Instructions for enabling multiprocessor power performance support on Windows XP:
1.	Windows XP must have Service Pack 2 applied.
2.	Edit boot.ini file in the root directory to add the /usepmtimer option.
For example:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /usepmtimer

Instructions for enabling multiprocessor power performance support on Windows Server 2003:
1.	Windows Server 2003 must have Service Pack 1 applied.
2.	Edit boot.ini file in the root directory to add the /usepmtimer option.
For example:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows Server 2003" /fastdetect /usepmtimer

UNINSTALL INSTRUCTIONS:

1) Delete the "Oemx.inf" file from the "%windir%\inf" directory that contains the 
    header "amdk8".  This "Oemx.inf" should have been created from the previous

    CPU driver on the next system restart.

2) Right click on "My Computer" and select "Properties".
