tar_files are the tar'd up source (tarred every weekend, note the ftp
server'll be down this weekend). src is the source tree, updated from the
CVS server every few hours.

That sounds like a bad driver design. I think there's a cleaner and easier
way to do this. Grab the source, and check out sys/dev/scsipi, sys/dev/pci
(especially the pciide stuff), and sys/arch/mac68k/nubus.

It sounds like what you want to do is add a nubus card (to
sys/arch/mac68k/nubus) which provides a wdc attachment. So you're
attaching a standard IDE controller. Then the whole rest of the kernel
just treats it like any other IDE controller. If you hook up an atapi
CD-ROm, the right things happen. The wd driver will attach IDE disks.

Trying to emulate a scsi drive would be a whole lot of extra work, and a
lot more things to go wrong.

Take care,
