Raw binary BIOS dump for the HP Compaq Presario CQ42-401TU laptop, 2.00 MB in size. The TU suffix in HP model codes normally denotes an Intel-based configuration, but the name gives no board number or version. A file like this is written directly to the motherboard SPI flash with an external programmer when the existing firmware is corrupted. Before writing, back up the original chip, verify the chip is a 16 Mbit part so the image fits, and compare the motherboard revision with a known match, since CQ42 boards came in several variants.
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.
