advice in that message. It is at least out dated. You do not have to <br>
change your dhcp config after each install and you can continue to use <br>
your fai-chboot config files. Syslinux does support EFI booting. It's <br>
in the syslinux-efi package.<br>
<br>
Here is the code in my dhcp config file that sets the filename option <br>
depending on EFI/BIOS boot:<br>
<br>
=== begin ===<br>
# tell a kernel how to boot via PXE or NFS<br>
server-name faiserver;<br>
next-server faiserver;<br>
# Check pxe boot code #93 to determine whether we are booting via BIOS <br>
or EFI<br>
# 2018-07-04: jheim<br>
option architecture-type code 93 = unsigned integer 16;<br>
class "pxeclients" {<br>
match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";<br>
if option architecture-type = 00:00 {<br>
filename "fai/pxelinux.0";<br>
} else {<br>
filename "fai/syslinux.efi64";<br>
}<br>
}<br>
=== end ===<br>
<br>
The file syslinux.efi64 is from the debian syslinux-efi package. It's <br>
original name/path was /usr/lib/SYSLINUX.EFI/efi64/syslinux.efi. I <br>
renamed it syslinux.efi64 to distinguish it from the 32-bit syslinux.efi <br>
file. Then I decided not to bother with 32-bit EFI boots. You also need <br>
some libs in your tftp directory to support EFI booting via syslinux. I <br>
think if you modify your dhcp config as abobe, copy the necessary files <br>
from the syslinux-efi package to your tftp space, you'll successfully <br>
boot into the FAI install. You will also need to create new disk config <br>
files to partition via gpt instead of msdos. (More on that below.)<br>
<br>
1. Cut/passte above code into your dhcp config.<br>
2. apt-get install syslinux-efi<br>
3a. cp /usr/lib/SYSLINUX.EFI/efi64/syslinux.efi /srv/tftp/fai/<br>
3b. cp /usr/lib/syslinux/modules/efi64/ldlinux.e64 /srv/tftp/fai/<br>
<br>
Done with the boot stuff. Now the disk config stuff. Code that detects <br>
whether you have booted via BIOS or EFI already exists in the fai-doc <br>
examples. It's in a class script called 60-grub. It creates either <br>
GRUB_PC or GRUB_EFI class. You have to retain your old BIOS disk config <br>
files for older machines. I used to create a class called LARGEDISK for <br>
disks large enough to partition into /, /var/ usr, ... So I just renamed <br>
that GRUB_PC. Then I copied that file to GRUB_EFI andmodified it for <br>
gpt partitioning and EFI boot. It looks like this:<br>
<br>
=== begin ===<br>
# 2018-07-04: jheim<br>
disk_config disk1 disklabel:gpt fstabkey:label align-at:1<br>
primary /boot/efi 204800K vfat rw<br>
primary /usr/local 157286400K ext4 rw,relatime <br>
createopts="-L LOCALFS"<br>
primary / 72G- ext4 rw,relatime <br>
createopts="-L ROOTFS"<br>
primary swap 8G swap rw <br>
createopts="-L SWAPFS"<br>
# EOF<br>
=== end ===<br>
<br>
<br>
<br>
<br>
<br>
