XP won't start - tried to disable ACPI

[Ryan]

Asus CUV4xD Dual Board and ONE P3 1.0Ghz
I had already installed XP and tried to disable ACPI to
improve the performance of my audio recording setup by
doing the following:
control panel>system>hardware>device manager> computer>
When I got here I clicked on ASCI Multiprocessor, went
through the wizard and picked a new device "MPS
Multiprocessor. I think this was a mistake and I should
have picked "standard PC". Anyways, now Windows won't
boot. At setup. it goes to a prompt that says "windows
won't start.... Either boot up in safe mode, safe mode
(with two other options), restart windows as is, configure
windows to work as it did before changes.
Well I tried all of these and nothing worked, it always
took me back to the same setup page.
How do I get back into windows and reconfigure the drivers
to fix this problem?
Help
Thanks
Ryan

Microsoft does not recommend that you change the HAL that is installed during
the Windows XP Setup process. When you change from the ACPI HAL to the
Standard PC HAL, you must reinstall the operating system, and ACPI functionality
is lost.

Ref: http://support.microsoft.com/default.aspx?scid=kb;en-us;315278&Product=winxp

The Windows XP CD is bootable and contains all the tools necessary
to partition and format your drive. Follow this procedure and allow
Windows XP to partition and format your drive:

NOTE: It would be best to physically disconnect all your peripheral hardware
devices, except the monitor, mouse and keyboard, before installing XP.

1. Open your BIOS and set your "CD Drive as the first bootable device".

2. Insert your Windows XP CD in the CD Drive and reboot your computer.
3. You'll see a message to boot to the CD....follow the instructions.
4. The setup menu will appear and you should elect to delete the existing
Windows partitions, then create a new partition, then format the primary
partition (preferably NTFS) and proceed to install Windows XP.

5. Clean Install Windows XP

6. ==> Immediately after installing Windows XP, turn on XP's Firewall.

7. After Windows XP is installed, visit the Windows Update website
and download the available "Critical Updates".

8. After installing the critical updates, be sure and visit the support website
of the manufacturer of the computer to download and install any
available Windows XP compatible drivers, such as video adapter
and audio drivers.

9. If you happen to run into any installation difficulties, use the following resources:

Carey,

couldn't a repair installation reinstate the correct HAL?

Ryan,

if you can find out which registry settings need to be changed
back, you can do it from another computer by moving the hard
disk there or from a second installation of Windows on another
hard disk or in another partition. For that you use
REGEDT32.EXE, load the hive temporarily into HKEY_USERS, change
the registry settings in the hive and resave it.

Unfortunately I don't know which registry settings control the
HAL selection, but perhaps you can find out.
