I have installed OSX 10.6 to my machine (HP ProBook 4420s), with iBoot. But after the installation process, the machine will complain about a hibernate image being too old and restarting, never being able to login.
Also, wifi and usb ports won't work. And the display has only one ress and its the wrong one.
I've tried to do a combo update to 10.6.8, and use MultiBeast to fix this, but it doesn't. It either panics, or doesn't solve the problems.

Any ideas for this specific model?
