What is the Upgrade BIOS version

Hello,

can you please, help me find out what is the latest upgrade for Phoenix BIOS v3.19 Date: 2006.12.08 for P5LP-LE Leucite G8LE (EX331AA-ABA m7570n) motherboard?

I am running Windows 7 and I cannot find a compatible version.

One thing is for sure, BIOSAgentPlus says that my BIOS has a newer version available. The only information I need is the numbers as I do not have the subscription there to get more info. Can you please, help me?
