As do I.  It looks like you certainly did some work.  Thank you.

At first glance, it's a very simple setup of a single system
responding to the DHCP requests and both are on a single subnet.  Once
syslinux.efi is downloaded, the only other packets are an ARP
request/response from the boot client.  DHCP packets look good too.

Looks like time to check more.
