Summary ... generic Novell NE2000 standard (PCI and ISA versions).

I've used PPP over a real serial cross-over cable.  If NetNe2000 
refuses to work, I can try PPP.

Thanks for explaining that.  I was unclear about what is configured in 
QEMU and what in the OS.  Couldn't find it in documentation.  Will 
have another go at TAP.

Thanks again,                            ... P.
