I have a MicroVAX 3100 (KA-41D) on which I am attempting to
install NetBSD.

Using Ultrix I've put tk50-file1-12G and tk50-file2-12G onto a
SCSI TK50 (a TZ30), when I try and boot from it I get:

(the following has been read from one terminal and typed into
another)

Is what I'm attempting (booting a KA-41D MicroVAX from a TZ30 with
1.2G) possible ?, are the parameters to
: st(0,5,4,0)edlabel
correct ?.

Apologies if I've missed something obvious about this in the
documentation.

Thanks,
