Acer Aspire 7250G firmware at version 1.05, with the AAB70 code given in the name, packed as a 1.03 MB ZIP archive.

Technicians use such images to rewrite the SPI BIOS chip when a notebook will not POST. Confirm the board identity, take a complete backup of the current chip with a programmer, and verify the binary length matches the installed flash chip before writing.
