1 MB BIOS binary named only CQ62, suggesting the Compaq Presario CQ62 series, with no specific model suffix or board number in the name. The size corresponds to an 8 Mbit SPI flash chip. Since CQ62 notebooks were made on more than one mainboard, compare the PCB code with identifying strings inside the image before programming. Dump and save the original contents first with an external programmer, then flash and verify, making sure the chip capacity equals 1 MB.
