Sure it does.  I've been running my miata off an IDE disk for quite
a while now.  The other trick to use, if you really want SCSI is
to get any old SCSI card and netboot with a kernel that is hardwired
to have root on SCSI.  That way you don't have to worry about
whether your SCSI card is supported by the SRM.  This also works
for IDE drives---get a tiny one and put exactly a kernel on it.

The IDE drive is accessed via:

>>> boot dka0

IIRC (but my alpha is at home.)

It is a fun machine, I've used it in the following configurations
with NetBSD with success:

	1.  netboot w/ root and all disks on NFS,
	2.  netboot kernel with all disks on Adaptec SCSI controller,
	3.  boot IDE with all disks on Adaptec SCSI controller, and
	4.  boot and all disks on IDE.

I guess that recently I removed the SCSI controller, since I needed
to toss in a second graphics card so that I could dual head the
machine.  And that appears to be working pretty well, too.
