Second copy of the Acer USOO BIOS dump, an 8 MB raw .bin file that suits a 64 Mbit SPI flash. The name gives no model, board number or firmware version, so the image should be matched to the board before use. It is paired with a status-register file saved from the same read. Compare it byte by byte with the first USOO copy to confirm the read was stable. Back up the original chip with a programmer before writing, and check that the chip capacity is 8 MB.
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 @biosfilebins. 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 →
