RAR archive with an 8 MB BIOS image for the Soyo Game X79 desktop board, also named SOYO X79 D3-AX, which suggests an Intel X79 chipset with DDR3 support. The 8 MB size indicates a 64 Mbit SPI flash chip. Desktop BIOS dumps like this are used to recover a board after a failed update or corruption, by programming the chip directly with a CH341A or a similar tool. Dump the existing chip first as a backup, and check the board model and flash capacity before writing.
