I am having trouble getting my SUN 3/50 (a dataless machine) to boot from its own disk. If I try b sd() or b sd(,2), nothing happens (the local disk is addressed as sd2). If I try b le() -a, and get the process started from the machine used to set up the 3/50, then tell it to boot vmunix from the local disk (sd2) all goes well. One possibility: the disk used to be a second disk on the server and then was moved, so it may not be terminated properly. Is this the problem? Any other suggestions ?

Sounds like the disk is missing the infamous boot block, no problem. Check out the installboot command: I have used it a few times. On 4.0.3 try cd /usr/kvm/mdec installboot -vlt /boot bootsd /dev/rsd2a try 'man installboot' to find out exactly what it does Note pre 4.0 systems the installboot behaves slightly differently. fbresz@ittc.wec.com uunet!ittc!fbresz

If you really want to install the bootblock, then do: cd /usr/kvm/mdec installboot -vl /boot bootsd /dev/rsd2a (I ran into this one once myself when I was wandering why the #$%^ it did not work ;-) ) Wolfgang Wetz, Systems Administrator *** CIBA-GEIGY AG, R-1045.P.24, P.O.Box, CH-4002 Basel, Switzerland *** E-mail: cgch!wwtz@relay.EU.net - Phone: +4161 697 54 25 - Fax: +4161 697 32 88
