And follow the instructions here to upgrade the BIOS. I suggest using their instructions as they will be far more accurate than mine for this specific system and BIOS update.
The 1801 error is defined as: Missing or invalid Processor Microcode Patch.
Resolved by: Applying a new ROM BIOS to support the processor stepping. In other words, you need a BIOS upgrade. Contact your BIOS vendor and get support for your new processor.

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.
