How to set two processors under windows 2000?

[prevailing]

Ok, so I have windows 2000 installed and I booted up a chess program to see how my system ran, since I just got everything set up today. I have a dual pentium 3-1000mhz system, but programs see only one processor. What have I done wrong?

Did you have Windows 2000 installed before you went to the second processor motherboard? Basically Windows 2000 is running on another Hardware Abstraction Layer (HAL) if you installed before. The easiest way is to reinstall from what I hear.

Whenever you make drastic system changes such as this, it's usually a good idea to reinstall the OS. Another case would be changing the mobo.

I installed an upgrade version of windows2000 from windows98... I used CPUID and I can info on both cpu's, but ti doesnt say that it uses thekm under any apps I run... any help on this?

You can tell if Win2000 is using both CPUs by pressing Crtl-Shift-Esc. This will bring up the task manager. Then flip over to the Performance tab and look at the meter at the top. If there are 2 meters, side-by-side, under "CPU Usage History", then Win2K is using SMP and you're just fine. If there is only one, you're still using the uniprocessor HAL. It is possible to "upgrade" to the SMP HAL without reinstalling, but I don't recommend that.

If you have only one graph, check the view -> CPU history -> pull down menu and make sure it doesn't say &quot;one graph, all CPUs&quot; to make sure you're running one or two CPUs.

You don't have to reinstall with 2000. Open Device Manager, expand Computer, make note of the listing under Computer. It will probably say something about ACPI. If it already indicates multiprocessor, then your set. Otherwise, select Properties > Driver Tab > Update Driver > Next (in update wizard) > Display list of known drivers.. > Next > select Show all hardware of this device class. > Select the appropriate multiprocessor driver and follow the prompts.
