Hardware recognition issue

[Deon Schaffer]

I have been running beta and RC versions of Windows 7 x64 for about 9 months now.

A few weeks ago, I needed to run a seperate copy of Win7 on the same machine so I decided to take the VHD route. I.e. booting directly into a VHD. The means to do this were well documented by Aviraj Ajgekar's block @: Link Removed

The problem began once I attempted to install Windows 7 x64 RTM. For some reason, the hardware recognition is having some issues, most significantly - the display adapter. In the past, the pre-RTM versions recognized the hardware without any issues.

One of the actions that I had to perform as part of the boot to VHD option was to set the DETECTHAL option to ON.
(Please see the link above for more details.)

I have no idea if this is related to the problem or not but no matter what I do, I am still stuck with a "Standard VGA Graphics Adapter" instead on my NVIDIA Quadro 570M.

Any ideas?

It sounds like Windows 7 RTM isn’t recognizing your Quadro 570M and is defaulting to the generic VGA driver. Here are some steps and considerations that might help narrow down the issue:

• Driver Installation: • Verify that you have the proper drivers installed for your NVIDIA Quadro 570M. Often a “Standard VGA Graphics Adapter” indicates that Windows is simply using its fallback driver because it can’t find or load the specific driver. • Go to NVIDIA’s website and download the latest Windows 7 x64 drivers for your Quadro series. Sometimes Windows Update isn’t keen on pushing the right drivers for these devices.
• Impact of DETECTHAL: • Since you set DETECTHAL to ON for your boot-to-VHD configuration, consider that this might be affecting how the HAL is interacting with your hardware. In past beta/RC builds things may have “worked” even with that option enabled, but the final RTM might be more sensitive. • As a test, you could try booting without DETECTHAL set to see if the hardware detection improves (after ensuring you have backups and a recovery plan, of course).
• VHD Boot Considerations: • Running a system off a VHD can sometimes lead to unexpected behavior, especially if the final build handles certain hardware queries differently than the pre-RTM builds you were running previously. • Double-check the VHD configuration and ensure that there aren’t any limitations or misconfigurations causing Windows to “see” a different hardware profile or not load the proper driver.
• BIOS/UEFI Settings: • Ensure your BIOS/UEFI firmware is up to date and that any settings related to graphics (like integrated vs. discrete display options) are configured correctly. Sometimes a firmware update or setting can affect how Windows detects and loads drivers.
• Windows Update: • Make sure Windows Update has been fully run since the RTM installation. Occasionally, updates delivered post-RTM (or via the Windows Update catalog) include critical fixes that enhance hardware detection and driver deployment.

In short, focus on updating or reinstalling the correct NVIDIA drivers (preferably from the vendor’s site) and look at the DETECTHAL setting to see if it might be interfering with proper hardware detection on RTM. If the issue persists, consider testing the installation on a non-VHD setup if possible, to isolate whether the problem is tied to booting from a VHD.
Hope this helps! Feel free to share any additional details or follow-up questions if you need further assistance.
