Perfect, thank you. And I think I've finally figured out how to find it in the file so I wont have to ask again.

you are welcome. Yep, comparing my file with your original file you can figure out where it is. Usually for this machine pass is in VSS2 Store/padding but you have to merge both files to open with UEFITool.

Hey guys, i would be grateful for any assistance with this board bios files.

Original Problem: ESC, CAPS and NUMLOCK lights on. Batt light flashing. Wont power on to Bios. Suspect it is corrupted.

What I tried: Replaced a noticeably hot ic - which seems to have cured the flashing amber batt light, as it is now white, but still no boot.
I also replaced the BQ chip just for the hell of it - no difference. Battery is Good. Bios battery is good. PSU is good.

I've attached dumps from #1 Bios: XMC 0H64AHIC + #2 Bios: 0H128AHIC (might be ...AHIG) see pics

I see a third bios chip, Winbond 25Q80DVNIG over near the USB-C ports, I uploaded that Bios too.

Could someone check my dumps please , or upload replacements I can use to flash back onto my board ?
