I was able to build bin-x86_64-efi/ipxe.efi with a custom script and install it on the EFI partition. I made it the first boot option with the command: sudo efibootmgr -c -w -I \\EFI\\ipxe\ipxe.efi -L "MyTest" -d /dev/sda BootOrder: 0002,0000,0001 Boot0000* ubuntu Boot0001* Syslinux Boot0002* MyTest The custom ipxe script is as follows: #!ipxe set user-class ipxetest echo ipxe started with user-class ${user-class} clear ip4 dhcp echo Chaining to tftp://${next-server}/${filename} sleep 15 chain tftp://${next-server}/${filename} I see the echo message. So I know that my ipxe.efi is being invoked, The dhcp command does not see that link is up on net0, tries the other interfaces but is not able bring up the network. The message on the console is: Waiting for link-up on net0 see http://ipxe.org/38086193 (same message for other interfaces). Just for testing I added a retry loop on the dhcp 5 times with a 5 second delay. Same problem from either warm start or a cold boot from a powered down state. My end goal is to contact a web server on the local network that will generate the final chain command. |
