BIOS dump for the Foxconn 45CM-S desktop motherboard, read from a Winbond W25X40 chip, which is a 4 Mbit (512 KB) SPI flash. The date and time stamp 2015-07-22 20:22:49 in the name looks like the moment the programmer saved the read. The zip is 452 KB. Write it back with a programmer that supports the W25X40 to revive a board with corrupted firmware. Keep a backup of your own chip before flashing and confirm that the board model matches 45CM-S.
