I'm using Leopard-10.5.2-AMD-EFI-Rev2
It boots but now I'm a screen that is gray with a darker gray apple logo.
I've been on this screen forever like 30 minutes.

I've already had problems with EBIOS read error: Device Timeout
I reburned the iso at a slower speed and now I'm on that apple logo screen.

try booting with -v -f switches at the bootloader screen. You will atleast see your problems if not boot completely

How do I do that?

when the machine boots for a few seconds you should see a black screen with white text on counting down. Just hit enter once then you can type in -v -f then hit enter

No screen like that on my computer.
I haven't installed it yet.
I'm trying to install it.

try pressing f8 as soon as dvd starts to boot you should get the options then

Thanks for the reply.
Trying it right now!
Thanks Again For Your Support.
Been Trying this for 2 days now.

k hope you have success

It was looking like it was working.
But then it kept repeating this error.

I've searched and it says to reburn the media? Is that right?

I've burnt 20 copies so far.

10 DVD+RW - 5 different programs
5 DVD-R - 5 different programs
5 NEW DVD+R DL - 5 different programs

So I'm not positive about this reburn solution.

Yes I've tried all different speeds to mostly slow ones.
