I compiled Bochs on Linux and installed a linux
in it, but when I ping a machine on my LAN, I get
packet loss. Sometimes as much as 70% is lost.
So I read ne2k.cc, Linux 8390 driver and 8390 chip
specification. I find that 8390 command register START
bit is misused in ne2k.cc. According to the chip
specification, even if START=0, the chip does not stop
working.
