If you mean your ROM -> undionly.kpxe works, that's good.

Perhaps you could embed undionly.kpxe into your ROM and chain it 
automatically.

That's what a lot of folks do, which contributes to gPXE's driver set 
for the benefit of its users.

Embedding some proprietary ROM into a gPXE ROM seems a little inside-out 
to me.  Anything's possible...  gPXE would have to find your UNDI/PXE 
stacks, so you'd have to hack gPXE to look for them in your UNDI ROM 
image that you embed, plus you'd have to modify gPXE to otherwise 
completely ignore your UNDI ROM embedded image so that it is not used as 
a boot file or initrd.

Perhaps you'd like to tackle porting the driver to gPXE by studying some 
gPXE drivers?  You need not worry about the UNDI portions of your code, 
since gPXE takes care of all of that.  Just the hardware-specific 
portions will need porting.  It might make for a unique challenge for you.

Good luck!
