KALYWAY 10.5.1 reboot after kexts loaded

[kas]

Hi, i have got a MSI 6577 ( yeah, i know it is very old ), and i wanted to install KALYWAY 10.5.1, and after the kexts are loaded, it simply reboots the pc... Tiger worked perfectly out of the box with this mobo, but leopard won't even boot the install process... , is there anything i can do to access to the install, or there is no hope and i have to buy a new mobo?

 

My hardware is :

 

MSI 6577 ( HP pavillion 724.fr )

intel p4 2.4 sse2 only ( 845g )

768mo ram
