Optiplex 330 RAID 0 request

[dsmilees]

First off, I want to say hi! First post here, so I appologize if it's in the wrong place. I'm just really not sure where to start.
So, I got quite a few optiplex 330s as well as a dell poweredge 840 server from a place I used to work, and I ran a couple things on the poweredge 840 server for a while. Everything worked ok, but it was slow and loud and big and etc. Nothing is too intensive and I want to transfer the load and files to one of the optiplex 330s. Unfortunately, the BIOS is locked to only allow RAID 1.
I'm wondering if there is a way to unlock RAID 0. Hardware virtulization would also be nice, but that is very much optional and secondary compared to the RAID 0.
Here is a link to the BIOS download:
A11
Any advice or help would be greatly appreciated
Thanks,

Edit: I don't suppose there would be a way for me to flash the bios to the bios of the 755, since I'm PRETTY sure that the 755 supports RAID 0?
