What should the BIOS boot order for compute nodes be?

Configuration
This is only an issue for machines that support network booting (also called PXE). In this case the boot order should be cdrom, floppy, hard disk, network. This means on bare hardware the first boot will network boot as no OS is installed on the hard disk. This PXE boot will load the Red Hat installation kernel and install the node just as if the node were booted with the Rocks CD. If you select the boot order to place PXE before hard disk to node will repeatedly re-install itself.
