BIOS dump for the Biostar A770E motherboard, revision 6.4, described as fully working, in a 707 KB ZIP. Desktop boards of this kind keep their firmware on a socketed or soldered SPI or LPC flash, which can be rewritten with a programmer when the board powers up but shows no display after a failed update. Read and keep the original chip contents first. Confirm the board revision and that the image size equals the chip capacity, otherwise the write will fail or the board will not boot.
