    Your post is confusing. Are you saying there's a solution to the GMA950 problems with desktops or notebooks that only has one resolution option (1024x768) after you've done an EFI + 10.5.1 update?

    I've done that update and I only have 1 option for screen resolution and that's 1024x768 in a Dell Desktop. This solution is a fix for that? If so, how do you implement it?

    I found this on the web - don't remember actually where, so I'll copy and paste it. It works for me with 10.5.1.

    ____________________________________

    Messing with the boot options
    Tired of typing '-x "Graphics Mode"="1280x1024x32@85" platform=ACPI or platform=X86PC' every time you boot? This is for you!
    NOTE: It is best to test out your commands before editing the Boot file. By testing, we mean typing your command during boot (Darwin). If it works, then proceed. Why? Because your changes to the boot file is used EVERY time you boot into Mac OS. Typing out the commands during the boot only affects the OS during that current boot. Rebooting clears it.
    Browse to
    /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
    and open it up in your text editor- You can add some switches in here to make your life a little bit sweeter...
    HINT: If you are having difficulty saving changes to com.apple.Boot.plist; Open Terminal and type

    sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

    just copy and paste the text) and press enter. Use the arrow keys to move the cursor. Ctrl+O to save (and then press Enter to save) and Ctrl+X to close.
    TIP: If you've installed the Developer Tools (free for download with an Apple Developer Connection membership, or on a Mac OS X DVD), you'll get the program Property List Editor, which will make editing .plist files a tad easier. To run it as root, type in sudo open /Developer/Applications/Utilities/Property\ List\ Editor.app path-to-a-plist-file, or sudo open path-to-a-plist-file if .plist files are already associated with Property List Editor. As of version 2.1, this is a Universal application.

    To automatically use a certain graphics mode
    <key>Graphics Mode</key>
    <string>1280x1024x32@85</string>
    Note: If your video card is using VESA 2.0 drivers, leave out the '@85' part as it only works on VESA 3.0 will cause the system to reset before getting anywhere.
    If you need to specify a platform
    <key>Kernel Flags</key>
    <string>platform=X86PC</string> or <string>platform=ACPI</string>
    If you experience stutter like (shutter) syndrome; usualy on dual core processors
    <key>Kernel Flags</key>
    <string>idlehalt=0</string> or disable one core <string>cpus=1</string>
    If you don't want to see the Darwin text on boot - HINT: You can get the prompt back by holding "ctrl" at boot.
    <key>Quiet Boot</key>
    <string>Yes</string>
    If you want to show the Logo with spinning Boot Graphics
    <key>Boot Graphics</key>
    <string>Yes</string>
    To put in switches (-v, -x, -s, etc)
    <key>Kernel Flags</key>
    <string></string>
    Speed up Darwin's timeout count-down
    <key>Timeout</key>
    <string>8</string>
    Replace 8 (default seconds) to a new value.
    To set Darwin to boot from a particular partition:
    <key>Kernel Flags</key>
    <string>rd=diskXsY</string>
    Where X is your hard drive number and Y is the partition number (BSD naming scheme)
    if you are unsure about the rd value open Aplications>Utilities>Disk Utiliy, click on the partition with OSX installed and click on info, the right "rd" value is the value from "Disk Identifier"

    EDIT: I've tested this a few times, doesn't seem to want to work for me. Anyone got any ideas? T
    This page has some info: http://neonkoala.co.uk/content/view/33/34
    work fine for me, I use <string>rd=disk1s3</string> to boot from the 3rd primary partition of my second disk.
    NOTE: The kernel flags option has made some computers unbootable. </br> Type "-F mach_kernel -v" at the boot prompt if your computer fails to boot after messing around with this.
    NOTE 2: **ONLY IF YOU HAVE PARTITIONMAGIC** In the event you are not provided with a boot prompt, just boot to Windows normally. In command prompt, use diskpart to set the second partition active. This will boot the computer directly to OS X 86. Once booted, delete the changes made to the com.apple.Boot.plist file, save, and reboot. Use PartitionMagic( There may be another way?) to boot the computer, then reset the Windows partition back to active. Reboot again and you're back to your OS Selection menu.

    Here is an example /Library/Preferences/SystemConfiguration/com.apple.Boot.plist:

    <?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>-legacy</string>
    <key>Boot Graphics</key>
    <string>Yes</string>
    <key>Timeout</key>
    <string>10</string>
    <key>Graphics Mode</key>
    <string>1280102432</string>
    </dict>
    </plist>
