Ok - just tried that, but I still see only two processors in cpuinfo
Any ideas?

Does your system BIOS have an option to enable/disable HT support? If it
does, make sure it is enabled.
I would have expected to see 4 ioapics, but hmm, I don't really know.

Processors are LOCAL apics, not IO APICS.
Your system may have 4 IO APICs but that is a coincidence. There should
have been some LAPIC lines, and these are the processors.

All the obvious stuff like bios is correct :)
The 2.4 kernel works fine; 4 cpus detected and displayed in /proc/cpuinfo.
2.5 has never worked properly yet with this m/b; A shame since it's asus
top of the range dual xeon server board, the PR-DLS.
The 3 io-apics are indeed strange. I'm hoping Andrew Grover might have
some ideas...?
Andrew Walrond
I have 4 cpu's! Hoorah!
Either I made stupid mistake yesterday, or changes got in a bk pull this
morning (I noticed apic.c had changed) solved it.
Either way, the problem is resolved - thanks!
