Drive Letter Problem - Vista Installation

All,
I was wondering if anyone knows how to install Vista where the OS
partition uses the D: Letter and not C:

I normally install my OS as fallows:
C: temp directory (page File) (Primary Partition) (Fat32)
D: Windows Directory (Logical Drive) (NTFS)
E: Programs (Logical Drive) (NTFS)
F: Data Files (Logical Drive) (NTFS)

I've gotten use to this structure and would like to continue it...
however when I did my first install of Vista (I did it from my WinXP
installation) Vista took the drive letter I had temporarily assigned
the partition Z:. My second attempt was booting to the setup disk but
Vista took the C: drive Letter and assigned the Primary Partition a
drive letter of D:.

I would like the install to be as followes:
C: temp directory (page File) (Primary Partition) (Fat32)
D: Vista Directory (Logical Drive) (NTFS)

I realize this is a little anal but... If anyone can help it will be
much appreciated. Thanks in advance. - CES
