1801 - Microcode Update Error
Missing or Invalid Processor Microcode…. This error comes on the POST....
However the machine boots fine and works fine after you press F1… the processor (as far as I can tell) is functional….
I tried a Bios upgrade.. According to HP's site… but no doing…. Any other ideas I may try to get rid

You need to update your Intel processor microcode patch. This can be updated independently of the system BIOS. The latest microcode update for the d530 786B2:
If you use this and still see the POST error message, please go into F10 Setup under System Properties and report the detailed description, including the stepping, of the processor in your system.
Hope this helps,

I've just replaced my P4 2.8 non HT CPU to a HT CPU in my D530.
I've upgraded the BIOS to 2.50 and installed the latest micro code but still am getting the 1801 error.
The machine works perfectly if I press F1 to boot. The processor stepping is F25.
Is there a way to ignore these errors (Award BIOSes etc have ignore on failure settings) or is there a microcode update which has F25 in it?

Hello!The solution to your problem requires the following :
A formatted Floppy Disk and an Internet connection.
First of all launch the google search engine and write your PC model for example:
"Hp Compaq d530 small factor form Desktop Pc"
and then ask google for the latest Microcode Update available for your PC.For most of d530 models the latest Microcode Update is "Version 1.09".Download it and then launch the downloaded setup and install the Latest Microcode update files to any drive.Copy the files extracted by the setup and simply paste them in a new floppy drive.Now reboot your system and set Floppy Drive as your first bootable device.Finally restart your PC,a setup will automatically begin to start,follow the instruction and upgrade your Microcode to Version 1.09.Hope it will solve your problem.For furthur assistance contact me,my Yahoo ID is firstname.lastname@example.org
