I struggled for a whole week with no success.
(On an AMPRO CM-P5i, an otherwise nice board)
The driver would hang the system at partition check time.
There is a beta driver for Linux to use the DiskOnChip but I only ever saw
one instance that actually ran...and the source was not available.
M-Systems is the only maker of the software that controls DiskOnChip
devices.  You can get the driver through Tech Support.
The one plus of DoC is that it registers BIOS extensions at boot, and thus
behaves transparently in DOS.
The only way I ever got Linux to boot off a DiskOnChip was to install
DR-DOS on the DoC, boot into DOS and then use loadlin to load a kernel and
ramdisk image into memory.  Thus Linux boots and runs great, but cannot
see the DoC.
(And no, a DoC does not behave anythong like an EEPROM..can't just
read/write to it, it's got a state machine in it, with the operation locked
up tight.)
The M-Systems driver is as un-COSHER as can be...
