working with niche hardware #1750

Thank you for the quick response. I do appreciate the assistance. I will try to define my issue better ...
What i am doing: I'm trying to get ipxe working on Pacstar 451 NG servers (https://defense-solutions.curtisswright.com/resources/pacstar-451-nr-data-sheet).
What i expect to happen: I'm able to successfully boot and cfg the earlier PS451 servers (https://defense-solutions.curtisswright.com/products/networking-communications/pacstar/comms-hardware/servers/pacstar-451). The same ipxe setup/cfg does not work with newer model hardware. I (guess I) expected the same h/w vendor to work with the same ipxe cfg/setup.
What is actually happening: (sorry, guess I missed explaining this part) ... The Pacstar 451 NR server never picks up the dhcp offer (is my guess), b/c it just times out. The earlier server (which works as expected) picks up the dhcp offer, I'm able to send the snponly.efi boot loader (following vmware/broadcom documentation) and load the ipxe menu and select the option and continue to boot the selected item. The Pacstar 451NR just times out and returns to the setup/bios ...

I may need to doublecheck the 1Gbe NICs -- I guess I assumed they were the same on the servers (they may not be). The 451NRs also have 10GbE NICs. Ideally I would like to leverage them if I can (they are trunked, and I was trying to leverage those commands in my autoexec.ipxe file) , but wanted to at least be able to leverage the 1Gbe NIC (which is on an access port on switch). I will add the autoexec.ipxe file to this thread (as well as the rest of my dhcp/dns/ipxe cfg (for completeness and clarity) ...
