MSI H81M-P33 V2 (MS-7846) MS-7846.A30

BIOS .rar 6.00 MB Shared

BIOS dump for the MSI H81M-P33 V2 motherboard on the MS-7846 platform, firmware version A30, packaged as a 6 MB RAR. No flash size is given, so check the extracted image against the chip capacity before writing. A file like this is used to reprogram the SPI chip when a corrupted BIOS leaves the board without POST. MSI uses MS-7846 across numerous micro-ATX models, so verify the model and V2 revision on the PCB, and save the original contents before flashing.
