    Ok, that did not help at all. I did what was to be done with the intel based mac and the NVRAM did NOT reset at all.
    The PRAM is for G4 based macs and the NVRAM is for intel based macs and using the NVRAM doesn't require holding keys down before grey screen comes up and so doesn't the open firmware method as that is also for PRAM OR non-intel based mac systems.
    I have tried removing power cable, wait for 15 seconds then pluging devices and power back in, waiting 5 more seconds, then turning the mac on and nothing happens.

    I also try holding the keys on the keyboard but the same thing happens. i am unable to reset the NVRAM on my intel based imac system.

    I also try and hold power button down during the whole boot process. isnt there any 3rd party software i can use to reset it

    hello, again, do NOT post THAT website link again.
    I know the differance between nvram and pram.
    I dont wish to follow those steps again as they are not usfull.

    I NEED SOME OTHER APP to reset for me if that is possable.

    Also is there an alternative for BOOTCAMP for installing xp or dual booting with mac?

    In post #1 you asked for help resetting the NVRAM. I linked Apple's procedure on how to do it.

    Just because the procedure did not work to solve your problem...it was not necessary to make the comments you made above (that I quoted).

    If you want help around here...being friendly will get you more help!

    Then, you're not doing it correctly or there is a problem with your iMac. The procedure Nick linked you to is the correct one for resetting the NVRAM on your iMac. Removing the power as you already tried is for resetting the SMC.

    Why do you think you need to reset the NVRAM for setting up Boot Camp? Also, you might adjust your attitude a bit if you really want help from our forums....

    But, i have tried those procedures provided by apple and they DONT WORK. So, on intel macs please let me verify with you all, hat nvram and SMC is the same thing? Which holds the system time, boot disk, etc
    I have read that guide or link to resetting non volaitil memory in apples website

    No, NVRAM and SMC reset are NOT the same thing.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.

    No they are not the same thing. If you go to the Apple Knowledge Base and look up NVRAM and what it does, and then compare it to the System Management Controller (SMC) and what it does, you'll see the difference.

    Also, you never answered our question as to why you think you need to reset the NVRAM before using Boot Camp?

    From Apple:

    Your Mac stores certain settings in a special memory area even if it is turned off. On Intel-based Macs, this is stored in memory known as NVRAM; on PowerPC-based Macs, this is stored in memory known as PRAM.

    Information stored in NVRAM / PRAM includes:

    Speaker volume
    Screen resolution
    Startup disk selection
    Recent kernel panic information, if any


    Now look at Apple's explanation of SMC:

    After performing normal troubleshooting, these symptoms may indicate that an SMC reset may be necessary:

    Fans
    The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.

    Lights
    The keyboard backlight appears to behave incorrectly (on Mac computers that have this feature).
    The Status Indicator Light (SIL) appears to behave incorrectly (on Mac computers that have an SIL).
    Battery indicator lights, if present, appear to behave incorrectly (on portables that use non-removable batteries).
    The display backlight doesn't respond correctly to ambient light changes on Mac computers that have this feature.

    Power
    The computer doesn't respond to the power button when pressed.
    A portable Mac doesn't appear to respond properly when you close or open the lid.
    The computer sleeps or shuts down unexpectedly.
    The battery does not appear to be charging properly.
    The MagSafe power adaptor LED doesn't appear to indicate the correct activity.

    System Performance
    The computer is running unusually slowly although it is not experiencing abnormally high CPU utilization.
    Application icons may "bounce" in the Dock for an extended amount of time when launched.
    Applications may not function correctly or may stop responding after being opened.

    Video
    A computer that supports target display mode does not switch into or out of target display mode as expected.
    A computer that supports target display mode switches into or out of target display mode at unexpected times.

    so SMC hold the power, system performance, video and fans settings and the NVRAM holds the startup disks, speaker volume , screen resolution and the recent kernal panic information?

    Thanks in advance.

    i dont need to reset SMC i need to reset the NVRAM instead of SMC. Because the NVRAM holds the startup disk and bootcamp wants be to update the rom info right?
    So it must be the NVRAM. Since i have done that i just cant get it TO WORK!!!
