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...
