Bug in Catalyst 4.8 Renders W2K System Unusable
I'm experiencing a strange bug in Catalyst 4.8 and I need help working
around it. I was using MS FS2004 in full screen mode and decided to go to windowed mode, then change the anti alias settings from 4x to 2x. I brought up the ATI command center, and to my surprise the anti-alias setting was at "application preference". I never allow that setting. I had definitely explicitly selected 4x. I deselected application preference, then manually selected 2x, then selected Apply. The screen went blank. Now after Windows desktop finishes drawing, the screen goes blank every time I reboot. This strange sequence with anti aliasing has put the RADEON 9800 Pro adapter settings into some undefined state I guess. I am in a Catch 22 now, because I cannot run the ATI uninstall unless I am able to login to Windows 2000, which I cannot do. I tried to use Terminal Services to login remotely, but that uses its own graphics driver, and the ATI uninstaller refuses to work. I tried to use safe mode, but similarly the ATI uninstaller refuses to work. I tried installing Catalyst 4.9 but that seems to be inheriting the buggy settings, and now when I login the monitor goes blank. I'm sure if I could just run the uininstaller I could reset things and install from scratch, but I don't see a way to do it at this point. How can I reset my system and remove the ATI RADEON driver settings from my registry? -- Will westes AT earthbroadcast.com |

I don't remember ... can W2k be rolled back, or booted
into the "last good ... "? As a last resort, I've actually gone in and manually deleted the offending folder. W2k would come back with all kinds of "can't finds", but then I could get in, and reinstall drivers. If you can get in .. in safe mode, then the driver is the problem. It can't load if it is not there. Best defense against this is disk imaging. I sure do like mine. Saves me from myself. johns |

safe mode in W2K?

Yes, W2K has an F8 option at boot time that lets you choose from several
different safe modes. -- Will westes AT earthbroadcast.com "First of One" wrote in message ... safe mode in W2K? -- "War is the continuation of politics by other means. It can therefore be said that politics is war without bloodshed while war is politics with bloodshed." |

Booting to the last good configuration doesn't help in this case. There
was never a blue screen of death, and Windows has no way to know the driver is displaying incorrectly. I think the issue is internal to the driver alone. Your idea about imaging is well taken, and I should get in the habit of disconnecting my mirror before any memory upgrade. -- Will westes AT earthbroadcast.com "johns" wrote in message ...

As an update to my post, I finally got into Windows during one boot and
tried to run the uninstaller, and it claims the ATI drivers are not installed!! -- Will westes AT earthbroadcast.com "CHANGE USERNAME TO westes" wrote in message ...

How can I reset my system and remove the ATI RADEON driver settings from my registry? This usually occurs ( blank screen on boot with ATI cards ) when Window puts the video card in a mode incompatible with your monitor... It happens alot to people with old monitors and WinXP, and you need to use the F8 - VGA Compatibility mode... ( Is there such an option in W2K? scratching head... ) FYI |

message ... As an update to my post, I finally got into Windows during one boot and tried to run the uninstaller, and it claims the ATI drivers are not installed!! This just keeps getting worse. To review, I invoked a very serious bug in the ATI Catalyst 4.8 drivers by running FS2004 in 1600x1200 full screen mode, with 4x FSAA, then: 1) Went to windows mode. My desktop runs at 2048x1536, and it is the difference between my desktop resolution and the game's full screen resolution that may somehow relate to the bug I have invoked. 2) Right clicked desktop, and changed FSAA from 4x to 2x. FS2004 was still running in its window. 3) At that point the screen disappears (goes black, but I do NOT lose the synch light on the monitor), and I haven't gotten back my ATI driver install to a stable configuration since. I had been using the RADEON 9800 Pro for over a year without significant problems. Now the update: - I found a trick to get back the screen when it disappears. I can login remotely using Microsoft Terminal Services, then use the ATI system gadget to set the desktop from my remote login. Strangely enough, the resolution I am setting affects only the console session, not the terminal session. I lower it to 1280x1024 and the screen appears again. So I've exploited a separate bug to help workaround the first one. - Once the bug of the disappearing screen happens, then the ATI drivers start to think they are no longer installed. Attempts to launch the control panel get: "No ATI graphics driver is installed, or the ATI driver is not functioning properly." I am launching the panel from 1280x1024 resolution, after recovering from the disappearing screen. - Even after recovering, when I reboot, I can never get the uinstaller to work properly. It always comes up with: "This action is only valid for products that are currently installed" Twenty seconds after getting this message, the ATI Control Panel icon disappears from my Windows desktop. Ten seconds later, I get a messge that I must restart my system for the changes to take effect!! So the uinstaller is just partially working. - Even when I can recover resolution and am careful not to reset any of the 3D settings that initially set off the problem, the screen is not drawing as fast as it used to. I can see the contents of individual child windows redrawing left to right across the window in sections, with small stutters between each section. Is it possible that when I first invoked the bug, that the ATI driver did something to permanently reprogram the hardware itself into a state from which the hardware cannot be recovered in software? Is there any way to hard reset the RADEON 9800 Pro hardware back to its factory configuration? For example, is there a jumper I can place on it, or take off, that would reset its internal programming? -- Will westes AT earthbroadcast.com |

I had been using the RADEON 9800 Pro for over a year without significant problems. You need to use a driver cleaner to clean the registry entries so that the new driver install doesn't inherit the bad settings, and as I said before you need to use the F8 safe mode option to force VGA compatibility mode ( I think it temporarily forces the VESA driver on ) to bypass the bad video card settings in the registry. |
