hi all,
i now have two computers. [debian + xp]
i can start linux from windows by sending packets to mac address.
but this method not holds for windows :'(
i know this debian mailing list but writing this email just because of my curiosity ;) 
dont know where i am doing wrong ?
any ideas why the other computer doesnt start ?

Cheers,
MFA
