Windows 7 upgrade worked but...

All was working just fine until I cloned it to save it to an external hard drive. Next time I opened it had a message that Windows had to be repaired. Windows ran a repair program which took a long time, then booted OK. Now I'm getting a message:
"Consider upgrading your computers BIOS. The Bios version on this computer does not match the specifications for the central processing unit. Contact your computer manufacturer or motherboard manufacturer for an updated version of BIOS for your computer's processor."
What does this mean? Haven't been able to talk to Parallels this morning. Using an Imac Intel with 10.6.6.

 

I forgot to mention that I'm using Build 6.0.11992. Windows 7 and my apps seem to be working fine; I was just concerned about that BIOS message in my previous post.
