Re: problems with AGP video in sawtooth
The sleep problem is common to certain flashed cards,I have a 6200 card and it has the same problem, as probably every flashed 6200. About the other problems: First of all,are you sure you have a sawtooth?I ask this because,I though I had a sawtooth (400MHz single G4) and in fact I have a Gigabit Ethernet (with the small adc connector on the board) and if it is your case you must tape pins 3 and 11 on the card... Keep in mind that some cards have problems with MacOS X under 10.4.3 and take a lot of time too boot to 10.5 because of temp sensors (the case of my 6200). I know this are kinda neewbie advices for a guy that have flashed some cards,but you never know :) -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

problems with AGP video in sawtooth
i have been experimenting with a sawtooth i picked up a few weeks ago. i have flashed several AGP video cards (all nVidia) i have in my parts bin. what i find is that it usually takes several (2-4) attempts to boot properly. the behavior of the monitor in a normal boot sequence is: gray apple screen with spinning gear wheel light blue screen for 2-3 seconds slightly darker blue screen for 1-2 seconds yet again slightly darker blue screen with arrow cursor in top right corner, for 1-2 seconds then normal desktop appears. when the agp cards don't boot properly, they display the gray apple screen, then hang at the first blue screen. sometimes i get the kernel panic screen after 5-10 seconds on the blue screen, other times it just hangs at the blue screen. for the cards where the Mac rom supports DVI, it makes no difference to the proper booting whether i'm using DVI or VGA output. eventually, after several resets, the machine boots properly. i flashed an nvidia 5500 PCI card, which boots flawlessly every time, but when the computer sleeps, the video card won't wake up. when using any of the agp cards (after proper booting) the computer sleeps and wakes properly. any ideas? thanks!! ken -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Have you been resetting the power manager and/or zapping the PRAM after switching video cards? the behavior of the monitor in a normal boot sequence is: gray apple screen with spinning gear wheel light blue screen for 2-3 seconds slightly darker blue screen for 1-2 seconds yet again slightly darker blue screen with arrow cursor in top right corner, for 1-2 seconds then normal desktop appears. when the agp cards don't boot properly, they display the gray apple screen, then hang at the first blue screen. sometimes i get the kernel panic screen after 5-10 seconds on the blue screen, other times it just hangs at the blue screen. for the cards where the Mac rom supports DVI, it makes no difference to the proper booting whether i'm using DVI or VGA output. Sounds like the system is not identifying the video card properly, and loading the right kernel extensions right off the bat. The video info is cached in the nvram. So... After you install the card, press the CUDA button ONCE to reset the Power Manager. Then, when you boot, zap the pram. i flashed an nvidia 5500 PCI card, which boots flawlessly every time, but when the computer sleeps, the video card won't wake up. when using any of the agp cards (after proper booting) the computer sleeps and wakes properly. Check the system.log for errors.
