I have a TFTP server setup where I copied GPXE customized iso image. When I boot a machine using PXE boot - I get "NBP is too big to fit into free base memory". GPXE iso image is around 678 KB. Please help me how use PXE boot to boot gPXE too to get support for the richer protocols.

Thanks in advance

I think, you are correct, this is an exact duplicate. – Tibor Apr 16 '12 at 23:10

I'm afraid your network hardware doesn't support boot images of that size, try to reduce your boot image or make it a two steps loader.

There's a good guide on the gPXE wiki about chanining gPXE into a 2 steps boot, have a look here
