My ASUS P4B (i845, s.478) doesn't want to boot, I have seen it booting 2 times but all other tries ended up on code "C." according to my PCI diagnostic card:

It has a 1.7GHz S.478 P4 in it and a 256MB PC133 SDRAM stick. I've tried different RAM modules and graphic cards (both AGP x4 and PCI) but without much luck.
The CMOS is cleared, set to jumperfree/AUTO and the battery has been replaced.
