maxmem=4096 not working

[georgegeorge]

After I installed Snow Leopard 10.6.3, bootloader keeps restarting my computer after I click the hard drive with the Apple icon where the OS is installed.

 

Could my 12 GB of RAM be the issue? I hear Snow Leopard will restart if there are more than 4 GB of RAM. Do I put the command line within the boot.plist file from notepad to load only 4 gigs?

 

This is my com.apple.Boot.plist file:

 

<?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>i386 -v maxmem=4096</string>

<string>rd=disk0s2</string>

<key>Graphics Mode</key>

<string>1280x1024x32</string>

<key>Boot Graphics</key>

<string>Yes</string>

<key>Quiet Boot</key>

<string>No</string>

<key>Timeout</key>

<string>5</string>

</dict>

</plist>

 

Even though the screen resolution does change with "1280x1024x32", when I add maxmem=4096, the bootloader still shows "12279MB memory". Why is that?

 

BTW, is the boot flag supposed to be cpu=1 or cpus=1?
