JSI Tip 0010 - Changing the default install path.

If you want to change where NT expects to find the NT CD, edit:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Sourcepath
and
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Sourcepath

If your CD drive is D: and you are working with an Intel-based machine, the value should be D:\I386 and D:\ respectively.
