Help!! Why aren't my Dual Processors recognized?

[Guest]

I have Win 2000 Pro with SP#2 on my system which has 2 P3 700 MHz processors.
I have a Romtec Trios on this system (which enables me to boot up with 3
different Hard Drives and so 3 different OSs, 1 at a time). Win XP PRO
recognizes both processors, but Win 2000 Pro doesn't (although the help info
says it should).

Everything else works fine (although occasionally, when I boot up to Win 2K,
the display flickers as if at a low refresh rate despite it showing 75 Hz).

I don't want to go through the hassle of doing a clean re-install of the OS
(and thus all the programs I run on it).

Is there some way to get the existing install to recognize both CPUs?

Please let me know!

Whe you install 2000 Prof, did you have both CPU's installed at that
time or did you add the second one later? If you added one you might
have to install a different HAL (If I remember correctly).

Thanks for the reply.

Yes, I added the 2nd processor later (it is identical to the first one and
works well under Win XP Pro, just not in W2K)

I tried searching the article you mentioned
(3BA4317A-704F-4E29-8D54-E9E2CBCA079F), but could find nothing in the MS
Knowledge Base.

How do you instal a different "HAL" (and what is a "HAL"?)

Could you point me in the right direction here?

Thanks!

I don't think that you need to change HAL with W2k, you should be able
to get W2K to recognize the 2nd processor and use the correct HAL with
the Device Manager. Open the Device Manager and expand the "Computer"
branch. Double click the computer type and go to the driver tab and get
W2K to update the driver, that should get W2K to see the second processor.

PS HAL= Hardware Abstraction Layer. There is a hal.dll that Windows
uses to run the hardware. In the NT systems when you added a second
processor you usually had to change the hal.dll for the second processor
to work properly, W2K has done away with that. Or HAL was that computer
that didn't want to shut up in 2001: A Space Odyssey...

Thanks for helping me too. I've done so many of them, but they always
have the second CPU before I start. In the old days I had to run a cmd
that would update to SMP HAL, and with his description I guessed it
would be the same. I had not thought about just doing a UPDATE on the
COMPUTER ICON, so, the proper path would be - Device Manager, Expand the
workstation tree, Expand Computer, if it says ACPI Uniprocessor PC, then
right click that and "Scan for Hardware Changes" and if that fails to
detect it, then update drivers...

Yes, and if it doesn't work it may be because the BIOS isn't MPS aware
or enabled, if the BIOS can't see the second CPU Windows certainly wont
see it. You're welcome for the thank you.

Dave and John;

thanks so much for your help!

Dave, the article is spot-on (I could've used it yesterday, as it details
exactly what I had to do with John's guidence).

John, "you 'da man!!"

My PC works great now with both CPUs being used and all is well!! Life makes
sense again!!
