Can't even boot to installer

[shawiz]

Hi everyone!
I just downloaded 10.5.2 Rev.1 and try to install it on my machine.

Althon64 X2 4200
NForce4 SLI
GForce 660GT
2G DDR400 RAM
80G IDE hard drive for my leopard
other two SATA and one IDE hard drives

It turned out to have a panic at the first time it boots up
The screen is almost the same as the picture in this post
http://osx.kbot.de/comments.php?DiscussionID=529&page=1

except that on the first line it says "panic... kernel trap"
and the backtrace was terminated by a "invalid frame pointer 0"
so I don't know what caused the problem.

I followed some of the advices such as use -x , -s, ...
or replace the AppleNForceATA.kext with another one
none of them works

Anyone had this situation before? what can I do?
Thanks in advance
