I found a sun 3/160 tower at the local hardware surplus.  The tower doesn't
appear to have the SCSI option.  I have been trying to get NetBSD to boot,
but the kernel appears to have trouble with the 2nd NIC.  The
"RAM CONFIG FAILED" doesn't look good.  What am I missing?  TIA.

Here's the 3/160 VME card cage config.  These are the settings that came
with the tower -- I didn't change them:
