BIOS dump for a G31T-M desktop motherboard, version 1.0 according to the name, supplied as a 512 KB ROM file. The board name implies an Intel G31 chipset platform, but no manufacturer is stated. The size corresponds to a 4 Mbit flash chip, so the image can be written directly with an SPI programmer to revive a board that no longer posts. Make sure the board label and revision on your PCB read G31T-M 1.0, and back up the original chip before flashing, since similar-named boards from different vendors are not interchangeable.
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.
How to open a .rom file
A BIOS image as shipped by the vendor (commonly AMI) — often the BIOS region only, without descriptor or ME.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
