As I recall, the Everex 3000 used a 12Mhz i/o bus which didn't work with
Microport's V/AT hard disk driver (The controller couldn't handle a "rep
move string" at a full 12Mhz)

Microport Tech Support *had* a disk which would let you run on machines with
a faster i/o bus - we replaced the rep stuff with a discrete mov + jmp loop
which ran slow enough to let the controller work. :-)
