BIOS dump labelled for the HP Compaq 420 notebook, 2.00 MB in size and stored without an extension. The name provides no board number, revision or firmware version, so verify compatibility by comparing the motherboard number on the PCB with the source machine. A 2 MB image fits a 16 Mbit SPI flash chip and is written with a hardware programmer to restore a board with corrupted firmware. Always back up the existing chip before writing, since the original may hold serial and system data worth keeping.
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 @bios_laptop. 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 →
