aaar Level 1 Level 1
Hello guys,
i have a macbook pro, that i formated with a windows 7 dvd, now i ONLY have a windows 7 on my macbook pro.(I wanted a clean install with os x before i puted windows 7, but i coudnt because each time i tried to boot from os x dvd i got a kernel panic, thats why i formated the entire hard driver and puted windows 7)
But now i realy want the mac os x, i really tried evrything, evry dvd, evry key combination nothing worked.the error i get is: yo need to restart your computer ....
I alo cant acces the hardware test....
nobody could help me on the forums...

Today i tried to boot from a linux bootcd,then i got the next error:
mp-bios bug:8254 timer not connected to IO-APIC
kernel panic: not syncing: IO-APIC +timer doesnt work.

As you can see the problem is apic,when i press noapic the linux starts up, so i think if I could disable the apic before starting to boot from the os x dvd should help...
on windows computers yo can disable the apic in bios, does anybody have an idea how i can do it on a macbook pro?
or maybe other ideas that can repair the bug?

macbook pro, Mac OS X (10.5)

    I am looking for this for a month, i have searched evrywere but nobody couldnt answer, i know what a kernel panic is but i have to find a way to fix it ....

    I cant find any solution on forums...

    Is here nobody that knows how i have to turn of the apic? so i can boot from mac os x dvd?
    or a special key combination, that boots from the dvd while the apic is turned of?

    It's not a bug, it's because peecees don't read Mac without 3rd party programs.
    Apic supplies IRQs for intel use in a peecee system.

    I know you've said that you tried all key combinations with your Mac install DVD.
    Is this DVD the original disk that came with this machine?
    Have you tried holding down just the "option" key while booting?

    Oh yea, the reason not many people have responded is because very few, if none, have
    formated a Mac computer to use with windows only..

    very few, if none, have formated a Mac computer to use with windows only...


    Except people do, reviewers have put Vista on MacBook Air as sole OS, same with Windows 7. Anyone running Windows on a dedicated hard drive in a Mac Pro could be said to also. There is no need for OS X in such cases.

    And has nothing to do with the question at hand. Folks that call "peecee" also tend to have their own agendas.

    I have a hard time understanding the OP.

    i can get a mac os x snow leopard on a windows PC, but i can't get a mac os x on a macbook pro... ***?

    am never gonna buy another mac again( except an iphone :p)
  • aaar Level 1 Level 1
    OH i have an idea maybe it will work, if you guys help me...
    I can't boot from mac os x dvd, but before formatting i could start mac os x that was installed on the hdd.

    IF I copy an installed version on a differed hard drive and i copy it(with a linux bootcd or something) to my own hard drive, than it should work or not?

    Now my question to you is: is there any image file that is the mac os x snow leopard, and that i just have to mount to an hard drive to boot( i can mont it using macdrive)?

    maybe i can fix my problem from the mac os...

    "+Very few if none+" was referring to the folks in the discussion area, not the whole wide world.

    I've called window machines "dosboxes" and "peecees" since 1984.
    Sorry to force my agenda on anyone.

    I also have a hard time understanding the OP.

    This was said on the other thread, but you seemed to have ignored it.

    You said you got the kernel panic when it was originally loaded with Mac OS X. If so, you most likely have a hardware problem. Instead of getting it fixed, you installed Windows 7. Now, you want to install Mac OS X, but the hardware problem is still there.

    It really sounds like some component that Mac OS X uses, but windows does not, is not functioning properly. If that is the case, none of us here can tell you what to do to make it work. If the machine does not boot with the original gray disk that came with it, something is broken. It is probably not software. It is probably hardware. You'll need to have it repaired.

    Hi Barney,
    it seems that the Mac OS isn't idiot-proof, after all...
    It seems this 'expert' in PC world screwed-up his laptop & blames everybody & everything else for it.
    After reading his both posts I have to but laugh...

    You are working ages on a mac os and dont know how to fix a problem like this...


    It's far from a common problem. I've never seen anyone post an IO-APIC issue before. Doing a search for your exact error message turns up all kinds of links for people trying to install Linux, Ubuntu, or some other non Windows OS on their PC. This thread is the only one I found related to a Mac.

    Just a note on this:

    i can get a mac os x snow leopard on a windows PC


    You do realize that's illegal, right? The user license clearly states that the Mac OS is to be installed on Mac hardware only. Not to mention that even if you do somehow manage to get OS X installed on PC hardware, it's almost a 100% certainty it will run badly.

    and tried to press option, c,d while booting(the dvd os x was in there)


    Just pressing? Try again, insert the OS X install disk and restart. When you hear the startup chime, immediately press and hold the C key until it is clear you've started up to the DVD. If this doesn't work, then that kind of brings this up:

    oh one more thing: i was also getting the kernel panic before formatting the previous mac os x


    Kernel panics are usually hardware related. What do you have plugged into the laptop? If anything, unplug them before attempting to boot to the OS X install disk. If there's nothing plugged into any of the USB, Ethernet or FireWire ports, the it's most likely bad RAM. You'll have to bring the Mac in for service to get that checked out under warranty.

    apple on pc: it was just to see if it was working, and it worked 100% right, and i didt knew it was illegal...

    nothing was plugged in, and the warranty is over....
