I am in the process of rebuilding my XPSP2 Image to support Office 2007. As I am rebuilding this particular image I need to change the HAL configuration from ACPI Multiprocessor to ACPI Uniprocessor. I open device mgr and go to update the driver, however, I do not see the ACPI Uniprocessor HAL type listed under Models.

What is the best way to change the HAL type or should I use the UpdateUPHAL variable in my sysprep.inf?

Try using the ForceHALDetection=Yes entry in your sysprep.inf.

Paul,

Is it okay to build my master reference system with the ACPI MP, and then use the ForceHalDetection=Yes property in the sysprep.inf?

You should be able to do so. We use a single image that does the hal detect and it works on our uni & multi cpu systems.

The best way to chage the HAL on the computer before you sysprep it is to use DEVCON.EXE.

Are you using LTI to build your base image or are you doing it by hand. If you are using LTI, then you can just add an entry to your task sequence calls a VB Script. the VB Script should contain these three lines and be found in the same directory as a copy of DEVCON.exe

Set WshShell = WScript.CreateObject("WScript.Shell")
wshshell.Run "devcon sethwid @ROOT\ACPI_HAL\0000 := +acpipic_up !acpiapic_up", 1, true
wshshell.Run "devcon update c:\windows\inf\hal.inf acpipic_up", 1, true

This will downgrade the HAL to the most compatible one and you won;t have to remember to do it or mess around in the device manager.

Everything you might want to know about hal replacement can be found by googling with the terms "arwidmark" "HAL" and "devcon.exe"

Good luck!
