Donation, done. - Still hoping for sone help on the ASUS BIOS. 🤞

OK, it took me a while but here is the dumped and verified BIOS. (Details in post #7 of this thread)....

Hi everyone,

Have a ASUS GA503RS, it turns on, but after showing the logo the screen stays black. :-/
No success trying another screen, no external image either.

So after reading this thread and seeing similar issues being fixed with a BIOS flash, I would give this a try.

Have a CH341 programmer and can solder pretty well.

Details on the device:
ASUS GA503RS-LN055W
SN: N6NRCX076422248
MB: DANJPMB3AA0 REV:A

The BIOS chip is a Winbond 74M25JWEIO, my research shows it is a 1,8V powered chip, 256Mbit in size....
