The 174x is now supported. The Ultrastor EISA boards are not supported
in native mode.

0.

Yes. The alpha drivers, from tsx-11.mit.edu:/pub/linux/ALPHA/scsi
explicitly support the 174x in native mode, and also do scatter / gather.

Yes.

Yes.

Yes - the alpha SCSI drivers scatter/gather, and will talk to multiple devices
at the same time.

Removeable hard disks, flopticals, CD-ROM, and tape.
