It is also possible to add SCSI buses. I have a NuBus SCSI card that has a 53c9x chip of some flavor on it, although I haven't tried it and suspect that it would take some work to get it supported in Linux. Having a NuBus SCSI card was a good option to upgrade performance of some of the mid-range systems where Apple was still using the NCR5380 but better chips were available. I'm pretty sure Apple supported booting off these as long as they had the correct software in the ROM on the card. Brad Boyer flar@allandria.com
