Original question:

> The 4100 has 2 PCI busses. pci0 is a combination PCI and EISA bus and
> pci1 is only PCI. I have plugged in 4 additional differential SCSI
> controllers and find that only the two that are plugged into pci1 are
> recognised by the system. Even at the level of the SRM and the AlphaBIOS
> the 2 boards on pci0 are invisible. It doesn't seem as if pci0 is broken
> as the display adapter is plugged in thereand it certainly works. Are
> there any suggestions?

There were no responses, however what I did find was that the boards
were poorly designed and that when the installer had aligned the
retaining screws with the notches on the metal tabs that the boards
were poorly seated. I now have that machine setup with 6 SCSI buses
and no problems.
