Can't install mac os x on macbook pro because of kernel panic: IO-APIC

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)

Then as has been mentioned, it's looking like a hardware issue. Could be RAM, a faulty system board, etc. You'll have to bring it in to an Apple service center to have them figure out what's wrong with it.

Just another thought. Have you added extra RAM to your MacBook Pro? The newer Macs need to use matched RAM. At least the Mac Pros do. You can't just match up the same specs such as speed, latency, etc. If you put in more RAM, you must remove the existing RAM and put in sticks from the same manufacturer that is designed to work with your system.

So if you added extra RAM from another vendor, take that out so the MacBook Pro is running only on the RAM as it came from Apple and see if that helps.

Hello aaar

I have the exact same problem, with the difference, that I do not want to install Windows but to boot my OS X install. After a nightly freeze of my MacBook the system didn't come up any more. Not from the hdd and not from the original install DVD! After days of trial and error I succeeded booting Linux with the noapic kernel boot flag.

So guys, how could someone pass the noapic XNU kernel flag on boot? I have an obvious hardware bug with the APIC controller, but my MacBook still works fine under Linux.

aaar, what did the Apple Store say??

Greets,
Erik
