DBAN 2.2 PXE howto
Get the latest DBAN iso image. Mount it and extract the dban.bzi file from it. The isolinux.cfg in the same location contains the default boot methods for DBAN for inclusion in the PXE config.
Place the dban.bzi file at tftpboot/dban/dban.bzi (on larch it is /var/lib/tftpboot/dban/dban.bzi). Add stanzas for the new kernel in your pxelinux config. tftpboot/boot-menu/utilstext.cfg on larch.
