make a directory on your linux partition in which you would like to acccess windows XP through, for example "/mnt/winxp". Mount the filesystem to that directory with the command:
QUOTE
mount -t ntfs /dev/hda1 /mnt/winxp
Provided that /dev/hda1 is the partition for your windows XP drive. This will mount the drive as read-only and accessable only by root. There are methods of mounting it so it can be accessed by users, but you need to refer to the "man mount" man page for the information.
