BIOS firmware archive for the Zebronics-style ZX-G31LM desktop motherboard, revision 4.0 as stated in the name. The board name points to the Intel G31 chipset family used in budget LGA775 systems. The 487 KB zip most likely holds a small SPI image of the size typical for boards of that era. Use it to recover a board that fails to POST after a corrupted update, writing it with a CH341A or similar programmer. Confirm the PCB is marked v4.0, since images from other revisions may not boot, and read the original chip before erasing it.
