I think it would have to be thoroughly tested on each specific motherboard before they go overriding what the BIOS is trying to tell the OS and enabling it anyway for everybody. That's probably the reason why the mobo manuf. didn't bother enabling it in the BIOS to begin with.... The manuf. may have never thoroughly tested it.... Or perhaps they just felt that setting it in the BIOS was redundant if the drivers enforced it.
No announcement yet.
