So I went back to the dlach method in the first post (F3a bios, etc) and my machine is working great. Have video and audio all working. I would still like to get my 8gb of ram online too. So I'm considering buying a cheap video card instead of trying the aserebln method (given that I've lost HOURS on trying to get that to work).
Does anyone have a recommendation for an inexpensive plug and play video card?
good to see - I think it's most important, that you have a working installation.
If you do feel like playing arround, you can try out an installation as follows:
1. You need 2 USB memory sticks and my attached image file.
2. Download the image and place it on your Desktop.
3. Restore your Mac OS X Install DVD to the first USB stick, like described in serveral tutorials out there. (This is very usefull at all and speeds up boot and installation process.)
4. Prepare a ChameleonBoot Stick with the second one
4a. Plug in the stick and open DiskUtility.app
4b. Format it with one partition (fat) and be sure that under "Options" "Master Boot Record" is selected.
4c. Find out the device number of the stick (use Info button, it will show you e.g. disk2)
4d. Unmount the stick (not eject)
4e. Open Terminal.app and type
sudo dd if=Desktop/ChameleonBoot.dmg of=/dev/rdiskXX = Number of stick you've found out in 4c.
This will takes about one minute, be patient. After dd has quit, it will give you a result message and OSX will mount the dumped stick automaticly. (Shown as "ChameleonBoot" on your Desktop)
If you had success with these steps, you can try out, if your OS X Install DVD Stick (3.) will boot.
You can use all your RAM, it won't touch your workin installation.
But you have to flash your BIOS to F4 before and make the right settings.
5. Switch out your PC, plug in both sticks. During boot hit F12, select Hard Disk as boot device, in the appearing sub menue select the Chameleon USB stick (it will shown with the manufactor's ID)
6. Chameleon Boot Menue comes up and you can select Mac OS X Install DVD. Now it should brings you into the Installation Environment.
Now you can decide to make an installation on your second HDD, later you can boot this installation with the ChameleonBoot stick too. (via F12 button)
If it fails go back to your working installation and don't forget to flash the BIOS to F3 in this case.

Doosje has uploaded a patched Chameleon-RC5, so I've modified the image for the stick with this bootloader.
If you're booting your installation with the ChameleonBoot stick, just create a new one with the attached image and speedstep should work.
