MSI has announced that it will be rolling out the AMD AGESA 1.0.0.6 BIOS firmware on its existing AMD 300/400 series motherboards. The new firmware includes a range of optimizations, support features, and fixes for compatibility issues with certain USB sound cards and graphics cards.

While AMD has reset its BIOS firmware naming scheme, now starting from 1.0.0.0 (V2), board makers will still be releasing V1 BIOS firmware on older 300 and 400 series motherboards. MSI today released the AGESA ComboPI 1.0.0.6 BIOS firmware for a total of 37 motherboards that include its A320, B450, and X470 motherboards.
