BIOS archive for a Q87H3-AM desktop motherboard, a name that suggests the Intel Q87 chipset. The 3.12 MB RAR presumably holds a flash image for the board's SPI chip. Technicians use these dumps to recover boards that power on without video or that were bricked by an interrupted update, writing the image with a programmer such as a CH341A. Before flashing, read and keep the original chip contents, confirm the board model on the PCB, and make sure the binary size matches the chip capacity.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
