You would have to modify the "default" WINDOWS behavior of drive
letter assignments. (standard IDE layout, Normal hard drives only for
simplicity)

C: is the FIRST partition on the First (boot order) hard drive on the
FIRST channel.
D: is the FIRST drive partition of the FIRST drive (Master) on the
SECONDARY channel
E: is typically the SECOND (Slave) Drives First partition on the
Primary channel.
and so on.
Letters are First assigned to the first partition on all drives.
Then they are assigned to the second (if used) partition of each
drive.
Then the 3rd partitions (if used).
Then the 4th (I believe that 4 partitions is still the limit of the
partition table. I could be out of date :/ )

IIRC DOS does not recognize the reassigned drive lettering.
What might be a (resigned) D: in XP, might be E: in W98/DOS
