Abstract
A computer system contains a revision indicator which is stored in a protected special area of computer memory. The revision indicator specifies the revision of the hardware actually present in the system. The revision indicator data is presented by the computer during power up so that a user may be aware of the type and configuration of the computer system hardware. The revision indicator may be displayed by the computer system BIOS during power on self test (POST), for example. The memory storing the revision indicator is protected from erroneous or unauthorized change.
