Using Powermac G3 Parts in G4

How would I use the SCSI PCI card from my older Powermac G3 Server in my Powermac G4? System profiler says that it is connected, but no drivers are installed for it. Also, it doens't appear in the "Parallel SCSI" menu. Any help would be appriciated!

Japamac is absolutely right, of course.


I have both Tiger and Leopard boot drives in my G5 Quad which has an outstanding ATTO SCSI card (originally recommended by japamac himself), and I find myself booted into Tiger just about 99.99999% of the time.

Hi everyone!


Some of the statements made are not entirely true. My G4 MDD is running OS X 10.5.8 Leopard and I have a PCI

SCSI card that works fine with my large UMAX SCSI large format scanner. It's a card that has original SCSI connection.

It's not an SCSI II card.

I think I had to copy the card's kext extensions, though, from my OS X 10.4.11 Tiger drive to my OS X 10.5.8 drive to get the card to be recognized and the scanner recognized in OS X 10.5.

Once I did this, the scanner and SCSI card work fine.

That's because Leopard doesn't support SCSI worth squat!


I keep a Tiger volume for the sole purpose of running my Adaptec SCSI card and Coolscan III scanner.

I tried everything, work around wise, because one of the things that Leopard dropped support for was SCSI.


In the end, Tiger provides for a fine SCSI environment.
