This is follow up to a previously posted challenge to virtualize VenturComm Venix/86 so that it can be run on a modern machine under an emulator. The competition was a huge success and the rest of this post is an entry by the winner – Jim Carpenter. Enjoy!
Install MAME/MESS 0.164 and get the “at386” machine running. Standard issue ROMs.
Create a new hard drive image with “chdman createhd -chs 615,4,17 -c none -o hd.chd“. This is only 20MB. You can certainly use larger drives but make them a standard type, something that is a defined drive type in the BIOS. I’d stay away from user defined types.

Restart again. (Venix uses the BIOS for *everything*. So if you attach without rebooting, chances are the BIOS missed your hard drive which means Venix won’t see it either.)
We wish to prepare the winchester hard disk:
