a) Apply Mark Meade's unification of DiskOnChip 2000 and 
DiskOnChip Millennium code.  Just as with stage2 or Linux 
MTD DiskOnChip driver,  the stage1 code will determine page 
size by looking at the manufacturer and chip ID numbers.

b) Read chip ID into the stage2 RAM area.

c) Add floppy drive BIOS access as a last resort when looking 
for /boot/grub/menu.lst.

Summary:  add possibility to boot off the DiskOnChip flash device

Original Submission:  This is a request to add a compile time configuration 
option that
would allow to store GRUB bootloader on DiskOnChip flash memory
device and boot off it.

The DiskOnChip flash device is usually available to the system 
via the 8 KiB I/O memory window (chip select mechanism?) and can
be detected by BIOS as an extension device.

We are waiting for the copyright being assigned to the FSF.
I'm going to apply the patch, once the copyright problem is
resolved.
