I was able to change the MAC address (using fconfig). I am able to do ping
from Win NT host and get back packets. I cannot run using BOOTP, I must use
a static IP address.
However, I still am not able to run the telnet application and connect to
the MBX board. Do you know what is the problem there?
Do I need to run a BOOTP server from my host?
Should I try a tftp server application?
