Firmware package for the Acer One 10 tablet-convertible, whose board is identified as T1000B-MB-PCB-V4.0, packed in a RAR archive of roughly 3 MB. The name does not say which chip the image is for or whether the Management Engine area was cleaned, so open the archive and read any included notes. A dump like this is usually written to the SPI flash with a programmer such as a CH341A to recover a board that will not boot. Read and save the original chip contents first, and check that the image size matches the flash capacity and that the PCB carries version 4.0.
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 @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
