Thanks for testing that.  I'd like to examine this NIC further: could you let 
me know the make and model so I can buy one for myself?

Fantastic.  :)

You can't do this directly.  iPXE doesn't contain native drivers for your USB-
NIC; it is relying on the PXE support provided by the USB-NIC manufacturer.

You should, however, be able to transfer the contents of the FDD to a USB key 
and then boot from the USB key.  This should speed up the loading time.
