How to disable a Ram Swap permanently

Hi Steve and All,

     In fact, I have added a line in /etc/fstab to install my Swap
Partition. The listing of my fstab is :

# /etc/fstab: static file system information.
proc            /proc           proc    defaults        0       0
UUID=5a715fd8-c9d0-4523-a213-eff956d2d798     /        ext3
errors=remount-ro     0     1
UUID=a5662716-31ad-4c28-abab-f0e323d5ae2c     none     swap     sw     0
0
/dev/scd0     /media/cdrom0     udf,iso9660     user,noauto,exec,utf8
0     0

     These settings in fstab install my Swap Partition with -1 priority and
would not let my Ram Swap go away.

     Any concrete procedure to disable the Ram Swap?

Regards
Lawrence
