Ok, I found the issue. The Geo IP filter on the firewall was preventing accessing the remi repository, which was keeping me from updating php. Disabled the Geo IP filter and ran a fresh install and everything is working like a charm.

Thanks again guys for the help!

Good News Everyone!!!

I was able to get ipxe.efi to work, got a new USB to Ethernet adapter. The client was able to load and run the full registration without issue.

USB Ethernet adapter that works is HP P/N829834-001, it’s a USB 3.0 to Gigabit adapter. May want to add this to the confirmed working hardware list.

Thank you @george1421 for all the help was just about to load the bootable usb when the adapters arrived.
