Just noticed I should add something on the wiki about pxechn.c32, a
replacement for pxechain.com.

One benefit is that if you have the dhcpd pointing the field 'siaddr'
to a non-WDS tftpd that is used for PXELINUX with a WDS on Windows
Server 2008R2 (and likely newer), the '-W' option allows you to
chainload the WDS's boot file wdsnbp.com.  Without it, it'll try to do
its own DHCP and then search for WDS files on the non-WDS tftpd.
However, using gPXE/iPXE will break this (at least with
gpxelinux.0/ipxelinux.0) last I checked.
