BIOS image named CQSO, 2.00 MB in .bin format. The name is cryptic and gives no clear model, board number or version, so treat its origin with caution. A 2 MB image fits a 16 Mbit SPI flash chip, written with an external programmer when a laptop will not post because of corrupted firmware. Before using it, identify the target board number on the PCB and make sure it matches the machine this dump came from, back up the original chip, and confirm the chip capacity is 16 Mbit.
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.
How to open a .bin file
A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
