BIOS dump for the AD2550B-ITX mini-ITX motherboard, marked tested, as a 2 MB raw binary. The size indicates a 2 MB (16 Mbit) SPI flash chip, so the image should be written to a chip of that capacity. Technicians use such a file to recover a board that no longer posts after corrupted firmware, programming the chip with a CH341A or similar tool, either in-circuit with a clip or after desoldering. Save a copy of the original chip contents first and confirm the exact board model printed on the PCB.
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 @CLRINDORE. Enginerys does not host this file.
How to open a .bin file
A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
