On A00 PWA brds, this was connected up to 5V for PCI 2.1 support.

On A01 PWA brds, these resistors were connected up to 3.3V for PCI 2.3 support.
A01 PWA brds used A00 PWB and rework

On A02 PWA brds, these resistors were changed to make no issues with PCI 2.3 add-in cards
On A02 brds, these resistors were changed to 22k 5%, Dell P/N 30423.
