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.
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
driver installation, and must be deleted to prevent the OS from re-installing the
CPU driver on the next system restart.
