BIOS image for a Compaq CQ23 laptop, with the board marked 71R-H14BT4-T830 and an 8 MB flash size stated in the name. The RAR is 3.17 MB because compression shrinks the padded image. Use it to reflash the SPI chip with a programmer when the machine powers on without display or after a bad BIOS update. Verify the board marking on the PCB before writing, save the original chip contents first, and check the extracted file is exactly 8 MB so it fits the chip.
