This test validates booting EFI images over the network. Tests must be executed on a system capable of supporting Features/EFI. This test requires access to (or configuration of) a DHCP and tftp server to modify network boot configuration (see

How to test

  1. Copy the EFI boot images into your tftp root directory:
    • For i386 images:
      cp /boot/efi/EFI/redhat/grub.efi /var/lib/tftpboot/X86PC/UNDI/pxelinux/bootia32.efi 
    • For x86_64 images:
      cp /boot/efi/EFI/redhat/grub.efi /var/lib/tftpboot/X86PC/UNDI/pxelinux/bootx64.efi 
  2. Configure your dhcpd server to use the EFI boot images packaged with grub. A sample configuration in /etc/dhcpd.conf might look like:
  option space PXE;
  option PXE.mtftp-ip    code 1 = ip-address;
  option PXE.mtftp-cport code 2 = unsigned integer 16;
  option PXE.mtftp-sport code 3 = unsigned integer 16;
  option PXE.mtftp-tmout code 4 = unsigned integer 8;
  option PXE.mtftp-delay code 5 = unsigned integer 8;

  subnet netmask {
          option routers;

          class "pxeclients" {
                  match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
                  if option arch = 00:02 {
                          filename "ia64/elilo.efi";
                  } else if option arch = 00:06 {
                          filename "X86PC/UNDI/pxelinux/bootia32.efi";
                  } else if option arch = 00:07 {
                          filename "X86PC/UNDI/pxelinux/bootx64.efi";
                  } else {
                          filename "X86PC/UNDI/pxelinux/pxelinux.0";
  1. Configure a test system to boot using the EFI boot image. A sample host configuration might look like:
    host example-ia32 {
        hardware ethernet XX:YY:ZZ:11:22:33;
        filename "/pxelinux/bootia32.efi;

    host example-x64 {
        hardware ethernet XX:YY:ZZ:33:22:11;
        filename "/pxelinux/bootx64.efi;
  1. Reboot the system under test. When offered, be sure to select the network device as your boot device.

Expected Results

  1. The system should boot into the installer without error
