HP desktop motherboard BIOS for board IPISB-CH, revision 1.04, sized for an 8MB flash chip, archived as a 2.03 MB RAR. A technician uses such an image to recover a system that no longer posts after a failed update or corrupted firmware, writing it to the SPI chip with a programmer such as CH341A. Read and keep a backup of the original chip before erasing. Check that the extracted image is exactly 8 MB and that the board marking and revision match, because a wrong-size image will not fit.
