+You can [[:embed]] a script within iPXE to override its default behaviour.  For example, you may wish to build a version of iPXE containing an [[:embed|embedded script]] that uses DHCP to obtain an IP address but then boots from a predefined SAN target.

-==== Embedded scripts ====
-You can embed a script within iPXE to override its default behaviour.((When you embed a script, you will no longer see the "Press Ctrl-B for the iPXE command line" prompt at startup or if booting fails.  If you wish, you can provide your own replacement prompt using the ''[[:cmd:prompt]]'' command.))  For example, if you want to obtain an IP address using DHCP but then always boot from a fixed URL (ignoring any boot filename provided by DHCP), then you could embed a script such as:
-    #!ipxe
-    dhcp
-    chain http://bootserver/boot.php?asset=${asset}
-To embed this script within iPXE, add ''EMBED=<script>'' when you [[:download|build]] iPXE.  For example, to embed a script saved as ''myscript.ipxe'' into a [[:howto:chainloading|chainloadable]] iPXE image:
-    make bin/undionly.kpxe EMBED=myscript.ipxe
