Acer Extensa 4630Z BIOS backup packed as a RAR archive of 816 KB, labelled as an onboard original (asli means original in Indonesian), meaning it was read from a working board rather than built from a vendor update. Technicians use such a dump to restore a corrupted or locked SPI flash with a programmer such as a CH341A. Extract it, compare the image size with the capacity of the chip on your board, and always save the existing chip contents before writing anything, since serial and configuration data differ between units.
