I don't think you will have any luck with an Adaptec card. The SCSI driver in OS4 is for LSI53C8xx chips, and only cards with one of this series will work.
I've been using a DC-2976UW card from DAWIControl in my A1 XE G4. You should be able to get this to work in any A1.
For what it's worth, I also used to use a SB Live! 5.1 sound card in that machine, and that worked fine too (well, within expectations for that card at least
), so I'm not sure why it wouldn't work for you. What went wrong? (Is there another thread where you discuss it?)
Best regards,
Niels
