Casper firmware image for the A15HC mainboard, revision 2.1, packed into a 1.84 MB 7z file. No GPU variant or chip type is given, so check whether your board is the integrated graphics or discrete version before using it. Technicians rely on such dumps to restore corrupted BIOS on a board that stays dark after power on. Confirm the revision silkscreen reads 2.1, back up the existing chip contents, and make sure the extracted file matches the capacity of the installed SPI flash.
