The current state is:

  - loading/displaying images works
  - display text works (s. com32/lua/test/vesa.lua)

- PCI:
  - list PC devices + ID
  - get human-readable device name for device
   (s. com32/lua/test/pci.lua)

- DMI:
  - get DMI info (BIOS, Hardware, etc).
  (s. com32/lua/test/dmi.lua)

- syslinux:
  - loading files, kernel, initrd
  - start kernel, initrd, local boot

chain.c32:  add grubcfg= for passing an alternative config filename to GRUB Legacy and cleanup the root partition passing

GRUB Legacy reserves 89 bytes for storing the filename of the configfile
from memory address 0x8217 to 0x826f.
We allow overwriting the default value (/boot/grub/menu.lst) when
grubcfg=<filename> is used together with grub=<loader>.

Examples:
  chain.c32 fs grub=/boot/grub/stage2 grubcfg=/boot/grub/grub.lst
  chain.c32 hd1,10 grub=/boot/grub/stage2 grubcfg=/boot/grub/grub.lst

Use a structure instead of hard-coded offsets for modifying the install_partition variable
(and the configfile name) in the stage2 file.

Add some comments about the "boot information format" of the Multiboot specification, which
is very similar to the install_partition variable used by GRUB Legacy.
