This is exactly the same problems that I have been seeing. ASUS PVI486SP3
mainboard with Adaptec 2940 PCI SCSI card. I was also using a PCI CL5436
graphics card. (Although I also tried an ISA graphics card with no more
success) I tried 2 mainboards, and 2 SCSI cards. It worked perfectly with
an ISA SCSI card (Adaptec, not sure it's model - it's quite old)

The machine would lock-up during the newfs stage of the install.

The same cards, memory & disks worked perfectly in an ASUS P120.
