BIOS image for a Biostar A320MH motherboard, board version 6.x, with A32ASC01 appearing as the firmware identifier in the name. The 16 MB size matches a 128 Mbit SPI flash chip, typical for AMD A320 boards. The .bss extension is the format Biostar uses for its BIOS files. Technicians write such an image with a CH341A or similar programmer to revive a board with corrupted firmware. Confirm the board version printed on the PCB, save a backup of the existing chip first, and make sure the image size matches the flash chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @oficinacomputadores. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
