Just set up ISC DHCP on fresh CentOS 7 install and followed the redhat guide linked in this thread. echo “sournce (http,pxesrv,)/local/” > grub.cfg fi ln -s grub2-efi-圆4/boot/efi/EFI/fedora/grub圆4.efi. ln -s shim-圆4/boot/efi/EFI/fedora/shim圆4.efi.

grub2-efi-圆4-modules/usr/lib/grub fedora cd. memtest86+/boot/memtest86+-* memtest-cur echo “ui menu.c32 ” > nf cd. Menuentry ‘Install Fedora release 29 x86_64’. Insmod gfxterm set gfxmode=auto terminal_output gfxterm set timeout=-1 Terminal_input console loadfont /12×26.pf2 Here’s what the output of my CGI looks like (I use gfxterm so IĬan load a larger font that I set up locally in the TFTP root – you should be able to just skip that line):

The kernel/initrd lines take HTTP URLs just fine, so that’s much faster.

CENTOS INSTALL TCPDUMP HOW TO

Since you already have a working BIOS PXE, I’ll assume you know how to make that config file. I’m including a script I use that sets that up (and can be re-run at any time to download the latest RPMs – this assumes the PXE server is Fedora though, but you should be able to adapt it easily enough). I put each in a subdirectory and then add symlinks to make it easier to replace things with the contents of newer RPMs. Syslinux-tftpboot shim-圆4 grub2-efi-圆4 grub2-efi-圆4-modules In my TFTP root, I then extract the following RPMs into subdirectories I’m using dnsmasq as my DHCP server, so I have this in its config (where has IP 10.10.10.2):ĭhcp-match=set:efi64,option:client-arch,7

That includes generating menus on the fly from perl CGIs (I’m old-fashioned that way :) ). I also feed most of the content out via HTTP (much faster than TFTP). I never could get SYSLINUX’s UEFI support working very well or reliably, and it didn’t support secure boot at all last I looked. I still use SYSLINUX for BIOS, but GRUB2 plus Red Hat’s secure boot shim for UEFI. I have BIOS+UEFI PXE boot set up, although it took some doing.
