Desktop BIOS for a board marked G41T-TM, an Intel G41 chipset motherboard, with 100104S in the name, which may be a build date or version code. The 546 KB RAR presumably holds a single flash image for the board's BIOS chip. Use it to recover from a corrupted BIOS by programming the chip out of circuit or with a clip. Back up the existing contents first, and confirm the model printed on the PCB is G41T-TM. Make sure the image size matches the chip, since a mismatched dump will not fit.
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.
