[Etherboot-developers] Accessing network after boot

[Chad Z. H. <Chad@Hower.org>]

I have the need to write some code that can perform some basic network 
calls after its has been loaded by gPXE/PXELinux/PXE. I know that this 
is possible, however most of the solutions I have investigated require 
my code to run in 16 bit mode or use interrupt calls. I saw a note about 
gPXE not requiring interrupts, but I'm not sure what context it was in.

My requirements are:

-My application will be running in 32 bit mode on x86. I can reserve 
space in the memory map for the the bootloader to stay. I have full 
control of the memory usage.

-I dont need HTTP, or even TCP. UDP preferred, but even a raw ethernet 
packet will suffice.

Can gPXE do this? If not does anyone have any recommendations? pxelinux 
uses interrupts to make its calls which is why I cannot use it.
