Yes, it looks like I'm out of luck and need to find a newer machine to test this with. Moving the tftp server works to an extent - server boots right into a grub prompt.
Weird. I have a couple of Intel-based systems that do UEFI PXE boot okay, but they're much newer than the 11th gen PowerEdge (I have some of those still in service but they're not running UEFI mode). Also, they're client-type systems, not servers (a Thinkpad notebook and an Intel NUC), so possibly different firmware base.
I vaguely remember in the distant past having some kind of problem like this, and I think on those systems, I used a boot floppy (yes, that long ago!) with gPXE on it.
Not too happy to revive this old thread ...
Has anyone managed to UEFI/PXE boot CentOS6? I managed to find newer hw and have this working perfectly with CentOS7. With 6, however, I again cannot boot beyond a grub prompt.
CentOS7 bootx64.efi does not work for CentOS6 as it complains "kernel too old". Booting with CentOS6 /boot/efi/EFI/redhat/grub.efi, and the older style pxe config file as per https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/htm... results in a grub (legacy) prompt on the target machine.
