I would like to flash my P35-DS4 motherboard BIOS F4 to F5G but would like to know first whether it will affect my OS especially my Windows is sit in RAID volume before I proceed.
I am new in this area, hope expert may help to answer my question. Will I lost my data? Is my windows still remain accessible after flash the new bios? Do I need to reinstall my Window or rebuilt my RAID array after motherboard bios update?

Thanks
