Grrr...  I bet this board has a Windows XP sticker on it? ;-)

\_OS does not do anything for modern BIOSes such as yours, i.e., it is 
only useful for up to MS Win2K-ish BIOS, only because MS mandated it 
from XP AFAIK.  By default, \_OSI is used and it will match "Windows 
2001.1" just fine.  Although the DSDT has listed many other 
non-Windows OSes in the table, they are just place holders AFAICT.
