BIOS file for the MSI B85M-E33 V2 motherboard, board number MS-7846, version D30, sized for a 16MB flash chip. Delivered in a RAR archive of roughly 7.6 MB. The V2 suffix marks a later revision of this model, so verify it matches the board on the bench, since MSI uses MS-7846 for many Haswell-era H81, B85, H87 and H97 boards. Dump and keep the original chip before flashing, and confirm the chip capacity is 16MB, as an image of the wrong size will not fit.
