First, I want to say "Thank You" Andy. My AMD Phenom II 550 BE with 8GB of ram is finally able to run Snow Leopard the way it was meant to - Perfectly.
I can launch every default app that comes with SL with very little problems. For anyone interested in how I did it, here are the basic steps I followed:
I installed Snow Leopard using the "SnowLeoDVD". I then upgraded to 10.6.4 using the combo update and legacy_kernel-10.4.0 from "kexts.com".
I had to boot the system at that time using the following kernel flags:
busratio=20 maxmem=4096 arch=i386
I DID NOT use Marvin's AMD utility.
I applied a dsdt.aml to my Snow Leopard Volumes root directory.
I download and installed AnV's latest kernel - "AnV_Qoopz_xnu_10.4.0_Rel4" and the AMD_sysenter_10.6.4_patcher. From there, I installed the kernel as "Anv" and I applied the patcher files. From there I rebooted the system with the following flags: Anv (for the new kernel) busratio=20 patcher_opts=2 arch=i386 -force64 maxmem=8188 (for the full amount of my ram) and... THE SYSTEM BOOTED!
Strangely enough, my Processor was automatically recognized as an "Intel Core Duo". I had the full 8GB or ram that I've always wanted. And I could finally install Adobe After Effects CS5!!
Thanks again Andy for showing us AMD users some love.
