Firmware dump for the ASUS PU451LD notebook, motherboard revision 2.1, intended for a 16 MB flash chip and archived as RAR. Unlike the revision 2.0 file, the name carries no tested or working mark, so treat it with some care. Technicians program such images with a CH341A or similar tool when the laptop shows no POST or loops on power. Compare the revision printed on the board, verify the image is exactly 16 MB, and keep a copy of the original chip read before erasing anything.
