quad 720 card produced by
1202 NCR and commonly used in 345x/35xx/4100 class machines. It always
1203 tries to negotiate sync and uses tag command queueing.
1205 Unless you have an NCR manufactured machine, the chances are that
1206 you do not have this SCSI card, so say N.
1208 config SCSI_NCR53C8XX_DEFAULT_TAGS
1209 int "default tagged command queue depth"
1210 depends on SCSI_ZALON || SCSI_NCR_Q720
1213 "Tagged command queuing" is a feature of SCSI-2 which improves
1214 performance: the host adapter can send several SCSI commands to a
1215 device's queue even if previous commands haven't finished yet.
1216 Because the device is intelligent, it can optimize its operations
1217 (like head positioning) based on its own request queue. Some SCSI
1218 devices don't implement this properly; if you want to disable this
1219 feature, enter 0 or 1 here (it doesn't matter which).
1221 The default value is 8 and should be supported by most hard disks.
1222 This value can be overridden from the boot command line using the
1223 'tags' option as follows (example):
1224 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1225 4, set queue depth to 16 for target 2 and target 3 on controller 0
1226 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1228 The normal answer therefore is to go with the default 8 and to use
1229 a boot command line option for devices that need to use a different
1230 command queue depth.
1232 There is no safe option other than using good SCSI devices.
1234 config SCSI_NCR53C8XX_MAX_TAGS
1235 int "maximum number of queued commands"
1236 depends on SCSI_ZALON || SCSI_NCR_Q720
1239 This option allows you to specify the maximum number of commands
1240 that can be queued to any device, when tagged command queuing is
1241 possible. The default value is 32. Minimum is 2, maximum is 64.
1242 Modern hard disks are able to support 64 tags and even more, but
1243 do not seem to be faster when more than 32 tags are being used.
1245 So, the normal answer here is to go with the default value 32 unless
1246 you are using very large hard disks with large cache (>= 1 MB) that
1247 are able to take advantage of more than 32 tagged commands.
1249 There is no safe option and the default answer is recommended.
1251 config SCSI_NCR53C8XX_SYNC
1252 int "synchronous transfers frequency in MHz"
1253 depends on SCSI_ZALON || SCSI_NCR_Q720
1256 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1257 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1258 are respectively the maximum data transfer rates in mega-transfers
1259 per second for each class. For example, a FAST-20 Wide 16 device is
1260 able to transfer data at 20 million 16 bit packets per second for a
1261 total rate of 40 MB/s.
1263 You may specify 0 if you want to only use asynchronous data
1264 transfers. This is the safest and slowest option. Otherwise, specify
1265 a value between 5 and 80, depending on the capability of your SCSI
1266 controller. The higher the number, the faster the data transfer.
1267 Note that 80 should normally be ok since the driver decreases the
1268 value automatically according to the controller's capabilities.
1270 Your answer to this question is ignored for controllers with NVRAM,
1271 since the driver will get this information from the user set-up. It
1272 also can be overridden using a boot setup option, as follows
1273 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1274 for FAST-20 synchronous data transfer (20 mega-transfers per
1277 The normal answer therefore is not to go with the default but to
1278 select the maximum value 80 allowing the driver to use the maximum
1279 value supported by each controller. If this causes problems with
1280 your SCSI devices, you should come back and decrease the value.
1282 There is no safe option other than using good cabling, right
1283 terminations and SCSI conformant devices.
1285 config SCSI_NCR53C8XX_NO_DISCONNECT
1286 bool "not allow targets to disconnect"
1287 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1289 This option is only provided for safety if you suspect some SCSI
1290 device of yours to not support properly the target-disconnect
1291 feature. In that case, you would say Y here. In general however, to
1292 not allow targets to disconnect is not reasonable if there is more
1293 than 1 device on a SCSI bus. The normal answer therefore is N.

1310 tristate "Qlogic FAS SCSI support"
1311 depends on ISA && SCSI
1313 This is a driver for the ISA, VLB, and PCMCIA versions of the Qlogic
1314 FastSCSI! cards as well as any other card based on the FASXX chip
1315 (including the Control Concepts SCSI/IDE/SIO/PIO/FDC cards).
1317 This driver does NOT support the PCI versions of these cards. The
1318 PCI versions are supported by the Qlogic ISP driver ("Qlogic ISP

1380 depends on ISA && SCSI
1382 This is support for the sym53c416 SCSI host adapter, the SCSI
1383 adapter that comes with some HP scanners. This driver requires that
1384 the sym53c416 is configured first using some sort of PnP
1385 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1386 are using isapnp then you need to compile this driver as a module
1387 and then load it using insmod after isapnp has run. The parameters
1388 of the configured card(s) should be passed to the driver. The format

1400 This driver supports PCI SCSI host adapters based on the ASIC
1401 TRM-S1040 chip, e.g Tekram DC395(U/UW/F) and DC315(U) variants.
1403 This driver works, but is still in experimental status. So better
1404 have a bootable disk and a backup in case of emergency.
1406 Documentation can be found in <file:Documentation/scsi/dc395x.txt>.

1416 chip, e.g. Tekram DC390(T), DawiControl 2974 and some onboard
1417 PCscsi/PCnet (Am53/79C974) solutions.
1419 Documentation can be found in <file:Documentation/scsi/tmscsim.txt>.
1421 Note that this driver does NOT support Tekram DC390W/U/F, which are

1445 tristate "UltraStor 14F/34F support"
1446 depends on ISA && SCSI && ISA_DMA_API
1448 This is support for the UltraStor 14F and 34F SCSI-2 host adapters.
1449 The source at <file:drivers/scsi/u14-34f.c> contains some
1450 information about this hardware. If the driver doesn't work out of
1451 the box, you may have to change some settings in
1452 <file: drivers/scsi/u14-34f.c>. Read the SCSI-HOWTO, available from
1453 <http://www.tldp.org/docs.html#howto>. Note that there is also
1454 another driver for the same hardware: "UltraStor SCSI support",
1455 below. You should say Y to both only if you want 24F support as
1458 To compile this driver as a module, choose M here: the
1459 module will be called u14-34f.
1461 config SCSI_U14_34F_TAGGED_QUEUE
1462 bool "enable tagged command queueing"
1463 depends on SCSI_U14_34F
1465 This is a feature of SCSI-2 which improves performance: the host
1466 adapter can send several SCSI commands to a device's queue even if
1467 previous commands haven't finished yet.
1468 This is equivalent to the "u14-34f=tc:y" boot option.
1470 config SCSI_U14_34F_LINKED_COMMANDS
1471 bool "enable elevator sorting"
1472 depends on SCSI_U14_34F
1474 This option enables elevator sorting for all probed SCSI disks and
1475 CD-ROMs. It definitely reduces the average seek distance when doing
1476 random seeks, but this does not necessarily result in a noticeable
1477 performance improvement: your mileage may vary...
1478 This is equivalent to the "u14-34f=lc:y" boot option.
1480 config SCSI_U14_34F_MAX_TAGS
1481 int "maximum number of queued commands"
1482 depends on SCSI_U14_34F
1485 This specifies how many SCSI commands can be maximally queued for
1486 each probed SCSI device. You should reduce the default value of 8
1487 only if you have disks with buggy or limited tagged command support.
1488 Minimum is 2 and maximum is 14. This value is also the window size
1489 used by the elevator sorting option above. The effective value used
1490 by the driver for each probed SCSI device is reported at boot time.
1491 This is equivalent to the "u14-34f=mq:8" boot option.
1493 config SCSI_ULTRASTOR
1494 tristate "UltraStor SCSI support"
1495 depends on X86 && ISA && SCSI
1497 This is support for the UltraStor 14F, 24F and 34F SCSI-2 host
1498 adapter family. This driver is explained in section 3.12 of the

1508 module will be called ultrastor.
1511 tristate "Workbit NinjaSCSI-32Bi/UDE support"
1512 depends on PCI && SCSI && !64BIT
1514 This is support for the Workbit NinjaSCSI-32Bi/UDE PCI/Cardbus
1515 SCSI host adapter. Please read the SCSI-HOWTO, available from

1518 To compile this driver as a module, choose M here: the
1519 module will be called nsp32.
1522 tristate "SCSI debugging host simulator"
1526 This is a host adapter simulator that can simulate multiple hosts
1527 each with multiple dummy SCSI devices (disks). It defaults to one
1528 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1529 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1530 dummy disks are simulated, they share the same kernel RAM for
1531 their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more
1532 information. This driver is primarily of use to those testing the
1533 SCSI and block subsystems. If unsure, say N.
1536 tristate "MESH (Power Mac internal SCSI) support"
1537 depends on PPC32 && PPC_PMAC && SCSI
1539 Many Power Macintoshes and clones have a MESH (Macintosh Enhanced
1540 SCSI Hardware) SCSI bus adaptor (the 7200 doesn't, but all of the
1541 other Power Macintoshes do). Say Y to include support for this SCSI
1544 To compile this driver as a module, choose M here: the
1545 module will be called mesh.
1547 config SCSI_MESH_SYNC_RATE
1548 int "maximum synchronous transfer rate (MB/s) (0 = async)"
1549 depends on SCSI_MESH
1552 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1553 drives a bus which is entirely internal to the machine (such as the
1554 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1555 operation at up to 10 MB/s. On machines where the SCSI bus
1556 controlled by the MESH can have external devices connected, it is
1557 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1558 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1559 to disable synchronous operation.
1561 config SCSI_MESH_RESET_DELAY_MS
1562 int "initial bus reset delay (ms) (0 = no reset)"
1563 depends on SCSI_MESH
1566 config SCSI_MAC53C94
1567 tristate "53C94 (Power Mac external SCSI) support"
1568 depends on PPC32 && PPC_PMAC && SCSI
1570 On Power Macintoshes (and clones) with two SCSI buses, the external
1571 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1572 machines which only have one SCSI bus, such as the 7200, also use
1573 the 53C94. Say Y to include support for the 53C94.

1657 a compatible SCSI controller (e.g. for Medusa).
1659 To compile this driver as a module, choose M here: the
1660 module will be called atari_scsi.
1662 This driver supports both styles of NCR integration into the
1663 system: the TT style (separate DMA), and the Falcon style (via
1664 ST-DMA, replacing ACSI). It does NOT support other schemes, like
1665 in the Hades (without DMA).
1667 config ATARI_SCSI_TOSHIBA_DELAY
1668 bool "Long delays for Toshiba CD-ROMs"
1669 depends on ATARI_SCSI
1671 This option increases the delay after a SCSI arbitration to
1672 accommodate some flaky Toshiba CD-ROM drives. Say Y if you intend to
1673 use a Toshiba CD-ROM drive; otherwise, the option is not needed and
1674 would impact performance a bit, so say N.
1676 config ATARI_SCSI_RESET_BOOT
1677 bool "Reset SCSI-devices at boottime"
1678 depends on ATARI_SCSI
1680 Reset the devices on your Atari whenever it boots. This makes the
1681 boot process fractionally longer but may assist recovery from errors
1682 that leave the devices with SCSI operations partway completed.
