As usual, this list has proved invaluable in solving problems.
First, thanks to Brendan Choi <bchoi@best.com> and Buddy Lumpkin
<blumpkin@ijapan.com> for pointing me towards the CPU modules. Since this
a dual machine, I pulled the top CPU and tried a boot again. The first test
failed, so I swapped the CPU with the lower unit and had success. I then put
all my memory DIMMS back in and things still worked just peachy.
A few others pointed me towards CDROM issues. I had thought of that (but
failed to mention it in my posting) and switched to the genuine Sun 2x
internal that I had available. It met with the same error.
As of this time, I've fully re-installed the machine and will soon be
installing my software.
Thanks again to everyone.
