Perhaps you can explain to me how you think the test was flawed?
Also, could you please tell me where you got the 100% scaled and 80% scaled
values?  I did not quote them, and I must be blind, because I can't find them
in the article...

FreeBSD had talk of patches for SMP, but I never looked for them or used them.
The Compaq, to the best of my knowledge, is Collorroly(sp?) compatiable 
SMP.  They have a lock on the intel market, since the vast majority of SMP x86
machines are based on their methods.  We support Everex MP boxes based on
this standard.  We also sell Compaq SMP, but both machine run SCO unix and I
have never tested booting *BSD on them.

The only UN*X which NEEDS special documentation is LINUX!
Long live V7; Skip Solaris 2.x; FreeBSD IS the PC UN*X
