Hi,

I have a different issue with this exact same chip. realtek.kpxe works 
just fine, but my task is to migrate the existing infrastructure from 
PXE to iPXE and I intended to use undionly.kpxe for that so I do not 
have to care about different hardware. The problem is, this NIC does not 
like undionly.kpxe. It gets stuck at "iPXE initialising devices...". I 
narrowed it down to some assembler code in the function pxeparent_call 
in src/arch/i386/interface/pxeparent/pxeparent.c
If I remove this assembler code I can continue, but I figured the code 
is there for a reason and I might break other hardware - every other NIC 
I tried worked so far with that code intact.
Sadly, I have no idea what this code does and why it would stop doing 
anything. Does anyone have an idea how to proceed? I should note that I 
am chainloading from pxelinux, and that I embedded Robin's 
bootstrap-script as well as a chain of trust certificates.

Thanks,

Christian
