[germany99]

Sup everyone.. first of all sorry my inglish..

Second i am trying to install this Mac 1.4.8 JAS.. i tried to install rebooting.. all went ok but when i'm going to use disk utility to use partition it just not appear there.. it only appears my dvd-room

 

I made the partition with windows: start > cmd > diskpart

i made a partition primary id=af..

 

i could make it work using vmware workstation 6 so i suppose it's a partition problem
