Hi,
I have an Intel 7505VB2 dual Xeon motherboard with 2x2.66GHz CPUs, Redhat
9.0 and self-compiled 2.4.23 kernel. Interestingly, I see only one CPU
with e.g. "top", or cat /proc/cpuinfo, etc.
I have to tell though that I installed this system by cloning the disk of
another PC, which is running a single processor; then booting in the dual
processor computer from the cloned disk (with a bootfloppy), and then
recompiling the kernel (and rebooting to the new SMP enabled kernel).
Seems to me that this is not enough, and I might have missed something.
Any advice would be welcome.
Thanks
Gaspar

This looks like you have 2 physical processors. Perhaps you don't have
hyperthreading enabled, i presume you want 4 logical processors. Try the
"acpi=ht" kernel parameter.

Sorry i mis-parsed your email in my haste. Could you try the following
