Right, I’ve told you about the issues with the AMD legacy driver. I also reported the issue to AMD technical support. I’m surprised they replied at all, but let’s go through their reply step-by-step, as it’s quite a good one:
Thank you for Contacting AMD
I understand that your legacy drivers for windows 7 not working properly.
If I missed any information about your issue please let me know, as my suggestions may change.
(Emphasis mine). Okay, so they understand that it’s about the legacy drivers, not the regular Catalyst drivers (which should be obvious, as I had to specifically select the Radeon X1900XTX 512 MB PCI-e card when filling out the form).
Your issue is probably caused by improper driver installation or missing / corrupt files or by trying to install the wrong driver.
The following suggestions might help you resolve your issue
1. Uninstall all ATI drivers and any other video card software from the Add or Remove Programs and Features in Microsoft, Control Panel
Okay, so far so good. The uninstaller apparently does not work properly, but hey.
2. Try using a driver cleaner program to make sure the drivers are removed: Please keep in mind that the (Driver Cleaner / Driver Sweeper are 3rd party software and not supported by AMD) please refer to their websites for instruction and guidance.
a. Driver Cleaner Professional
b. Driver Sweeper: http://downloads.guru3d.com/download.php?det=1655
Right, so because your uninstaller does not work properly, I have to resort to unsupported, unofficial third-party solutions?
3. Disable any running background software such as firewalls and antivirus.
Uhh, really now? Firstly, how is that going to help? And secondly, why are you putting your customer’s systems at risk like that? Especially since you don’t mention anywhere in the list that firewalls and antivirus should be re-enabled after a successful installation.
4. Make sure your operating System has the latest Service Packs and patches / updates.
5. Make sure your motherboard has the latest BIOS and CHIPSET (you can get these updates directly from the manufacturer of the motherboard or Computer)
I guess we can give them those, quite the standard procedure.
6. Make sure your power Supply is adequate
This one is again bordering on the ridiculous. If the power supply is inadequate, chances are you will be having much bigger problems than just getting a display driver installed.
7. Since you have a Windows then install this driver: http://support.amd.com/us/kbarticles/Pages/catalyst122precertifieddriver.aspx
Uhhhh… Didn’t we establish above that I have a Radeon X1900XTX, and need to install the legacy driver? This driver does not support my video card.
Well, the rest is just more standard procedure I suppose, I’ll just quote them for completeness:
8. If the problem still exists please try your video card in another PC or try another video card in your PC if possible.
9. Or test your hardware like RAM, CPU , USB devices…etc (make sure they do not create the problem
10. If the problem still exists please download the Belarc Advisor – a free system diagnostics, system information and benchmarking to create a problem report as described: In HTML format and attach file to e-mail. http://www.belarc.com/free_download.html
12. If you are looking for a specific driver, a list of previous drivers can be found here:
Except for point 11/12, where they once again redirect me to drivers that don’t support my videocard in the first place! I can only use the LEGACY DRIVERS, people! You invented that whole schizophrenic driver system, now deal with it!
I shall reply, and point out that they’re redirecting me to the wrong drivers, and also pose the question how I am ever going to get an older Radeon and a newer Radeon in the same system to both work with OpenGL with their broken driver design. The irony is that one of our development machines has two Radeon 4850 cards, and a third GeForce 7600GT card (only a single-slot card would fit in the third PCI-e slot of the machine, and the 7600GT was the only single-slot card we had at hand). And that setup actually DOES work. So you get better compatibility with Radeons and GeForces mixed than you do with a Radeon-only system? Just genius… Might also explain why we couldn’t get the video input working on the Radeon X1900 when we had multiple cards in the system. It probably has similar driver snafu’s.
