Hi according to HP memo see the following answer hope it help:

DESCRIPTION After installing a different system board or processor in systems described in the "Scope," the systems may halt during POST and display an 1801 Microcode Patch Error with a prompt to press the F1 key to continue.
NOTE Pressing the F1 key will allow the system to continue. However, processor performance may not be optimized and the error will repeat each time the system is restarted. HP recommends that the microcode be updated to ensure optimum compatibility and performance.

I bought a Compaq Computer, 2.0Ghz, 256MB, 20GB for my College project. When i put the power on, it restarts almost immediately (so many times repeatedly). Then after such reboots, it successfully brings a message "1801 - Microcode Patch Error" and a F1-Boot directive.
