Alright guys!

- So basically, i figured out what the error was. It was my IDE Drive. Because every time the "Still waiting .." error came, my drive stopped running.

Now, i don't have any SATA DVD or USB DVD drive. So i took another IDE drive which i had, and tried that. An Optiarc drive.

And it worked. Only with iPC though!

So i wrote "-v -x -f rd=disk0s2" and BAM, it accessed the installation.
I formatted and partitioned my HDD to a GUID partition. Customized my installation, and installed. Now, at the boot up i wrote "cpus=1 rd=disk0s2 -v -x -f"
it got through some stuff, and started. BUT it only gave me a blue screen.
Now before this, it came all up with some graphic codes and display and so on ..
So i thought, "It's probably my ATI graphic card." So i went trough the install again, so i could install some ATI drivers, i wrote the "cpus=1 rd=disk0s2 -v -x -f" again, BUT!

It didn't redirect me to the installation! It got me to the brand new installed iPc 10.5.6!!

And it works right now! I'm so happy! thank you for helping me!

-UPDATE-

Alright guys some updates here:

I have to boot up with the CD every time. And with the command: "rd=disk0s2 -x"
Sound doesn't work. Tried the VoodooHDA.kext and all kinds of different shit.
Network works perfectly
The quartz thingy for the graphics is on "Not Supported." I have found the DeviceID & VendorID though, and found out that the 3650 series had the same ID's. Tried to install it, didn't make any changes. (I have the 3600 series.)
Printer works.
Uses all four cores.
USB doesn't work. - Even though i tried the USB Mass fix, and the USB Mount fix. Not together, since it would mess up if you did. I've done multiple installs, with different kernel extensions.

Hmm .. If anyone could help me with the sound, i would be very glad.
