BIOS archive for the JW A790GXT Extreme desktop motherboard, a board from the JW brand whose name points to the AMD 790GX chipset. The 775 KB RAR likely holds one compressed firmware image. No version or revision is stated, so compare the model printed on the PCB and, if possible, the original BIOS label before use. Such dumps are written with an external programmer to revive boards with corrupted firmware. Save the existing chip contents first and check that image size matches the flash chip capacity.
