HD Install :: Problem with swap partition

I install DSL on my hdd.I have 2 partition: 1st is hda2 with ext2 fs and 2nd is hda5 swap.After the install DSL don't want to mount the swap partition and displays:

Quote

mount: can't find /dev/hda5 /mnt/hda5 in /etc/fstab or /etc/mtab unmount: /mnt/hda5 /mnt/hda5: not found

The fstab looks like this:

Quote

/dev/hda2 / ext2 defaults,errors=remount-ro 0 1 proc /proc proc defaults 0 0 /dev/fd0 /floppy vfat default,user,noauto,showexec,umask=022 0 0 /dev/cdrom /cdrom iso9660 defaults,ro,user,noexec,noauto 0 0 #partitions found by dsl #/dev/hda2 /mnt/hda2 auto,noauto,users,exec 0 0 #/dev/hda5 /mnt/hda5 auto,noauto,users,exec 0 0 #Added by KNOPPIX /dev/hda5 /mnt/hda5 auto noauto,users,exec 0 0

My pc:
CPU p133
