to make a bootable tk50 (or 9trk, though i have no way to try it) you need
to write vmb.exe and the generic standalone kernel on the tape, in that order.
if you have real ultrix 3.x or the ultrix 3.x "server kit", vmb.exe is located
in / and the standalone vmunix is located in /usr/sys/SAS.net.
use dd to write the tape (attached are my notes to myself):
To make a SAS tape, insert a writable TK50, then issue the following
commands:
dd if=/vmb.exe of=/dev/rmt0h obs=512 # write vmb
mt rewind # just to be sure
mt fsf 1 # skip over vmb
dd if=/usr/sys/SAS.net/vmunix of=/dev/rmt0h obs=512 # write generic Ultrix
then boot from the tape with the b mua0
you could also dd the first two files off of your bootable tk50
and then write them on another tape. you can also do this under vms (!!) by
mounting the tape /rec=512 /block=512 and using the vms copy command.
