[Wine] Redirecting the c: drive from .../drive_c?

[Godfrey]

I have windows xp installed on another partition on my computer. When it is mounted it shows in /media/Pirate (Pirate is the name of the drive.) is there anyway to make this the default c: directory in stead of .../dive_c? that way i can use all the programs installed on there without having to worry about the missing *.dll files. I want it to be the default c:, not d:, e:, f:, etc.
