BIOS .zip 705 KB Shared

BIOS package for a 945PT-A21333 desktop board with PCB version 1.x, based on the Intel 945 chipset, 705 KB in size. The name gives no brand or BIOS version, and a larger file with nearly the same name also exists, so compare their contents to see which suits your board. Technicians use these images to reprogram a corrupted flash chip with a programmer. Read and save the existing chip, verify the PCB marking, and make sure the image size fits the chip.
