Updated BIOS Marvell Raid 1 Drives no longer recognized

I recently updated the bios for my Intel motherboard.  I had two sets of raid drives.  One running off or the Intel RAID controller and 1 running off of the Marvell.  After the update the drives in the Intel controller work fine.  The drives connected to the Marvell raid controller are not recognized. The Marvell drives were configured as Raid 1.  I can access the Marvell controller through the BIOS set up and the drives show up there, but there is no RAID configured.  If I choose to configure a RAID, I get the alert that the file structure on the discs could be lost.  I don't want to lose my data.  (I neglected to back it up!)  I cannot access either disc even if I plugged into a non-raid slot.  My questions are:
1.  Can I reconfigure the raid without losing anything?
2.  If I reconfigure the raid and lose some of the file structure will I still be able to recover most of my data?
3.  Is there another way to read from either of the RAID 1 discs from a non-raid configuration?

I don't know that controller. Most of them should be able to keep the info on the disks without destroying the data though. For safety I would still connect one of the disks to another non raid controller, and run getdataback on it, then register the tool to copy your data off.
