Kernel Panic - 2007/09/30 07:20I have a Powerbook G3 266, with a PRAM battery that needs to be replaced so I have to keep the computer charged in someway at all times. If I don't I get the floppy disk with a question mark flashing and its time to load the OS again from the disk drive and install again.
That said, I am running OS 10.1 and have 192megs of ram
The hard drive is 18gig
I got the following "panic" a couple of days ago and when I loaded the OS over it by starting from the CD and pressing the C key the panic went....

Debugger (panic)
Waiting for remote debugger connection.
Is there anyway I can avoid this panic appearing again ? Can I run 10.2 on this machine ? If so, how ? I am running OS 10.1 because this allows me to access a Belkin USB Card that I have installed in the PCMCIA card slot. Can I run such a card under say 9.2.2 ?
The panic occurred when I was coying files from iTunes to my MP3 player that was connected to the Belkin USB Card in the PCMCIA slot. Is this a factor ?
Your help in this matter would be very much appreciated.

Re:Kernel Panic - 2007/10/09 01:44I must have missed your post but in case you still need answers.
Yes, you can run up to OS 10.2.8 and later using XPostfacto freeware on your Powerbook.
OS 9 has USB capability but there is a chance it may not work. Check Belkin's site for compatibility and Google the card model and OS 9 to see of anyone has had problems with the combination.
I would avoid using OS 10.1 and would definitely suggest going with OS 10.2 for the Powerbook. There is much more hardware and software support for OS 10.2 than OS 10.1 and it is a better OS.
You should add more RAM but it will get by with 192MB but will do much better with 256MB or more. I suggest 320MB or more.

Re:Kernel Panic - 2007/10/17 01:39The most common cause of panics is faulty memory. Then again, OS 10.1 Puma wasn't that stellar when it came to stability.
If possible, get memory that is both tested and certified to run on the Wall Street series 'Books. The correct memory for these models has 8 memory chips on each side rather than 4; and it's slightly shorter than a normal SO-DIMM. Maximum capacity is 256 MB per module, for a total of 512 MB.
Jaguar wouldn't hurt, either. With it, you can upgrade to iTunes 6, which is still available for legacy computers via Apple Support Downloads
If you must use Puma, check your base version. Version 10.1.0 will need Security Update 7/18/02 for 10.1 installed first to receive other patches through Software Update. Later versions need the same, but the update takes a different form.
Certain of the Wall Street 'Books used G3 CPU's without L2 cache. I seem to remember reading about a utility that could check for this flaw; and that the flaw may have contributed to some really odd issues.
