BIOS conflict in Toshiba laptop

    Hello, group,

    Please forgive me if this question has already been posed and answered.
    I've Googled it and seen references to it but no solutions. I have a
    Toshiba M45 given to me by a friend to fix if possible. So far I haven't
    been able to help. When the laptop starts it goes into the BIOS but gives
    an error message that there is a conflict with the PCI serial bus controller
    in Slot 2. It offers F1 to continue or F2 for setup. F1 reboots the
    laptop, F2 gives no hardware options except to disable wireless, usb and
    touchpad. I've tried disabling all of those. Also I've removed the
    wireless card, the modem, the cdrw to no effect. I also tried known good
    memory sticks - no difference. In its present condition it therefore just
    boots to BIOS but goes no further. One thread mentioned that the CMOS
    battery might be bad and to replace it. This is not so easy on this model.
    It's on the bottom of the motherboard and is soldered into place. What was
    Toshiba thinking? Anyway, I'd like to hear further suggestions from those
    more experienced than I am. Thanks...J

    I had a dell that wouldn't boot. Previous owner had let the cmos battery
    go flat.
    It's rechargeable, and had correct voltage, but couldn't find any way to
    reset the cmos controller chip. Reset pin didn't help.
    Removing and replacing the same CMOS battery fixed it.

    Yes, have tried that. No go. F1 reboots the laptop. F2 allows you into
    the BIOS but there's little you can do to change hardware. Thanks for the
    thought, tho. J

    I'm thinking that this might be worth the effort. Unfortunately on this
    model the battery is soldered onto the bottom of the motherboard. I guess I
    should go ahead and try de-soldering it and finding a replacement. After
    all, what's the worst that can happen? Already I can't boot into an OS.
    Thanks...J

    As you know, the Toshiba BIOS has very few options. Although all is not
    lost. As they have a BIOS utility that runs under Windows to make more
    changes. Unfortunately in your case, this isn't an option. Although
    there was a DOS utility to make BIOS changes too. I don't know if this
    still exists, but it might be worth checking out.

    Thanks for the suggestion. I can't get past the F1 and F2 options screen.
    There's no chance of booting a cd or floppy. I was hoping against hope that
    there might be some magical keystrokes or something to get past the BIOS.
    No such luck. Next stop is de-soldering the cmos battery in hopes of the
    BIOS forgetting its present problems. If that doesn't do it I'll punt on
    this motherboard and part the machine out. Thanks to all who've tried to
    help. J

    I would reflash the bios if you can. I'm suspcious that someone did
    this previously .... with the wrong bios.

    That's an interesting option.
    Some of the Toshiba's had the ability to flash a bios on a laptop
    that wouldn't boot. Something about shorting some pins on the parallel
    port to get it to boot from a floppy.
