You were very, very lucky this worked at all. You say "plain old Athlon", not "Athlon XP". This implies Thunderbird, which really didn't support SMP and I'm very surprised it worked at all in the Asus board. Are you sure you don't mean "Athlon XP" (Palomino or newer)? The reason your BIOS is complaining is that non-MP Athlon's aren't guaranteed to work in an SMP configuration. If you sampled 10 Athlon XP's of them, I guaranteed some of them wouldn't work in SMP mode. Athlon MP CPU's are fully tested, QA'ed, and certified to run *reliably* in SMP mode and configurations. If AMD didn't have these checks put into the BIOS, and you used two XP's that wouldn't work together you'd call AMD CPU's "crap" and be all pissed.
