I ask because the 5.1.2 M-Sys DOS firmware seems to crap out badly if there is
multiple partitions in the DoC disk image.. and it is a bit hard to boot the
system if the DoC firmware does not play..
WIth a single partition everithing works just fine.
If I add another partition to the DoC disk image then the DOS firmware no
longer boots the OS from the DoC, and if I load GRUB or DOS via the netwok
(PXE) then GRUB cannot read the partition table and finds yet another ghost
harddrive in the system, and DOS does not find any partition table on the
DoC.. Funny eh?

I am referring to the MBR of the DoC, not any other device. The DoC emulates a
harddrive and as such it has a MBR for the DOS partition table and OS

With the 5.1.2 version of DFORMAT GRUB installed just fine as a binary flash
image using the DFORMAT dos tool.. only that it didn't like the NTFL
complaining about UnitSizeFactor once booted..
dformat /win:d600 /BDKF0:grub_firmware
Haven't yet had time to test the 4.2 DFORMAT utility. Expect to do so during
