This article covers the inability to PXE boot on EloPOS and I-Series 2.0 devices

The EloPOS and I-Series 2.0 with Windows devices, do not have a Legacy option when it comes to booting. These systems are intended for systems which use UEFI such as Windows 10. Legacy boot is going away on most modern computers.

Typically, people want to disable UEFI when trying to install older X86 Operating Systems (Windows XP, 7 32 bit etc.) The Processors in the newer Elo units (Geminilake and Coffeelake) do not support these older systems.

Also, many PXE servers are not set up to use UEFI boot and will have errors such as PXE-E16: No offer received

If you are receiving these errors you will need to configure your PXE server to allow UEFI booting. This article from Github may be helpful: Configuring PXE Boot Servers for UEFI
