ati radeon drivers code 43 code 37 code 10

Hello,
I have been having quite a few difficulties with installing a Vista-compatible Radeon driver for a Radeon 9550 256MB AGP card.
I have tried the following: 1) default ATI Radeon 9550 driver (WDDM) -> code 43 (device reported problem) 2) Standard VGA driver -> code 10 (device cannot start) 3) ATI Radeon 9550 driver for Vista Beta 2 -> code 43 (device reported problem) 4) ATI Radeon 9550 driver for Vista Beta 1 -> code 37 (driver could not be initialised) 5) Catalyst 6.6 XP driver -> okay (but no Aero as it is not WDDM)
The Performance Rating and Tools section cannot detect the video card, nor gaming graphics. However, the ratings are 2.0 and 3.2, respectively.
The motherboard is a ASUS P4S8X-X with a SiS 648 chipset. I have tried replacing the default Vista AGP driver with a SiS XP driver, but it makes no difference.
I have reinstalled Vista Beta 2 onto a clean, formatted parition before installing each driver. I have also used the "Check for Solutions" utility, but so far, no solution has been found.
I have searched the Vista newgroups and the Internet, but the few solutions which I found did not work.
I realise this is a beta build, but it would be very nice to personally see what Aero looks like as there has been a lot of fuss about it.
Any help would be greatly appreciated.
Jake.

This isn't going to be of any help. It's just an observation really.
I have the same graphics card and Vista 2 installed and recognised the card without any problems.
My computer crashes every time I try to use Hibernate, yet others don't have the same problem.
Strange.
Graham.

I know most people don't have extra monitors hanging around but if you did, maybe try that. Is there a monitor installed in Device Manager during full boot. Can you install the default driver in Safe Mode *with* Networking and not get the error code. Uninstall the loaded driver first, then right click PC name and select Scan for hardware changes, let Windows load the driver it wants and see if it errors out there. You would not see the monitor loaded in device manager in safe mode. In safe mode you get to the device manager through Administrative Tools. If the driver settles in while in Safe Mode without error and then crashes when booting full into Vista you probably have a conflict with your monitor since you have the AGP drivers installed.

Thanks very much Bob for the tips.
I booted into safe mode with networking and uninstalled the ATI Radeon 9550 driver, and scanned for hardware changes. The same driver was automatically reinstalled. Device Manager showed both ATI Radeon 9550 (WDDM) and ATI Radeon 9550 Secondary (WDDM) with no errors. However, the reason both showed no problems was probably because the status of the video card is not reported in safe mode (I viewed the properties of each device and it said the status was unavailable in safe mode).
When I booted into Vista again, the code 43 error was displayed, and only ATI Radeon 9550 (WDDM) was shown in Device Manager (no secondary output was detected). The display reverts to something called "VGA Save".
Also, unfortunately, I do not have another monitor handy, but I am curious if it is possible to install a driver for a monitor in Vista. I have a Benq LCD monitor which has an XP driver, but I cannot find anywhere in Vista where the monitor driver can be installed. The "Add Hardware" wizard fails to install the monitor driver from the INF file, and there is nowhere to change monitor drivers in the Display Properties dialog (it's blanked out and no monitor name is displayed).

Hi Woody,
I downloaded the official ATI drivers for Vista Beta 2 from the link which you provided. I attempted to install the drivers using the setup application included with the package, and from the INF files. Both methods install the driver, but upon restarting, the code 43 error is displayed and the Radeon driver is not initialised.

Hi Graham,
The driver errors could be related to the chipset on the motherboard. I have an ASUS motherboard with a SiS 648 chipset. May I ask which motherboard you are using, and also, what monitor you are using? (Bob T. suggested the monitor may be causing the driver problems)
Thanks,
Jake.

VGA Save is a failsafe MS driver to get you some video. A monitor driver is not loading in the full OS for some reason. Your video driver is not loading. A problem I was having was with a Nvidia Gforce FX 5200 card and an incompatible monitor. Even though Vista had the monitor drivers. I loaded a Nvidia 256 driver and was able to finally get out of VGA Save and change a few things but was wrong config. Grabbed a monitor from the kid's puter, hooked that up, uninstalled everything, booted (with the 5200 drivers, the computer wouldn't even boot) everything loaded and correctly. So the kid gets my 19" monitor. "Jake" wrote in message

Hi Jake.
The motherboard is a Gigabyte 7VM400AM-RZ with a VIA KM400A chipset.
The monitor is a DELL 770S. Vista only reports it as a plug and play monitor.

Well, jake, i made the same post you did about this issue, tried the xp AGP to PCI brigde of my motherboard and nothing, i have a Giga-Byte K8nsnxp-939 Nforce 3 250 chipset, i did everything i know and don't know but its the same, the XP drivers works but no aero, i even downloaded the 5.26 (the previous beta drivers from ati) and nothing... I really want to see aero
I guess we should wait for better drivers or someone find a solution, if i found something i will post it

Hi Bob,
I hooked up a CRT monitor to replace the existing LCD monitor, and tried to boot into Vista again, but I am still receiving the code 43 error. I don't think Vista supports monitor drivers yet. In Personalize -> Display Settings, is (Default Monitor) shown? Or is a specific monitor listed?

Interestingly, I attempted to install a WDDM driver for a Radeon 9500 (not 9550). I rebooted, and Vista again reported code 43, just like the WDDM driver for the Radeon 9550. Even a wrong driver acts like the correct driver does.
However, Vista does correctly recognise that the video card as a Radeon 9550. It just always thinks the card has reported a problem.
The XP drivers work fine, so I don't think the AGP drivers could be the problem. The video card drivers seem to work fine for others, so I don't think the problem could lie with the WDDM drivers. So I am not quite sure what is causing this error.
It would be very interesting to see if anyone finds a solution.

Was worth a try. Some monitors have drivers ready. Mine did, hooked it up to an Unkown Device which luckily happened to be where it needed to go but it didn't work. Might want to see if your motherboard is loaded up correctly but I'm just phishin now. "Jake" wrote in message

If I can interject.
Many monitor problems in Vista can be fixed by using the generic LCD monitors (Add Hardware Manually........Show me a list etc etc). Just pick your monitor's max refresh rate and resolution and everything usually cleans itself up. Had the same problem with an Nvidia card until I realised that was the issue.
This was actually a problem I've always had with XP, because you can't pick max refresh rates for your generic LCD monitors, so my Nvidia card would jump to 1024 x 768 but at 200 Hz. Don't know about you, but I don't have a monitor that will support 200 Hz refresh rate LOL.

Jake,
Don't know if you've found a solution to this problem and interestingly enough no one else has reported a real solution either. I have a 9550 card too and what finally worked for me were the drivers from 2004 that came with the card's driver disk info follows:
Ati Technologies Inc. 7/10/2004 6.14.10.6458
These are digitally signed and remove the error 43 code. Also speeds up Vista a bit.
Hope this works for you too!
