BIOS dump for a laptop identified by the model string 7250g-e453g50mikk, which matches the Acer Aspire 7250G naming, with the code AAB70 and Rev 2, as a 2.00 MB BIN. The name does not explain AAB70, so treat it as an identifier to compare. At exactly 2 MB the image fits a 16 Mbit SPI flash and can be written directly with a programmer. Technicians use it when the laptop will not post. Check the board revision on the PCB, confirm the chip size, and back up the original contents first.
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 @efibios. 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 →
