Kindly help fix bios.
No video after CPU Phase DRMOS shorted, (power rail fixed and voltage present).
I already tried #23 file and no video.

I have a DA0ZYPMBAF0 rev F motherboard on the bench. It will react to power button and bring up some power rails. Everything seems fine just MAINON comes on and off in around 0.5secs. I'm kind of stuck at this point. Seems like a missing power rail, however the MAINON timeout seems too rapid for that. HWPG is like an ALL_SYS_PWGD, but this is pulled up by a switched +3V rail (again this doesn't come on long on enough to see what is happening)!

EC code looks fine after dumping the ITE. Compared it to what's in the BIOS (from 1000000h) and pretty much the same. I also erased the ITE and it auto-programmed from BIOS on the next power on too, no change in the fault. BIOS also looks ok however I do get this error in MEAnalyzer (but other dumps here do too).

"Error: Detected MFS Low Level File 269 which has not been parsed!"

The only thing I see is brief flash of heat on the PCH via thermal camera but nothing I would consider abnormal. I am getting SUSC# and SUSB# transitions from the PCH so I'm thinking that is working in some fashion. No power sequence diagram in the schematic unfortunately.

Here is the dump from this machine if someone could give me a clean one.
