Thanks for your help all but I think this one is beyond me as I cannot get an adequate connection to the chip with a SOIC clip (it's a GD25R256D in aWSON8 package so the pins are mostly underneath). Going to have a break and a think.

Ok cheers, I’ll keep looking. Found another flash chip by micronix, thought I’d solved it…nope 8Mbit/1MB…fml

Hi All,
Laptop: ASUS F15 TUF Dash FX517ZC-HN114W

Context: When I was out the house my partner hard shutdown laptop while BIOS was updating, so my son has no working laptop now. Also as a result I know the BIOS on the chip is messed up so I can’t extract it using the ch341a and use it to perform the method explained on site to modify an update downloaded from the ASUS website to get the BIN to flash.

If anyone can help with a BIOS BIN/ROM file for this laptop, I would be forever in your debt! Thanks if you can help!

Assuming it is less than 2MB as...

Hi All,

I am an electronic engineer by degree, a specialist systems engineer by trade and literally a nothing from a true hands on electronics person. You have to laugh.

computers I have used all the way from the BBC micro, Sinclair spectrum (48k), amiga 1200, then I moved onto versions pcs from the pentium 2 onwards (didn’t have the cash for anything earlier). Built a fair few of desktops, owned a number of laptops. Consoles I have worked from the mega drive (cd), Xbox, Xbox series X. Recently got a steam deck.
