BIOS .bin 2.00 MB Shared

Main BIOS dump for the HP Compaq 6735s business laptop, 2.00 MB, suitable for a 16 Mbit SPI flash chip. A separate 1 KB file for the same model appears to cover a small companion chip. Program this image with an external programmer when the board is dead or stuck after firmware corruption. The name gives no board number, so check the motherboard markings first. Save a full read of the existing chip, as it may contain the serial number and other system data, before erasing and writing.

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.
