FreeBSD 4.5 and 5.2.1

[Walter]

I have both of the above mentioned versions. For some reason or other,
neither one will get past the part of the installation where they probe
for hardware. I've let both versions get after it for over 2 hours, and
they're still probing for hardware. Any suggestions as to what I should
be doing to not have this happen? The machine I'm trying this on has an
AMD Duron CPU running at just over 1 Gig.
 
Any info would be appreciated.  Thanks.
