BIOS file for the Biostar H310MHG motherboard, board version 6.x, with 520 shown in the name, possibly a BIOS version, packed as a 5.60 MB RAR. The H310 name points to the Intel chipset of that model. Use it to reprogram the SPI BIOS chip with an external programmer when a flash update has failed or the board shows no display. Read the existing chip before erasing anything, check that the board version printed on the PCB is a 6.x revision, and verify the image matches the chip size.
