This is a known issue: <http://docs.info.apple.com/article.html?artnum=25564> It's been written about extensively on the Apple Discussion>Older Hardware>Beige G3 section. There really aren't any good solutions for the Bondi because it lacks any way to add a Radeon video card, which is the normal solution for this issue that affects the built-in Rage video only. You have too little RAM in the Bondi for using OS X effectively. One possible solution is to stop upgrading at 10.2.6 because it was a video system overhaul that effects 10.2.8 forward thru 10.4.11. Also, if you had more RAM this would probably make the black screen lockup occur MUCH less often because the causal factor has something to do with the way the video interacts with the HD read/write activity. The harder the HD is working, the more likely to experience the black screen lockup. You need a lot of HD freespace for OS X, and at least 2GB freespace for Jaguar. If you have less freespace, the HD will work harder and cause this issue more often. There is NO solution to the lockup other than a restart, normally a Force Restart using the Ctl-Cmd-Pwr keys. With max RAM, and perhaps a HD with a larger buffer or higher speed, you'd probably minimize the HD read/write cycles so the black screen would occur less often. On a Beige G3 with over 512MB RAM and 10.4.11 the black screen lockup would occur about once-per- week with 4-8 hours usage per day. Also, if your Bondi only has the 2MB VRAM, get the option 4MB VRAM chip to up the VRAM to the max. 6MB. Hope this helps a little, but there really isn't any totally good solution. You can only minimize the occurrence. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
