For each drive letter that is defined in your system, DOS sets aside an 88
byte block of memory to store info about the associated logical drive.  The
block is called the CDS, current directory structure, which tells DOS what
the current directory for the drive is, where DOS can find info about the
drive's physical characteristics, and whether the drive is a network drive.

So, with that in mind, you can see the difficulty in trying to change the
lastdrive environment variable; since DOS allocates the memory needed to
store environment information about drives when it reads config.sys file
on boot-up.  So, to my knowledge, you can't change the lastdrive after
the system starts.  Let me know if you find a way around this, though.
