-1. The PXE client software that comes with VirtualBox VM firmware **DOES NOT** support HTTP as a download protocol, so it may be best to leave iPXE disabled in `/etc/cobbler/settings.yaml`
-
-    - HTTP can always be utilized if you boot the PXE client from CD using the latest [ipxe.iso](https://boot.ipxe.org/ipxe.iso)
-
 1. By default, Cobbler's DHCP server attempts to detect the PXE client's boot firmware type in order to provide a BIOS or UEFI compatible bootloader *(BIOS: "grub.0" - UEFI: "grubx64.efi")*. If using **BIOS firmware** for the PXE client VM, the Cobbler server's DHCP service may not provide the right bootloader.
 
     1. manually set the bootloader for a Cobbler Profile or System with the following command (the `filename` value corresponds to the `filename` variable for the Cobbler System in the generated `dhcpd.conf` file, and is a local system path to the desired bootloader file relative to Cobbler's tftp root directory: `/var/lib/tftpboot`):
