This drove me nuts, I tried DL and HBDL both gave me numerous different
error messages. I finally told win95 to shutdown and restart in MSDOS
mode. Then using the DL program, everything now works correctly. It is
quite a rush to finally see the Interactive C banner on the LCD panel. The
4 motor LEDs which I reported as being lit went out after the 6811 was
configured. The board appears to be functioning correctly. Hope this
helps...
