I just set up a new system using the P5B Plus and a q6600 processor. It appears that it is only using one of the cores on the processor. Windows task manager only shows one window. The system runs slower than the old 2.6G processor it was supposed to replace. Is the processor bad or did I do something stupid in the setup or bios? I did upgrade to the new bios 604, which didn't help.
Thanks,

The first thing I'd check - go to Device Manager, check the "Computer" entry.
The subentry underneath it is the HAL or Hardware Abstraction Layer.
For the more trivial HAL changes, you change the "Driver" for the HAL
entry. That process is described in an example here:

If the computer was using a HAL of "Standard PC", you'd be in a real
mess. If, on the other hand, you're at "ACPI Uniprocessor PC", it
is going to be five minutes work to update the driver so that it
reads "ACPI Multiprocessor PC". Once you reboot, Task Manager should
start to show all your cores.
In the BIOS, there has to be support for ACPI. Occasionally, a bad
BIOS design will upset the repair install you are doing, and
bugger up the HAL entry. You have to make sure, that all the necessary
features have been turned on in the BIOS, before doing the repair
install. Otherwise, you'll need to fix Suspend To RAM with
programs like Microsoft's "dumppo", and mess around with
HAL changes and the like.
HTH,
Paul
