Yea, add this line to '/etc/fstab' :
Code:
/dev/hda4 /mnt/windows vfat umask=000 0 0
Edit: Of course change '/dev/hda4' to wherever windows actually is and '/mnt/windows' to wherever you want it to mount.
And if don't want to restart your computer before it will mount, just type 'mount /mnt/windows'
