BIOS May Report Error with Certain Processor

Article Summary: This article is intended to walk users through fixing a System does not support the installed Processor error message on the Optiplex 330 or Optiplex 755.

When powering on an Optiplex 330 or an Optiplex 755, the following error message may appear: System does not support the installed Processor. Please consult your computer documentation for more information. This error message only occurs during the Power-On-Self-Test (POST) sequence and may not be noticeable since the computer will automatically go to next screen within 1 second.

The message is displayed because the code to check Central Processing Unit (CPU) platform ID in the BIOS is incorrect. Dell has released an updated BIOS with the correct code to fix the error.
