Firmware for an M4A88T-M motherboard at board revision 2.00G, supplied as an 811 KB rar, with no BIOS version stated in the name. The revision code is the one printed on the PCB, so match it before use. Technicians use such images to recover a board with a corrupted BIOS by writing the SPI flash with an external programmer. Read and save the chip already fitted first, and confirm the extracted image size is identical to the chip capacity, or the write 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.
