I recently assembled a dual-processor system for kernel debugging. Installed
XP prof (checked version) came with msdn subscription (the very first XP
CDs). During installation I didn’t see any message or option that XP is
going to run on 2 processors. System properties just says Pentium 1.0 GHz
etc. Kernel debugger reports an MP kernel with (1 procs) etc.
Whats going on here ? Has anyone done a dual-processor XP installation ? How
do you do it ?
Apologies for this question being slightly off-topic on this list.
thanks for any comments,

How many processors does the BIOS detect? If it only shows 1 then I would
suspect a defect in the CPU, socket, or motherboard.

I have very similar results on my dual CPU machine. However, if I bring up
task manager it displays two CPU graphs and when I bring up device manager
and select Processors it lists both processors.
But Windbg reports MP kernel with 1 proc and system properties just says
Pentium III, etc.
I’m sure that my system is using both processors. I believe that system
properties is behaving as it should (it reports the processor and since they
are both the same it doesn’t need to list both). I don’t know why Windbg
reports 1 processor.

Thanks for sharing your experience. Though Bios detects 2 Pentium III I was
troubled to see windbg report MP kernel and 1 processor. Now I will go ahead
and verify through task manager.
Thanks much,

IIRC when the OS is booted and the WinDbg connection is established, only 1 CPU is running, the second one is started later after
boot drivers initialization or such.
Do you have 0: or 1: prefixes in WinDbg’s traces? If yes, then both CPUs are working.
