1801 error microcode patch. invalid or unknown bios rom to support the new proccessor.started after changing hard disk. trying by pressing f1


My published guide may re leave you of your troubles, it is entitled My Computer is not turning on!!! Is it dead!!! No POST!!!

Seems as if the BIOS has become corrupted, the BIOS may need to be flashed. Also try to get the system to original hardware state, ie when you had no problems.
There is a business called Bad Flash Click here to visit their site, this may get your system going again or you may feel it better to either replace the faulty component. Alternatively you could purchase a new PC.

Happy testing

1801 Microcode Patch Error


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.
