BIOS Update for Packard Bell IMEDIA 5165

Hi every buddy,
I just went to the update site for my computer.
A Packard Bell IMEDIA 5165
And there is an important BIOS Update...
The problem is, there are 2 versions one called 2.0U and the 2.0T... The only difference apparent to me is the publication date... 2.0T is older (28-10-2005) than 2.0U (08-02-2006)
Which one do I have to install?
I really don't wanna mess up with this installation... I could really use some advice on this...
Thanks

I checked the PB site. If u have a sunshine MOBO it is made by Gigabyte.
If it is sunshine then u should use BIOS revision 2.ou. PB said always use the latest version of the bios update. The 2.0u is for WinXP..
