You don't *have* to use DOS, it just might be slightly easier to run DFORMAT
to erase GRUB and return the DoC to its "virgin" state.

compiled as modules, and do your "insmod" or "modprobe" *after* hot-plugging
the DoC. You would also need to use "eraseall" to wipe out GRUB, and I
didn't recommend that option because of the possibility of wiping out the bad

To clarify, "an empty DoC board" simply means inserting the ISA or PCI eval
board, without installing the DoC. Obviously, this would allow you to boot
without the DoC GRUB taking over, and then you could "hot-plug" the DoC to
Keep in mind that these instructions assume a PC and a M-Sys eval-board. If
your system is different, please post the specifics.
For what it's worth, my development PC has an ISA eval-board, and the ability
to "network" boot. My target system has a *socketed* DoC, with no monitor or
keyboard. I make sure the DoC is bootable (from (dc0,0) with root file
system on /dev/nftla1) prior to installing it on my target.
What version of GRUB did you use, prior to applying the patch? I'm still
curious as to why it doesn't recognize your root filesystem. Are you running
GRUB on your hard drive?
