OS X boot keeps crashing

[agusta]

Guys, need your help. I have successfully installed iAtkos v7. My notebook specs:

System Model: HP Pavilion dv6700
BIOS: Phoenix BIOS 4.0 Release 6.1
CPU: AMD Athlon 64 X2 Dual-Core TK-57 1.9GHz
Memory: 2046MB RAM
Video: Nvidia GeForce 8400M GS

The installation went really smooth. However, after the bootloader (where I select which OS to boot i.e. Windows, OS X) after I select to boot Leopard I only get up to the apple loading background and right after that my laptop reboots. I have reinstalled Leopard twice and same thing happens. If I view the Leopard boot with a -v option the very last line I see is "Starting Darwin X86".

Could someone please help me out. Thanks in advance.
