The problem is a driver bug; the error from the controller is misleading, and I believe in reality it reflects a corrupt command being issued. Unfortunately, I have neither card nor controller to verify this with, and have been waiting for some enterprising individual to look at the failing command (printing it is relatively easy) and tell me what's wrong. There are no differences between the i386 and Alpha drivers; the same problem manifests on 2.xx and 3.xx firmware cards on i386 systems. > > =D8ystein Andreassen writes: > >=20 > > Hello, > >=20 > > I have tried to install FreeBSD 4.5 (Release(?)) on a Digital Server= > 5000 > > Model 5303 6533A. > > It has a MyLex KZPAC PCI RAID Controller.
