Back when I was trying to reverse-engineer the DiskOnChip drivers, I used
to run it in dosemu, having configured dosemu to give direct access to the
memory window of the DiskOnChip. You should find that works. Best to make
sure you have a backup plan first, though.
Or you could get an ISA evaluation board, pull the DiskOnChip out of your
device and use the eval board to plug it into a 'real' PC.
It's also possible to use the MTD drivers to write the firmware to the
device. The doc_loadbios program will do that for you. The only
complication is that the .exb files shipped by M-Systems aren't a straight
image of what to put on the flash; it should be fairly simple to convert
