BIOS firmware archive for an HP Compaq A900 series 17-inch notebook in its Intel-platform variant, packed as a 628 KB RAR. The name gives no board number or BIOS version, so confirm the motherboard model printed on the PCB before use. Extract the image and write it to the SPI flash chip with a hardware programmer such as a CH341A or RT809. Read and save the original chip contents first, and verify that the image size matches the chip capacity, since a mismatched dump will not fit or boot.
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 @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
