Fixed BIOS image for the MSI H81M-P33 desktop motherboard, MSI project MS-7817, revision 1.2, packed as a 5.89 MB RAR. Marked as fixed, it is intended for reprogramming the board's SPI flash with an external programmer when the board will not POST after a failed update. MSI identifies boards by MS-xxxx codes printed on the PCB, so check this code and the revision before flashing. Always dump the original chip first, and verify the image matches the flash capacity.
