recovery console install not to C drive

A recent post on one of the Tech Republic newsletters described the procedure to install the recovery console for Win XP. This is a pretty straight forward process, and has been described elsewhere (Mark Minasi Win XP Pro, among others).
Unfortunately, the process described seems to be flawed or incomplete, since the directory, \cmdcons, is installed on the C: drive. I have been unable to discover a way to be able to specify the volume where this directory gets installed. It doesn’t work, in my experience, to copy the directory to a different drive (in this case I want it on the D: drive which is my system drive). Someone pointed out that the boot.ini file needed to be changed, but that was the first thing I did after I copied the \cmdcons directory to the D: drive. It didn’t make any difference. Any thoughts?
