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, and onfigure a test system to boot using the EFI boot image. 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";

          host example-ia32 {
                  hardware ethernet XX:YY:ZZ:11:22:33;
  1. Add a config file. A sample configfile at /var/lib/tftpboot/X86PC/UNDI/pxelinux/efidefault might look like:
title Fedora
        root (nd)
        kernel /rawhide-i386.vmlinuz
        initrd /rawhide-i386.initrd.img
  1. Copy the splash image into your tftp root directory:
    cp /boot/grub/splash.xpm.gz /var/lib/tftpboot/X86PC/UNDI/pxelinux/splash.xpm.gz
  2. Copy a the kernel and initrd to /var/lib/tftpboot/X86PC/UNDI/pxelinux/rawhide-i386.vmlinuz and /var/lib/tftpboot/X86PC/UNDI/pxelinux/rawhide-i386.initrd.img
  3. 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
