BIOS image for the ASUS K46CM laptop mainboard, revision 2.0, with the name pointing to a 25Q64 SPI flash chip. A 25Q64 is a 64-megabit part, which matches the 8 MB size of the image, so it should fit the chip one to one. Technicians use a dump like this to recover a board that will not post after a failed update or a corrupted chip, writing it with a CH341A or similar programmer. Confirm that rev 2.0 is printed on your PCB and save the original contents before erasing anything.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @abgm_manutencao_bios. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
