Main BIOS dump, 4.00 MB, for a Sony VAIO motherboard MBX-235 fitted with an Nvidia N11P-GS-A1 GPU and an Intel Core i7 processor, according to the name, which also carries an f13 tag. It pairs with a smaller 128 KB file of the same naming. Technicians use such an image to recover a board with corrupted firmware by writing the SPI chip directly with a programmer such as a CH341A or RT809. Check the Sony MBX-235 marking on the board, confirm a 4 MB (32 Mbit) flash chip, and save the original read first.
