Firmware image for the MSI H81M-P32L, a variant on the MS-7846 board design, carrying BIOS release MS-7846.190 and intended for an 8MB SPI flash. Packed as a ZIP archive of about 6 MB. Technicians use such dumps to recover a board that will not POST after a failed update or corrupted BIOS by writing the chip with a CH341A-type programmer. Because MSI shares MS-7846 between several chipset models, check the silkscreen model name and back up the existing chip contents first.

How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
