a NCR/Symbios 53C810 based adapter, or a Qlogic 1020/1040 based adapter.
Some machines come with a SCSI chip embedded on the mainboard. Newer machine
designs and SRM versions will be able to work with later SCSI chips/adapters.

of this discussion only refers to Symbios chips, this is meant to include
the older chips that still have NCR stamped on them. Symbios bought the NCR
designs.

WinNT boxes. The ARC or AlphaBIOS knows about *other* adapter types that it
