    Ok, hope this isn't frowned upon.
    Basically I was wondering how I would go about identifying and locating the BIOS chip on the core duo model.
    Thats all I am going to say! ;)

    It is frowned upon.

    Say no more. I think I know what you mean, mate. Have you tried the CMOS battery before you start fiddling with bios? Its usually a little yellow bugger.
    Cheers

    Yep!
    Panasonic wised up on this model!
    However if we say for arguments sake I goosed the BIOS during a reflash then I should be alright!
    There is a list of potential suspects in the Service manual. I guess it might be in the list of IC's. There is one called Security chip.
    Just need to do some homework to ensure I can source the correct replacement. If so, then game on!

    Of course, for arguments sake. While I'm no expert in the CF-51, removable BIOS chips were more or less discontinued around the turn of the millennium. They are incredibly rare. So if you are going to do something with it, which i'm not saying you will, just pointing out a hypothetical scenario, there is a big chance it wont work. And I doubt you're interested in *cough* soldering *cough.* But I must warn you, whenever you start fiddling with bios, it can go to hell in a hand basket faster than you can say "I was just..."

    What I will say however, is that if you are incapable of editing the boot order for some "strange" reason. Perhaps you're a newbie and don't know how bios works. What do I know? Then you can use PLOP boot manager, which is a boot manager that installs on the hdd. You can then set the unit you want the TB to boot from via simple menu.

    I used it on my friends CF-29 that had some sort of strange bios "bug".

    Cheers, mate. And good luck.

    Without doubt I will not be doing any of the soldering myself! That will be farmed out to a professional. However it would help to get the right chip.
    Without wishing to be rude, the more vague, the more likely I am to find out what I need to know. If Panasonic used similiar MB's for the core duo across the models and the associated components are identifiable, then I might be in with a shout.
    Worst case is that the MB gets toasted and I use the best components to tidy up a tatty one!

    You really should forget about about what you are trying to do and just us it as a parts machine AND you are walking a very fine line here and as in the past it will end up " thread closed" :( been there..done that...felt like a you know what afterwards :frown:

    You're barking up the wrong tree.

    The bios chip been tried by members before and epic fail comes to mind.
    TPM Chip

    It's tied to the motherboard ID and swapping it won't work either.

    Someone in buy sell trade was looking for a video cable. That cable cost me $28.00 plus shipping. Quick way to recover some losses.
