I have been struggling with system 8.6 on my 6100 for some time now. I finally decided to check with the 1st-powermacs list for help. I can't run any of my collection of web browsers for more than 15 or 20 minutes without getting the "XYZ has unexpectedly quit. You should save your work..." message. I also get frequent errors of type 1 and some type 2.

I have IE5.1.6, Communicator 4.79, Mozilla 1.0, and iCab 2.9.8. I did the Text Encoding Converter update to 1.5, as the iCab readme recommends. Other than that I am running on a freshly reformatted hard drive and a freshly installed copy of 8.6. IThe system is from an OEM 8.5 disk, and then the downloadable 8.6 update was run. This 6100 has a Sonnet 400MHz G3 and 256 Mb RAM installed. It has always run well on 8.1 or 7.6.1, but has been flaky since I have upgraded to OS 8.6.

Run Disk First Aid. Ensure there are no problems on any of your volumes.

I just did a complete re-formatting, including the low-level format, ran disk first aid and drive set-up versions supplied with the 8.5 installer disk, and a clean and complete recommended easy install of 8.5 and the 8.6 upgrade. If anything, the flakiness has gotten worse asince the clean install.



Memory cdev settings?

If you mean by cdev the memory control panel, virtual memory is turned on, set at 1Mb more than actual RAM, the disk cahe is at default setting of 8 Mb, and a RAM disk is also present, set at 13 Mb.



What version of CarbonLib do you have installed?

That is a good question. I had previously installed a version more recent than waht comes with teh 8.6 installer. Maybe this is part of why things seem even worse after the clean install. I looked in the extensions folder and system flder and can find no CarbonLib at all. Sherlock doesn't find it in the internal drive either. I used to have 1.6, and there was also a 1.3.1 version on one of the other partions of trhe external drive, probably frm the system 9.1 install.



If you're touching any web pages that contain Flash, at any time, what version of Flash do you have installed?

Just the version 5 Flash Player that comes with Communicator 4.79.


Try this:

I will download and install MacsBug soon. In the meantime, responses continue below.



Install MacsBug. Download it from <http://developer.apple.com/tools/debuggers/MacsBug/> Decompress the archive. Drag MacsBug itself to your System Folder. Ignore the rest of the stuff in the archive. Eliminate as many 3rd party extensions and control panels as you can. Drag 'em to the desktop or use an extensions manager. Trash the following from your system Preferences folder: iCab Cache (within iCab Preferences) Navigation Services Open Transport Preferences Empty the trash. Reboot. Set iCab to its default preferred memory size of 3000K. Use iCab until you crash into MacsBug. Within MacsBug, do a "stdlog" then "ES". If the ES fails, do "RS". If the RS fails, do "RB". Email the stdlog to me. I'll take a look. :)

One thing that might be significant - I have 9.1 istalled on a partition of an external hard drive. When I first installed 9.1 it tried to "take over" the machine and somehow made it difficult to select the 8.1 system folder on the internal hard drive as the startup disk.

I had the same thing happen on my 7300 when I had multiple OSeseses. There is a bug, not fixed until OS 9.2, whereby the Startup Disk control panel fails to fully change the drive:volume boot pair in the PRAM. Very annoying.

This _is_ interesting. It would explain why I keep hearing drive access activity on the external drive, where 9.1, 8.1, and 7.6.1 system folders exist on separate partitions. And why some of the error codes I get involve the bus (that is no. 1, I think).
Thing is when all I had were 7.6.1, and 8.1, there were no problems. Then I skipped up to 9.1 and it seemed like it took many restarts before I could get any other disk (partition) besides the one with 9.1 to work as the start up volume. Then I decided 9.1 was not a good idea and installed 8.6, hoping that would be the best compromise between the old and the new.



Try zapping your parameter RAM. That fixes it temporarily, usually.

I haven't done that recently, but if it is just a temporary fix, then my quest is not over.


Do you think I should just entirely trash that 9.1 system folder on the external drive? Will that help make this stop, or does 8.6 also have the boot pair problem? I have not yet had 8.6 installed without 9.1 having been in the background.


HTH, - Dan.

Thanks Dan! Lots of good suggestions. I will let you know if I find some solutions among them
