I have made a Install disk on a usb hard drive by cloning the Leopard-AMD-10.5.1.iso and setting up the boot-loader. Installed the Mech-sse2 kernel and install my Ati drivers from 10.4.8 Jas.

The boot-loader runs fine. I have used (-legacy -v cpus=1) plus tired all others. The kennel loads and does not panic and start to load the installer. The problem is that the boot hangs after the boot disk has mounted. (Got boot drive Bsd diskxrx ....)

I have tried Unpluging all other drives and changed bios settings and i dont think its a jumper setting because the jas 10.4 installer loads ok off the disk. I can load into single user with (-s) but after that it just hangs (i left the computer on half a night just to see if it could pass that bit).

In the verbose output i dont understand 1 or 2 things like "com.apple.driver.appleacipplatform has limited dependencies on both com.apple.kennel and com.apple.kpi use only one style"
and "Local Apic version not 0x14 as expected".

Thanks for reading and sorry for being a noob
