Dual CPU with 2K?

[D26358]

I have one for you to chew on.

I recently installed W2K on a dual processor SM P6DBS. Prior to installation I upgraded the BIOS to the latest and went from a PII400 to dual PIII600 (yes, the 100 MHz non-coppermine variety, consecutive SN, chose MPS 1.4 setting).

I have to admit that I was pleasantly surprised. The W2K installation was probably the easiest that I have ever experienced with any MS product. Anyway, when it was finished I noticed that it had installed the uniprocessor HAL. Confused, I went into device manager and manually selected the comparable multiprocessor HAL. It restarted without incident. I verified that the multiprocessor HAL was installed. Everything seemed to be fine right down to the strange IRQs.

Upon closer inspection I found that task manager gave me a single trace even when trace for each cpu was selected. I poked around the registry, and as far as I can tell 2K still believes that it is a uniprocessor machine even though I have loaded (apparently successfully) the multiprocessor HAL. Even the environment variable states that the machine is a single processor machine.

Is this normal?
Is there a way to verify usage of a second cpu?
Is there something in addition to loading the mpu HAL that needs to be done to tell 2K it should be looking for/using multiple processors.

Thanks

I don't remember well anymore, but changing it to multiprocessor after the setup won't do the trick.

You will have to re-install w2k, but the part that I don't remember is how to make sure that it gets installed as a multiprocessor.

Maybe if you do a "fix the setup thingy" the multiprocessor will come up. Or maybe the setting is somewherelse. But one thing I'm sure. If you don't get two graphs then you dopn't have two cpus working.

The most sure way is to manually select "multiprocessor MPS (or ACPI)" during win2k setup. I went through the same experience as yours and I ended up reinstalling win2k to make sure that both of my CPUs were being utilized. If you don't mind, just reinstall win2k.

there is something that allows w2k to operate in SMP after installation with single processor.

i forget what it is called.

Wrong!! you can add SMP after install...

This basically covers what you already did, so there might be a problem with your install. Did you verify that the 2nd CPU functions correclty in Single CPU mode? Also, you can always do a repair to the existing install of win2k and then choose MultiCPU HAL there.

Thanks...I figured that this would be the next step. Just didn't want to poke around inside if I didn't have to. It's getting pretty crowded in there.
