    Force A1181 Mobo to Boot on External Monitor

    I have a Macbook A1181 (820-2279-A motherboard), which is probably this model: _everymac.com/systems/apple/macbook/specs/macbook-core-2-duo-2.1-white-13-early-2008-penryn-specs.html

    It is essentially just the laptop bottom (no LCD).

    How can I force this to boot to an external monitor?

    I would appreciate people with personal experience doing this. Seems an almost unexplored pursuit.

    I wish I was a competent electrical engineer.

    I learned a bit about reed sensors/switches vs. hall-effect.

    I'm not sure if my magnets are powerful enough. They are not terribly strong.

    I don't even know if the hall-effect sensor tripping will force it to (from boot time) display only on the external monitor. Anyone confident in messing with this circuitry?

    On page 3, you can see the pole configuration. I have the LH package (I am pretty sure). Any thoughts? Honestly, the chip only says:
    Code:
    13E
    This style hall-effect sensor seems to have a universal configuration? The configuration was the same with the 3 manufacturers I checked.


    This kid "sort of" did what I am trying to do:

    *What he is calling a reed switch is a hall-effect sensor; more info (for amateurs like me):
    _www.meder.com/fileadmin/meder/pdf/en/Reed_Sensors_vs._Hall_Effect_Sensors.pdf

    Sorry to ask such beginner-esque questions. I am slowly learning.

    Thanks,
    Jaime

          That link only refers to (normal, complete) laptops. I only have a bottom (just mobo, essentially).

              spidey,
              Bios-mods has nothing. Please do not post in my thread anymore. You ever seen a Macbook with a BIOS?

                how rude!
                Just cook it! It's already broken.

                    you are an interesting person. yes of course mac has a bios, but you cant enter any setup or bios utils similar to pc's. i am an electronics/computer hardware tech. and doin this job 15+ years. it was just an idea for you to figure it out, and modding bios is not my intelligence so tried to direct you to a better place. But never mind, doesnt worth. find you own way.

                      PPC Macs used Open Firmware whereas Intel Macs use a technology called Extensible Firmware Interface or EFI. They do not have a normal BIOS. I have played with Open Firmware before (making USB drives enumerated & bootable). It required being able to see it, though. If that [BIOS diddling] were even possible, how could I even do that with NO DISPLAY?

                      it was just an idea for you to figure it out
                      The reason I created this thread was because I could not figure it out. You're an experienced tech, and these are your replies/posts?
