I own a Compaq Deskpro EX 1.0 with Bios Ver 2.04 (the latest available) I recently laid hands on a Intel 1266/512/1.45V Tualatin processor wich works on the mainboard but the error code 1801 is given.
Windows XP pro recognizes the processor, CPU-Z also reports the right speed an FSB but every restart shows 1801 eroor in the post, micro code patch required.

Any one got a clue?
