BIOS archive for the Biostar TA790GXB A2+ desktop board, listed under ECS, roughly 730 KB compressed. The A2+ suffix separates this model from the plain TA790GXB and the TA790GXB3, so check the exact model printed on the board before flashing. The image serves to recover a dead or bricked board by reprogramming its flash chip. Extract the archive, confirm the file size equals the chip capacity, and save the existing contents with your programmer first so you can roll back if needed.
