HP 15 BIOS image, 4.00 MB without an extension, described in its name only as AMD and china, so it targets an AMD-based variant but the exact board and revision are not given. The (2) suffix marks it as a second copy. A 4 MB file fits a 32 Mbit SPI flash device and is typically programmed with a CH341A or similar tool. Match the chip size and the board number printed on the motherboard before use, and keep a verified backup of the original firmware in case the dump proves incompatible.
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 @biosfilebins. 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 →
