Asking the obvious questions to eliminate them first ...
1. Official CDs?
2. Can you read/copy the CD on *any* machines / *any* OS?
3. Specifically - if you FTP install OpenBSD , can you then mount /

copy / do anything with the CD?
4. dmesg(s)
Personal experience ...
I have installed 3.8 to 4.2 from CDs on machines from P3 500 to

Pentium D 2.something via Celeron 900Mhz (Dells, HPs, Compaqs,

desktops and laptops) - only real issue was a bogus 4.1 CD than no

machine would touch.
I had a CD error with 4.2 today (same CD that I have done 3 installs

with already!) when extracting Xenocara - so I umounted, ejected,

took CD out, waggled it around while saying magic incantation,

remounted, and tried again and it worked (well, no errors reported.)
HTH, YMMV, IANAD, etc.
