Dell OptiPlex GX620 Windows 7 drivers

Dell do not make any Windows 7 drivers available for the OptiPlex GX620 even though this machine is still a perfectly capable workstation. Where I work they make up most of our inventory and they are all being upgraded to 3GB of RAM ready for the roll-out. The Pentium D CPU runs in x64 mode, and even the Pentium 4 HT 3.40GHz sold in early configs is 64bit capable.

Windows 7 includes a driver for the Intel 945G integrated video card, though Windows Update will suggest a newer one. There is an issue with this (see my post for details), so you should use version 8.15.10.1912 instead which you can find at Microsoft Update Catalog using a search string of Intel 82945G Express and sorting by version number. You’ll need to use Internet Explorer because it requires an ActiveX control to be installed.  Download both of the two matches – one is x86, the other x64 but you can’t tell them apart until they are downloaded.

The SoundMAX Integrated Audio is detected and installed by Windows Update, but if you’re maintaining a WIM image or building an unattended install you’ll need to isolate the driver files. These are also available at Microsoft Update Catalog – search for SoundMAX Integrated Digital Audio, order by version and look for version 5.12.2.7010 for x64 and 5.12.1.7010 for x86.

Customizing Windows 7 unattend.xml

Windows 7, like Vista, uses an XML answer file to configure the OS install. What’s neat about this is that even though you use the WAIK‘s WSIM tool to edit and validate it, you can customize it and add your own sections for software packages etc. as you can see from the example below, though these custom sections will need to be inserted after the sections that WSIM validates. This answer file can easily be parsed with VBScript using MSXML DOM, allowing for variables like passwords, driver sets, product keys and so on to be inserted at build time.

Why use an unattended install?

If you’ve always used an unattended install to build your workstations, you’ll know that they can be extremely versatile. If you already have a scripted build for XP with applications then chances are you’ll want to tweak those scripts to work with Windows 7. Sure, Sysprep images are handy too, but unless all your machines are the same, or all your packaged app requirements are identical, then you’ll need to add a load of scripted customization to them anyway. Which begs the question: why not just use an unattended install? That way you eliminate application problems that sometimes surface after image-based deployment. In a previous job I remember Roxio deployment in particular was a nightmare for this reason.

Microsoft have certainly made things considerably easier with the release of the Microsoft Deployment Toolkit 2010 but, though it offers a great introduction into the process of automated system building, it lacks the flexibility of rolling your own build process – in particular if you already have a host database. When I decide to rebuild a machine, it boots Windows PE from WDS, looks up its MAC address in the host database and reads the model type from WMI and will offer default choices in my build script menus based on that. It also works out which is the nearest site file server to use for the install.

The problem with Sysprep deployment if you have a very mixed hardware environment is that you either have to:

  • Create a WIM image for each different hardware type (lots of boring maintenance when changes are required)
  • Add a huge bulk of drivers to a single WIM image with DISM
  • Use the AuditSystem phase to connect to a driver share and re-detect all the hardware

Since Windows Vista and later versions effectively just install a WIM and run a hardware detection phase during their normal install process, Sysprep no longer offers much of a speed improvement over an unattended build.

Device drivers

Additional mass storage and networking drivers that will be essential during setup are detected in the Windows PE instance (which we booted from WDS) Driver Store and ‘reflected’ into the installed OS. As you build your custom Windows PE boot image, add these using DSIM as described in my post on the subject.

Since we can read the PC model name from the BIOS via WMI, we can add a tailored device path to the offlineServicing phase of setup. This allows for easy maintenance of driver bundles, since we can arrange them by model type (which certainly beats having dozens of SoundMAX audio drivers lumped together), and we can limit which drivers are offered to each model – particularly useful when a driver causes problems for some models, as with the GMA950 driver and Adobe Flash on Intel 945G motherboards.

I noticed that this is in fact considerably neater that the method used in MDT2010’s ZTIDrivers.wsf script, which copies drivers to the local system then invokes the AuditSystem phase, running the PnP detection routines a second time, slowing down the install. Useful for an OEM like Dell I suppose, whose PCs are often started from their factory image with no connectivity, but not ideal for corporate LANs.

Sample autounattend.xml with custom sections at the end

Note 1 – I couldn’t find any examples of this online, but I discovered that the values for pre-populating the Internet Explorer 8 Search Providers can be obtained by configuring a workstation, then harvesting the registry settings from HKCU\Software\Microsoft\Internet Explorer\SearchScopes. I have highlighted the relevant lines in the XML below.

Note 2 – Somewhat confusingly, in the offlineServicing phase Microsoft-Windows-PnpCustomizationsNonWinPE will fail to connect to your file server for drivers unless you connect to its FQDN (assuming the unattended launched the OS build from a share referencing just the NetBIOS name). Fail to do this and %systemroot%\panther\setupact.log will reveal that it fails to connect with error 0x4C3 (multiple credentials on connection to the same server). What’s bizarre is that there certainly aren’t multiple credentials in use – I use the same ones throughout. I wrote up this problem and solution in this thread on the MSFN Forums. I suspect this might be caused because I launch setup.exe from a network drive rather than mounting the OS WIM image from a WDS server (I wanted to maintain consistency with my other legacy OS builds). I have highlighted this on line 57.
