Force resolution not working?

[ObsoleteYeti]

Hey guys,

 

I'm new to all this Hackintosh business so bare with me.

 

I'm using an HD 4850 (which I cannot find drivers/kexts for) and have tried to force a resolution on boot by editing the 'com.apple.Boot.plist' file.

 

I changed it from:

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">'>http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>Kernel</key>

<string>mach_kernel</string>

<key>Kernel Flags</key>

<string></string>

<key>Boot Graphics</key>

<string>Yes</string>

<key>Quiet Boot</key>

<string>Yes</string>

<key>Timeout</key>

<string>0</string>

</dict>

</plist>

 

To:

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>Kernel</key>

<string>mach_kernel</string>

<key>Kernel Flags</key>

<string>"Graphics Mode"="1680x1050x32"</string>

<key>Boot Graphics</key>

<string>Yes</string>

<key>Quiet Boot</key>

<string>Yes</string>

<key>Timeout</key>

<string>0</string>

</dict>

</plist>

 

It is forcing a resolution, just not the one I have entered - it's forcing 1400x1050 instead of 1680x1050.

 

Does anyone have any ideas why?

 

Thanks in advance,

ObsoleteYeti.

why don't you try

 

<key>Graphics Mode</key>

<string>1680x1050x32</string>

 

?

 

i think this is the right method...

 

just give a try

Forced resolution works only for boot screen. It does nothing then system is booted and working. And as in previous reply it should be

<key>Graphics Mode</key>
<string>1680x1050x32</string>

not

"Graphics Mode"="1680x1050x32"

Tried the way you suggested and it still boots into 1400x1050.

 

Any ideas?
