    So the title says a lot. Here is the background of my question:

    I have a macbook. I was running v 10.4 until recently. Now i'm running Ubuntu version 8.04.
    I'm trying to enter the mac equivalent of BIOS in order to disable my trackpad/mouse (its broken and causing some problems while trying to use an external mouse). I know that the Mac equivalent of BIOS is "open firmware", and that to access it, you press command-opt-o-f while booting. However, I've tried this and it still seems to boot normally. I'm wondering if there's a different set of keys I need to press in order to access open firmware now that I'm running a linux Operating System.
    Can anyone suggest how to do this?
    Any help is much appreciated.
    Thank you!!

    Intel Mac's use EFI, and you can't access open firmware as you did on PPC macs using 'cmd-opt-o-f'. There is 'rEFIt' (http://refit.sourceforge.net/), that allows you to interact with EFI.

    I don't think you can disable the trackpad in the EFI.
    The trackpad is internally connected to an usb-port, together with the keyboard (at least this is so in a MBP). So disabling this port will also shutdown your keyboard.
    You could try to unload the driver for the trackpad in Linux.
    Maybe a google search for: "ubuntu disable trackpad" can fix your problem.
