I noticed that the MOP boot loader I was using was an older version
(1.11), updating it to the current version (1.12) fixed the 'machine
check' error I was seeing when netbooting the generic kernel. My
current state is that I can netboot both the install and generic
kernels with the -a option, the kernels see my CQD card as mscpbus1, I
can mount the SCSI disk (ra0) as root and the system boots normally.

All attempts to boot from disk result in failure to detect mscpbus1.

I've seen the posts about it being a memory size problem but if that is
the case, why does it work when I netboot?
