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 them though. -- dwmw2 To unsubscribe, send "unsubscribe mtd" to majordomo@infradead.org
