Acer Aspire 581T Option unlock

I am trying to unlock the RAID options on my Acer Aspire M3 581T. Can this be done ?

here is a link to the stock Bios http://global-download.acer.com/GDFiles/...ER&SC=PA_6

I am also interested in knowing how one goes about unlocking a bios so any advice is awesome ^__^

Thanks again
