garbage screen of death

nosey

This has happened three times now, but this time I have a photo. Booting from the Jaguar boot CD and examining the disk reveals no problems. Reinstalling the system on the same cd will produce the same thing. And, even though I have a perfectly good system on another partition, the Apple boot cd for jaguar insists on making me install the system again because you cannot select a system to boot from from preferences on the cd.



Damned annoying, it is. Just a poipnt. There was no haxies or other third party software on the system. Nor did I have any OS9 software installed. Anyone else have this screen?

ask Mulattabianca, she has had this problem too.

Is your firmware up to date?

nosey

While trying (unsuccessfully) to find the firmware version using profiler, I cam across a log of events. Does this mean anything to anyone, or is it just more bad news?

Those are logs of the kernel panics you have had since you installed 10.2. A kernel panic is a software failure at the lowest level that almost always locks up the machine, requiring a reboot. You might find these Apple KBase articles to be of some use:

do you have SCSI devices ?

nosey

Nope... no scsi devices. I haven't used those since my Amiga. Too haphazard to hook up.



I also the advice of some crawlingparanoia and tried to update the firmware. It said it copuldn't be updated with his version of software (Jaguar) The firmware thingie was also a classic program, which meant trying to find OS 9, installing it and restarting... yadda yadda yadda...



It's just so frustrating... and I just know that there are going to be some serious ramifications with newbies getting new machines, with gobs of hard drive space, and a serious problem like this cropping up to ruin their day. I only lose 14-20G of stuff, most of which is recorded on CD's if the absolute worst happens. With one of the new machines, it can be up to 40 or 80, or more.



I shudder to think of what would happen.



To think most of the hassle of fixing something like this could have been offset if only I was able to set a startup device from the boot cd's, instead of having to install a new system somewhere else.

defiant

just install OS9 and install the firmware update. if you're to lazy to do the things we tell you to try, why even bother to ask ?

nosey

I did install OS 9. I ran firmware updater under classic and it said it could not be run. I have been working a site right now, so I can't devote the time to restarting in OS9 and trying this, until the site is finished...



It is no big deal. I am trying not to run any classic programs for the time being or any haxies on the system. I haven't had any problems. I will try what you suggested, honest...



I appreciate your input, I really do. Is there a way to check the firmware without using the update? I know I updated it a while ago, but I can't remember when. System Profiler didn't seem to generate the firmware as part of its data collection.

algol

System Profiler lists the firmware version under the Boot Rom. And it looks like you're screwed! I would call apple up if I were you.

nosey

System firmware is 3.1.1. There haven't been any updates since July of 2001, when I did it last. There is updated firmware for the imac, but I don't think it would work on a BWG3.



The system appears stable. Some ninny I lent it to set the speed to 375mhz, and I have since turned on journalling. No haxies and we wait and see...



Thanks to everyone for the constructive technical assistance. I shall keep you posted.
