BIOS for the MSI MS-7263 desktop board, version 1.3, built around an Intel 945 chipset, with NEC noted in the name, likely the OEM build. MSI uses the MS-xxxx format for its board numbers, printed on the PCB. The ZIP is about 425 KB, consistent with an older, smaller flash chip. Use it to reprogram a corrupted BIOS with a programmer or socket flasher, after confirming the board version and chip size and saving the existing contents.
