What's the other SMP (not the default one) to install w/ W2K?

[db]

There's another way W2K handles SMP other than the default SMP installation--but I can't remember what it is called.
And I need to install it instead of the default SMP for a new clean install. How do I ensure that IT and not the default SMP gets installed?
Thanks

(My old mobo supposedly plays much nicer with the "other" version of SMP)

wha chu talkin bout, willis?

I assume that you are trying to say that your system does not work too well with the ACPI Multi Processor HAL.

In that case, you need to select the MPS Multiprocessor PC.

During the first phase of Setup, at the Setup is inspecting your computer's hardware configuration screen, press the F5 key. You will be given a list of HALs; just select the one I told you above.

Ha, if I could explain it any better, I prolly wouldn't have to ask.
As little as I remember, a normal default install of Win2000 pro will detect a dual processor machine and install automatically.
However, there is supposedly a non-default install which uses something other than (or in addition to?) "SMP" to enable and handle multi processing.
I can't remember what is...

That sounds like it. Thanks AndyHui!

(A note in case anybody else looking into this procedure)

I was only given these choices:
-standard PC
-standard PC w/ c-step i486
-SGI mp
-other (if have device support disk form manufacturer)

So perhaps fact that I have dual celerys instead of Pentiums is why I was given the above choices.

I only found MPS multiprocessor in WinXP..

If you go to Device Manager, pick the "Computer" device, and you probably will see "MPS Multiprocessor PC". Double-click that, and then click "Update Driver", then "Next", then "Display a list of the known drivers....", then "Next", then "Show all hardware of this device class", and you will see a list of standard computer types. I think you can just pick the one you want right there, and should be set. I think

edit: I have dual celeries and Windows 2000 Advanced Server. It shows as MPS Multiprocessor PC at the moment. I'm gonna change it to ACPI Multiprocessor PC and see what happens!

db - IIRC, the list of possible PC configurations is scrooled all the way to the end when you get it. You need to scroll up and then you'd see the other SMP configurations.

Oops, bad idea! Now I get to reinstall the OS. Sh!t.

If ACPI is enabled in your BIOS when you install Windows, you should automatically get the ACPI Multiprocessor HAL on a fresh install. If ACPI is not enabled in your BIOS, you should get the MPS Multiprocessor HAL.

For the record, the only type of multiprocessing support W2K offers is symmetric multiprocessing (SMP). There are other multiproc architectures, but W2K does not support them.

What you're talking about in this thread is which HAL setup chooses for the computer. There are (I believe) six HALs that ship with W2K. They are:

-Single Proc (ACPI and non-ACPI)
-Uniproc (ACPI and non-ACPI)
-Multiproc (ACPI and non-ACPI)

Single proc is used on mobos that only support one proc.

Uniproc is used on mobos that support multiproc that have one proc installed.

Multiproc is pretty self-explanatory.

The decision to use ACPI or non-ACPI version is based on a number of factors, but in the end boils down (more or less) to what the BIOS supports. If the BIOS supports ACPI, the ACPI HAL is chosen by default.

In general, unless you know for a fact that the installer is choosing the wrong HAL for some reason, or you're running custom hardware that has an OEM HAL, it's best to let setup choose the HAL for you.

You *can* choose to install the non-ACPI HAL at install time if you'd like, but as you've discovere, you CAN'T change from ACPI to non-ACPI (or vice versa) after the OS is installed.
