I'm not sure about 48MB DOCs, but with 256 MB DOC 2000 TSOPs, DFORMAT 5.1.4 installs an initial program loader that wants grub_firmware to have properties different than the ones the GRUB build process makes. In particular, it wants the first 12KB to have a checksum of 0x55 rather than the first 8KB.

On the other hand, DFORMAT is aware of the different DOC models and treats them differently, so this may not apply to the 48M DOC. If you can boot DOS from a floppy, you can use DOS DEBUG to look at the initial program loader in the DOC memory window. With a little effort, you can figure out what the IPL wants grub_firmware to look like.

i'm following mark meade's DOC-GRUB how-to to the letter for installing GRUB on my M-Systems DOC2000 48M unit, but have hit a wall. i've been scouring the list archives for help with no luck, so i ask you...

after using DFORMAT 5.1.4:
DFORMAT /win:E000 /BDKF0:grub_firmware

i reboot system and the message "DoC found" scrolls on the screen about 8 times, and then the computer reboots.

Aren't you supposed to use DFORMAT 4.2 to be compatible with the Grub code?
