Issue resolved. I downloaded ReclaiMe Free Raid Recovery which is free RAID configuration analysis/evaluation software. It identified all of the RAID parameters and is set to transfer the settings to recovery software applications, theirs and others. I purchased theirs, ReclaiMe, and the interface between the two apps went easily and I was able to recover and copy all of the files to a new drive.
Very user friendly and almost hands free operation .
Lessons learned are to be prepared for the unexpected when a bios update is installed, and probably the best advice is to purchase a raid controller card which isolates the raid array from any bios/motherboard related issues and would be portable to a new or different system.
