A RAR archive with BIOS firmware for the ASRock H87M desktop board, labelled as an 8 MB image. The archive size suggests it may hold more than one file, possibly several versions or backups, so review the contents after extraction. ASRock boards usually take their BIOS from a socketed or soldered SPI chip, which a CH341A-style programmer can rewrite when the board will not POST. Confirm the chip is 8 MB and read the original contents before flashing.
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.
