Vladimir, this indicates lpxelinux.0 couldn't talk properly with your UNDI
and there have been numerous fixes to related code.

Start with the precompiled 6.03-pre11 binaries. If that doesn't work,
you'll need a real serial port (not a USB to serial adapter; I know I can
get this on my laptop via an advanced port replicator or legacy port
extender) or to be able to load debug.c32 and its dependencies over TFTP.
