You're welcome.  Unfortunately, we can't just apply this patch as-is, since it 
would break some other configurations.

Could you build with DEBUG=undinet and tell me what is shown for the lines

  UNDINIC 0x<address> has type <type>, speed <speed>, flags <flags>
  UNDINIC 0x<address> uses IRQ <irq>

I'm most interested in the "flags" value, which is where your UNDI driver is 
supposed to indicate that it supports IRQs.  Knowing the IRQ number may also 
be relevant.

That message must be coming from NTLDR rather than iPXE.  Could you try 
building with DEBUG=int13, so we can see what is happening?
