BIOS for the ASRock H81M-ITX mini-ITX desktop motherboard, in a 10.5 MB RAR containing a 4MB image for a 32 Mbit SPI chip. No version or ME state is given in the name. Desktop boards often have a socketed or easily clipped flash, so recovery with a CH341A or similar programmer is straightforward. Back up the existing chip, confirm the image inside the archive matches the chip capacity, and verify after writing. Clear CMOS before the first boot so stale settings do not interfere.
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.
