Powerbook G4 is not booting and gets this trap message (and another). Can anyone help me get started with how to trouble shoot this ?

I have typed the following message so far, if other information is needed please let me know.



unresolved kernel trap(cpu 0) 0x200 - Machine check DAR=0x12eb1000 PC=0x12e99e6c

Exception state (sv=0x12BBE200)
PC=0x12E99E6C; MSR=0x00149030; DAR=0x12EB1000; DSISR=0x4000000; LR=0x12E99F

perviously dumped as "Latest" state. skipping...

I do not know what the error means. What model PB do you have? Have you tried to run disk utility, via the install dvd/CD? Have you added any hardware lately (E.g, memory, etc)?
 
That's a kernel panic, and is caused by faulty hardware or faulty software (heh... what else could it be? ;) ).

Have you recently added any peripherals to your computer? Howabout added any RAM? RAM is particularly notorious for causing kernel panics...

From the panic itself, it looks like it crashed during some "AppleIO" procedure, which usually involves RAM or hard drive... what recently changes, if any, have you made to your system?
 
Powerbook G4, 512MB RAM, 15", OS X 10.2
Unless both RAM chips failed, they aren't the problem (removed one at a time and still got panic).

Airport card stopped being recognized by the computer, couldn't get a connection with it at all prior to this panic.

Also, some new software was installed - 2 games - fairies and atlantis and i question - just prior to the error too.

If these are the problem, either the hardware or software changes - what could be done from this point to correct it? Any way to manually uninstall software from single user mode for example? Is there a way to fix the OS without the CD or a way to download it and burn from a PC?

Thanks in advance for your assistance!
 
Any advice for how to get the airport card out. Looks like the piece of tape that is normally attached for just such a purpose is missing. tried to unscrew case but one stubborn screw just wont give.
