BIOS image for the Intel DX58SO desktop motherboard, the X58 chipset board for LGA1366 processors, with the name also carrying the common misspelling DX58S0 and an OK mark indicating a working dump. The 921 KB RAR holds the firmware used to recover a board that fails to post after a bad update. Program the SPI flash with an external programmer, read and save the original chip first, and compare the image size with the chip capacity, since a file that does not match it will not fit correctly.
