When to use Specify path to $OEM$ directory
To define computer settings in a system package for Microsoft Windows operating system other than Windows 2008, you must specify whether your $OEM$ directory resides directly under the i386 or amd64 directory in the data store.
This information applies to Windows operating systems other than Windows 2008. To specify the location of Windows 2008 drivers, see Computer settings - Windows 2008.
If you do not check Specify path to $OEM$ directory, your $OEM$ directory (and the drivers it contains) must be located directly beneath the i386 or amd64 directory.
For example, assume your data store root is drive:\pxestore and you are storing your Windows 2003 operating system files in a directory called win2k3. Your $OEM$ directory and its contents must look similar to the following:
However, you might not want to store your drivers directly beneath the i386 or amd64 directory. Instead, you may want to store your drivers in a directory structure similar to the following:
In this case, check Specify path to $OEM$ directory and then specify the location of the $OEM$ directory in Path to $OEM$ directory. The path to the $OEM$ directory is from the root of the data store and does NOT include the $OEM$ directory itself. Continuing with this example, (where drive:\pxestore is the data store root), the Path to $OEM$ directory is: drivers\vendor1\model1
