Hello,

The first question is does any NetBSD version run on a MV 4000/100?
http://www.netbsd.org/Ports/vax/models.html lists several models
of 4000 but not the 4000/100.

I tried using the NetBSD 1.6 ISO image to boot my 4000/100 and it just
hangs:

>>>boot dka300:
(BOOT/R5:0 DKA300:)

   2..
-DKA300
   1..0..

The same things happens when trying to boot from ethernet as well --
the machine just hangs.

Any clue on what's going on and how to get the install going?

The system is configured with 64MB RAM, a 4GB SCSI drive, and a CDROM.
The S3 switch is set in the UP position. All boot diagnostics says the
machine is okay. Both the CDROM and CD have been used successful in
two 3100.

Thanks,

-- Michael
