and INF File

but loading the INF file into sbl_02\edk2\UefiPayloadPkg\UefiPayloadPkg.dsc and sbl_02\edk2\UefiPayloadPkg\UefiPayloadPkg.fdf caused the build binary to not load.

I commented out the above entries and then modified sbl_02\edk2\UefiPayloadPkg\UefiPayloadPkg.dsc and sbl_02\edk2\UefiPayloadPkg\UefiPayloadPkg.dec

I added into the dsc the following

# Disable DHCP
gUefiPayloadPkgTokenSpaceGuid.PcdIPv4Enable|TRUE
gUefiPayloadPkgTokenSpaceGuid.PcdDhcp|FALSE

# Static IP configuration for eth0
gUefiPayloadPkgTokenSpaceGuid.PcdIp4Address0|192.168.1.5
gUefiPayloadPkgTokenSpaceGuid.PcdIp4SubnetMask0|255.255.255.0
gUefiPayloadPkgTokenSpaceGuid.PcdIp4Gateway0|192.168.1.1

This booted into UEFI shell, but didn't assign the IP address.

I will have multiple interfaces i need to set static IP addresses to, but eth0 is of course the first :-)

Any help gratefully received.

Kind regards
