Lots of Problems with EFI Rev and AMD

[RealRitzcracker]

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.
