Well.. There's no chance i'm going to update the BIOS - if you suggest the one on the motherboard.
The last time i updated the BIOS, my RAID5 stopped working / was reset and i lost it completely
So i'm stuck with the current BIOS which works just fine...
I'll update IRST when a newer version appears though, i guess that can't harm
I understand your concern regarding BIOS update. It is not strictly necessary but as best practice we recommend updating both Intel® Rapid Storage Technology and BIOS, so the RAID option ROM will be updated as well with a contemporary version (if it is indeed confirmed to be a feature updated with the newer BIOS version). This is just to let you know why we recommend it.
