Thank you very much for your respond. I did manage to bypass my last problem by going into Advance Setup-> and change the "Set custom kernel MMU region base address", and the "Set custom kernel region base address", since my MMU base address is "0x000" and DDR2 RAM base address is "0x06000000" (with virtual memory, this base address is 0xC6000000).

It started to move along until I get this bug/failure message:

Unhandled exception# 12 in kernel mode

Have you seem this before? Any help is greatly appreciated.
