The SCSI card is a Symbios Logic 53c875, the network card a DEC 21140A, the CD/DVD is ATAPI, and the disks are at ID 0 and 1:
It's 'spelt' "DEC 21140A" but is pronounced "Tulip" :>
I have had an Adaptec 39160 SCSI card in (note that a 29160 does not work), but that lost against a lightning strike. The IDE controller is the same (horrible) chipset that also appears in some Sun machines (U5, U10, etc.): cmdide0: CMD Technology PCI0646 (rev. 0x01)
Also B&W smurf-tower Mac's. They have a DMA bug. There's some sofware work-arounds that prevent the chain locking up.
You might be able to use the u160 cotnroller inside nbsd. I had a ds20 driving a yum-cha brand SATA controller after a bit of kernel fiddling. You can't boot of it, but heck.. load the kernel off some old scsi disk or MOP and go gang-busters from there. Also with with u160's eg the i2o dev I have, I had to first set it up in a PeeCee and set all the disks to jbod and save the config to the card because I couldn't drive the bios on the alpha and the rotten thing wouldn't come up in 'dumb mode' and present the drives. First had to go make separate vdisks for each vol.
