+[[!meta title="full page title"]] Setting up Swapcache
+
+This page was created from my notes of setting up my SSD as a swapchache.
+The I used the Intel 40 GB X25-V SATA II MLC.
+
+[[!toc]]
+
+# Formatting new drive for swap
+
+After you install your dive you should be able to find it from dmesg.
+For the Intel just grep on INTEL
+
+    # dmesg | grep  INTEL
+    ad6: 38166MB <INTEL SSDSA2M040G2GC 2CV102HB> at ata3-master SATA150
+
+So our new drive is ad6.
+Now setup to the drive [[!color  foreground=red text="**If you choose the wrong device you might/WILL destroy all your data on that disk.**"]]
+
+    # dd if=/dev/zero of=/dev/ad6 bs=1k count=1
+    # fdisk -BI ad6
+    # disklabel64 -B -w -r ad6s1 auto
+    # disklabel64 -e ad6s1
+
+Now you should be in your editor with the disklabel data.
+Arrow down to the bottom of the screen.
+You should see some sample labels
+
+    # EXAMPLE
+    #a:          4g          0    4.2BSD
+    #a:          *           *    4.2BSD
+
+After the last line add :
+
+    b: *       0       swap
+
+Now save the file.
+
+Create a new file system on your drive.
+
+    # newfs /dev/ad6s1b
+
+# Adding Disk to fstab
+
+Edit /etc/fstab and comment out any exisiting swap partitions. Just add a # in front of the line.
+
+    # /dev/serno/JPC550HN25.s1b          none            swap    sw              0       0
+
+Add your new device to fstab
+
+    /dev/ad6s1b          none            swap    sw              0       0
+
+# Setting swapcache to start on boot
+
+To enable swapcache on boot edit etc/sysctl.conf and add
+
+    vm.swapcache.read_enable=1
+    vm.swapcache.meta_enable=1
+    vm.swapcache.data_enable=1
+
+See [swapcache(8)](http://leaf.dragonflybsd.org/cgi/web-man?command#swapcache&section8) for other sysctl options.
+
+# Activating the swapcache
+
+The easiest way at this point is to just reboot the machine.
