When setting a Universally Unique Identifier (UUID) on a desktop system, the value that appears in the Setup screen appears to be different. The UUID may also be reported in the standard UUID format by Preboot eXecution Environment (PXE) or applications, and differ from what is on the box label and BIOS setup screen.

- ThinkStation E20
- ThinkCentre M58, M58p, A63, A70z, M90, M90p

(All future systems will follow this format)
