BIOS dump for an HP laptop built on Quanta board DAY12EMB6C0, revision C. Compressed as a 3.15 MB RAR, it is meant to be written to the SPI flash with an external programmer such as a CH341A when the original firmware is corrupt or the machine will not post. Quanta marks its boards with DA-prefixed codes ending in a revision letter, so compare the number on the PCB with this one. Read and save the existing chip contents first, and make sure the image size matches the flash capacity before writing.
