BIOS image for the ASUS K54C with no file extension, 4 MB in size. The name gives no revision or status, but the size points to a full dump of a 32 Mbit SPI flash chip. Programmer software such as the ones used with CH341A or RT809H can load it as raw binary. Before writing, check that it is not blank by viewing it in a hex editor, compare your board revision with the source, and save the original chip contents.
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 →
