I have a limited number of SATA and ATA133 cards but I have a fair number of Ultra SCSI PCI cards that I’ve pretty much never used and some 10,000 rpm hard drives. Earlier this week I was waiting around for a repairman and decided to see which Ultra SCSI cards would work in a beige G3 to boot 10.2. I tried these with no luck

Adaptec AHA-2940U2B

Adaptec AHA-2940UWPI

ATTO ExpressPCI UL3S

ATTO ExpressPCI-DC

ATTO ExpressPCI-PSC

Initio A100U2W

Initio 9100UW

Jackhammer SE

All the Adaptec and ATTO cards would work under 10.2, just not for booting OSX. The Initio and Jackhammer cards wouldn’t work at all under 10.2.

A regular SCSI card, the Adaptec 2930 did work for booting OSX though. They all worked for booting OS9

I also had some Grappler 902F cards. They weren’t Ultra SCSI but were bootable under OS9 but not useable under OSX

Has anyone had success booting any version of OSX off a SCSI card other than the Adaptec 2930?
