Strange boot options in BIOS

[clickyclick]

Hey,

I've gone through the bios settings earlier today to fix RAM settings, basically change to XMP profile, but then I noticed two strange boot options in the bios: PXE IP4 Realtek PCIe GBE Family Controller. What are these about? Should I be concerned? https://imgur.com/a/kNb0lSi

The issue has apparently solved itself once I used load optimized defaults.

For future reference:
PXE is the pre-boot execution environment which allows computers that do not have a pre-loaded Operating System to be used in a client-server context, or for operating system booting, installation and deployment--usually under the direction of the system administrator.

This is not a setting that you would normally enable in a domestic setting; and is a boot option that you do not necessarily need.
