-=== Test ===
+== Configuration ==
+
+Before you boot SALI from tftp you first must configure the IMAGESERVER variable. SALI uses this variable to determine if your central image server is reachable. If this is not the case SALI will stop the startup process.
+
+There are two ways to configure this:
+ 1. Specify IMAGSERVER=<ip> in your pxe file as a KERNEL parameter
+ 2. Specify the ip of the imageserver in your dhcp configuration
+
+An example for isc dhcpd server
+{{{
+## Support for the SALI and the 'old' imageserver settings
+#
+option option-140 code 140 = text;
+option sali-imgsrv code 224 = ip-address;
+
+# Admin network
+#
+subnet 192.168.144.0 netmask 255.255.248.0 {
+  ##  option-140 is the IP address of your SystemImager server
+  #    sali-imgsrv is the new setting for the Systemimager server
+  #
+  option sali-imgsrv 192.168.146.10;
+  option option-140 "192.168.146.10";
+  next-server 192.168.146.10;
+....
+}
+}}}

+If you haven't change your dhcpd configuration to specify the variable IMAGESERVER you must add it to your pxe file.

 Reboot the node and if your node has a [http://en.wikipedia.org/wiki/Remote_access_card Remote Access Card] take over the console and see how the node boots. If the node has finished the boot process you can login on the node:
