BIOS package for the Acer Aspire One 752, named AO752, in a 915 KB RAR. The name identifies only the model, so the BIOS version, motherboard code and flash capacity need checking inside the archive and on the board. Raw chip images like this are commonly used to revive units with no display after a bad update. Flash with an SPI programmer such as a CH341A, keep a read of the original chip, and check that the image size equals the chip size.
