BIOS image for an X58 chipset motherboard identified as MEN53-109A-3P, stored on an MX25L8005 flash chip, in a 513 KB RAR archive. The MX25L8005 is a Macronix 8 Mbit (1 MB) SPI flash, so the extracted file should match that capacity. Typical use is recovering a board left unbootable after a failed flash, either in-circuit or with the chip removed and written in a programmer such as a CH341A. Read and keep the original contents first, then verify the written data.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
