1. less /proc/filesystems
If ntfs is listed, you have NTFS support. If not, go grab the appropriate RPM.

2. Make a mount point.
mkdir /mnt/windows
3. mount -t ntfs -o ro /dev/hda? /mnt/windows
Replace hda? with the partition that is your ntfs partition. The "-o ro" means read-only. Don't use write support unless you absolutely have to (i.e. an emergency).
