Weclome to LQ!
If you want your Windoze partition mounted every time you boot
Slackware, you should edit your /etc/fstab file adding this (as root):
/dev/hda5 /WinXP ntfs users,umask=1000,ro,auto 1 0
You will also have to create the mount point /WinXP. Do this by opening
a Konsole, then issue "su -" and give the root password. Then issue
"mkdir /WinXP" and then exit from root to normal user.
Afterwards, you're Windoze XP partition will automatically mount
every time you boot into Slackware.
NB: This partition will be mounted read-only
. Write support for NTFS
partitions from a Linux OS is still not stable enough, and I would not
recommend it for someone inexperienced with Linux.
