BIOS firmware for the ZX-A88M2+ desktop motherboard, version 1.0, in a 1.63 MB RAR archive. The A88 part of the name suggests an AMD A88 chipset board, though the file name does not confirm this. Use the image to restore a board that will not post or has a corrupted flash, typically by writing the SPI chip with a CH341A or similar programmer. Read and keep the original chip contents first, and check that the extracted image matches the chip capacity.
