Firmware dump for an HP Pavilion dm4, second copy, 4.00 MB in size with no file extension. The name gives no board number, revision or BIOS version. It can be treated as a raw binary and loaded into SPI programmer software to rewrite a corrupted BIOS chip on a dm4 that will not post. Confirm the flash chip on your board is 4 MB, back up its existing contents, and check the motherboard number, since dm4 models were sold with different boards.
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 →
