I also have this problem; on Acer computers there is no way to access a RAID or RST specific portion of the BIOS--one does not exist. Additionally, converting to GPT and reinstalling Windows does -NOT- fix the problem--RST locks down permissions on the disk. While you can use DISKPART or any other utility to change the READ ONLY attribute of the disk to NO, the CURRENT READ ONLY attribute will NOT change to NO (it always remains YES), which means that even if you CLEAN the disk or otherwise destroy the volume occupying the physical disk, you cannot create a properly formatted volume on the disk because it is READ ONLY. This permission issue persists through Windows reinstallation (three of them, in fact).
We need a way, through Intel RST, to have RST surrender permissions, disk hiding, and all of the other lockdown mechanisms it uses on the disks.
