I can boot from the diskOnChip and see it as a disk device with a ext2 filesystem using 2.2.18 + Msystem patch + own cooked lilo patch... Now I upgraded the system to a stock 2.4.6 kernel *with devfs enabled* When I boot, I see the follwing message : M-Systems DiskOnChip driver. (C) 1999 Machine Vision Holdings, Inc.
