BIOS archive for the Gigabyte GA-J1800M-D3P, a micro-ATX desktop board with an onboard Intel Celeron J1800 processor. The RAR of about 3.4 MB holds the firmware image for the board's SPI flash. Technicians use it to recover a board stuck with corrupted firmware by writing it with an external programmer. Gigabyte boards may use dual BIOS chips, so identify which chip you are writing, read and save the original first, and make sure image size matches chip capacity.
