A Radeon 7000 Mac ed. (32 MB) would be the cheapest replacement video card, it will let you run both OS 9 and OS X up through 10.4.11 --~--~-~--~~~---~--~~ 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.

When I did an Xorg -probeonly it only saw the internal ATI, so I suspect if it can't see it, it can't use it. I did set up BootX to use the MSI driver, so I don;t think that's the issue. I found someone's xorg.conf file for the Twin Turbo, and tried using it, forcing Xorg to use the hardware by setting the BusID to the ID the MSI card had in lspci. Still no go, Xorg claimed it couldn't find a valid configuration and croaked (well, fell back into Ubuntu's "low graphics" mode, which is essentially the same thing since the screen remains blank). I eventually gave up on Linux and moved on to OS X, because all of the sources of info I found were saying that even if you got Xorg running with the IMS card, it would break if you looked at it funny. I'd prefer to hand off a more robust system to someone else. (That, and handing the system over to a Linux newbie would cause issues when they tried to install a kernel upgrade package, and thus cause BootX issues...) I need to get rid of the system soon... I'll look into getting the adapter, but if I can't get one in short order, I'll just have to reformat it using OS 9.1 and call it a day. Thanks for the help!

As to Linux have you tried having Xorg configure itself? If it isn't running a shell after boot you need to put a "1" in as kernel parameter to force it into a shell. Get the man page for Xorg and look for the command line argument to self configure it. Then run Xorg with that argument. If that doesn't do it then you will need to create or modify the Xorg configuration file.

Fuggedaboutit. The IMS card flat out will not run in OS X. Vastly less hassle to simply get a $10 Mac-VGA converter; ask on the LEM Swaplist. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs --~--~-~--~~~---~--~~ 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.

Beige G3 - disable internal video
I'm at my wit's end with this beige G3 (300 Mhz, 30GB IDE hard disk, 384MB RAM) that I've been prepping to give away. I've tried installing both Linux and OS X 10.3 on it, but run into what seems to be the same roadblock. The video card on it is an IMS Twin Turbo, which I need to use since it has a VGA out port on it, and I don't have any sort of adapter to convert the native Mac video out to VGA. OS 9.1 is peachy keen using the twin turbo's VGA out, but other operating systems seem to insist on ignoring the PCI video card and just use the internal video. Trying to boot into OS X results in the gray Apple logo with the spinny thing showing up onscreen as it boots up, but then that freezes. Eventually I hear the happy "Welcome to OS X for the first time" music playing, letting me know that OS X has booted up. And I swear it plays it in a very mocking manner. This g3 is very close to being defenestrated, and then immolated. I'm assuming that the problem here is that at the last moment, OS X decides that it's going to use the internal video and ignore the PCI card. Similarly, I couldn't get Linux to use the twin turbo, even if it kinda sorta saw that it was there. Xorg just refuses to use the PCI card, instead firing up the internal ATI graphics. I've pushed the CUDA button, zapped PRAM multiple times, and tried using the Open Firmware to set the pci-probe-list value to fffb, which a number of sites on the net say is the way to force the G3 to look to the PCI bus instead of internally for the video card. This last bit doesn't seem to take, however... if I use printenv, the pci- probe-list value stays stuck at the default value of -1. Do I have to somehow unlock Open Firmware's ability to set the pci- probe-list values? Is there some other way to force the G3 to ignore the internal graphics and use the PCI card? --~--~-~--~~~---~--~~ 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.
