No ToHkernel on 10.5.1, no sleepkernel on 10.5.2

[wassupdoc]

So I don't understand what I am doing differently.

I have downloaded both 10.5.1 and 10.5.2 dvds, burned the iso's without a hitch.

When I go to install the dvd loads up and I get the command line to enter startup arguments.

On 10.5.1 I tried without any argument which of course caused a reboot (does show installing mach_kernel though) as my prior posts stated, but when I enter "tohkernel" (don't worry I entered without quotes ) all it does is go back to enter f8 to enter options yada yada line

 

10.5.2 I have tried entering sleepkernel on the command line and it does the same error. When I try to run speedstep kernel or some of the other kernels they seem to start to load, but then I get a reboot anyway.

 

I think if I can figure out how to get tohkernel to load properly that may help me get leapord installed. About to give up and try tiger.

Thanks
