@noelpd said in HP 210 Netbook (RealTek NIC) - DHCP Failed on PXE Boot:
So rebuilding a custom bzImage file will not effect it at all
No it won’t
The typical flow is PXE ROM -> tftpserver -> iPXE kernel (what you see in the OP post, and why the iPXE error message) -> FOG httpserver -> bzImage + init.xz (FOS image)
The issue is for some reason iPXE can find the nic (no problem) but it can’t pick up a dhcp address. To me this still screams of being a spanning tree issue, but you have tested otherwise.
