Raw 8 MB BIOS binary named for an H81MX-D board, with no brand or revision given in the name. The H81 token points to a board built around that Intel chipset, and the 8 MB size fits a 64 Mbit SPI flash chip. Technicians write such raw images directly to the chip with a programmer to recover a board that does not boot. Because the vendor is not stated, verify the board model before flashing, back up the original chip, and confirm the chip is 8 MB.
