BIOS dump for a Wistron-designed board identified as HAMAR, board number 15080-1, with the additional part code 384-05A06-011 included in the name. The numeric pattern with a dash suffix is typical of Wistron motherboards used by Dell, Acer and others. Packed as a RAR archive of 4.08 MB, it is meant for reflashing the SPI BIOS chip with a programmer such as a CH341A. Confirm the board number on the PCB, read and save the original chip contents first, and make sure the image size matches the flash chip capacity.
