I just do not understand how to do this. I have read everywhere and it must be too simple because no one really explains it. Most people tell you how to replace a kernel on a completed os installation. I am using the usb drive method and still installing snow leopard.

If the PC has a Pentium D... I am going to need the patched mach_kernel. How do I put the patched kernel onto the USB drive?

Thanks for any help!
