[SunHELP] Ultra 1 trouble installing Solaris 9

[austin wood]

Today I tried to install NetBSD, and it worked without any problems.  I'm
inclined to believe that there is no damage to the CPU since the system
works fine with NetBSD.  Are there any other possible reasons for a BAD
TRAP signal?

Thanks,
austin
