You can take a look with Everest at the SLIC entry. The oem id & oem table id must be _ASUS_ & Notebook.
and this means that whichever version of vista i install it will activate? dont i have to use a certain key for the Asus OEM installation?
Yes a slp2.0 key is needed and the asus certificate then you're good to go. Keys are floating on the internet, google can be of some help.
