gmax3100 not working

Recommended Posts

Hello everybody. I have a problem with my graphics card.

First i wanna say i ve already tried searching on google, on this forum ecc, but none tutorial,old topics worked with me. 

The problem is that i can use only 1024x758 resolution. But it is supposed to be much more. 

I ve tried setting 32bit, installing a lots of next ecc. but nothing.

Can someone help me? Thanks

Hi again,my friend

To run Lion on to 32 bit mode you need to write on Extra/com.apple.Boot.plist(etc:org.chameleon.Boot.plist)

 for 32 bit mode,write this one(red font)

    <key>Graphics Mode</key>
    <key>Kernel Flags</key>
    <key>Legacy Logo</key>
