You want a PCI NCR810 derived device. In other words, NCR/Symbios/LSI
Logic device, that works under the 53c8XX driver.

This line of scsi adapter was the native unit on most Sun and DEC (mips or
alpha) workstations for years as well as being common for PC use. It is a
(more or less) defacto standard unit in that Sun and DEC openboot systems
can use these cards nativly (just like the onboard controller). If one
were to add a Symbios/LSI 8751SPE to a PCI capable Sun or Alpha system it
would detect just like the native (onboard) SCSI controllers (it is the
same chip).

Note, anything LSI that is Ultra2 or faster is *not* 53c8XX type, but
something else.

My fav unit was the 8751SPE, produced as a Symbios unit, and as a LSI unit
(post LSI buyout). It is a standard PCI device, Ultra-Wide SCSI,
narrow/wide internal connectors, wide external connector.
