Original BIOS dump for an Acer Aspire E1-422, 4.00 MB, read from a working machine according to the org tag. This size suits a 32 Mbit SPI flash chip. It is used to recover a board showing no display or boot loops caused by corrupted firmware, written with a programmer such as a CH341A. Check that the board and chip match, keep a backup of your own chip, and expect serial or system data from the donor unit to be present.
