I get the same result with either the non-A/V or the A/V version of v4.1.

Are you able to boot from your 2940?

If so, what does your printenv look like, and how do you specify the
boot-device and boot-file?  Is there a trick?

How do I boot my boot-loader and kernel from the scsi bus and then mount
the 2940 scsi drive partitions on / , /usr, and so forth, and run netbsd?

I suppose I could set up a root device on an external scsi  Jaz drive
and just use the 2940 device as /usr, /var, /home, /work, and so forth,
but that is kind of crude.  Plus, I lose access to the Jaz.
