THere was even a version of 1.1.5.1 that ran on MCA using ABIOS for some theings and a native SCSI driver for others! I could dig out the references for you, but you could didg them out of the list archives yourself just as easily. The current (4.4 based) version of FreeBSD doesn't support MCA at all, but it would be on the order of adding PCI support to make it work, either using the existing MACH code, or using some other approach.
