I have a Power Domain 2940UW controller that I can boot MAC OS8.5.1 from
without any trouble.  However, I can not boot NetBSD from it.

Under OF, when I do a "dev /bandit/ADPT,2940UW" I get an "ok".  When I
enter "words", I also get an "ok", but no "open".  As far as I can tell,
the controller should not boot the disk, according to the literature and
FAQ.  When I try to boot NetBSD from OF, I just get a statement that I
cannot open the disk.

As a test, I repartitioned the same Barracuda 4Gig disk and installed
MacOS 8.5.1, and it boots just fine! I understand that if I can boot Mac
OS from the device, I should be able to boot NetBSD.

Settings for OF are:

"setenv boot-device /bandit/ADPD,2940UW@6:0"
"setenv boot-file netbsd"
"setenv load-base 600000"
"setenv real-base F00000"

I am using the modified system disk utility, and all that stuff. I got
this system, NetBSD, to run off a La Cie scsi Jaz drive, using the
internal scsi controller just fine, so I have a lot of experience with
OF and macppc now.  Also running the i386 version for a couple of years.

Any ideas?

Thanks in advance.
