They're really nice!

If you get one for free, mail me :-)

Hmm.. That's a NetBSD Mailing List, but I'm more familiar with FreeBSD.
I have heard good things about that.
And just enable the following things in the kernel:

options	SMP
options APIC (If it is APIC Compliant)

If that doesn't work you can try out defining the number of CPUs bussess
If it works, send me the dmesg output, please.

I don't know. I just know that FreeBSD runs on Proliants with SMP. Don't
ask me which ones, but Compaq has them in their testdrive project
