BIOS image for a G31T-M board, stated as version 1.0, 512 KB .rom. The name suggests an Intel G31 chipset micro-ATX motherboard, but the manufacturer is not given, and the 1.0 may mean either a PCB or a BIOS revision. Check the revision markings on the board before flashing. The size suits a 4 Mbit SPI or LPC flash, programmed with an external programmer. Back up the existing chip contents and verify the written image.
