Dear List
find attached a patch to get the WMI buttons going for the Tabletkiosk
eo7300
of course i will host this driver on our website but if they ever get
included , i would be more then proud.
As i am not a frequent patch sender, feel free to bitch me about
condingstyle or anything else to get this patch fly.
Cheers Rob
