I would like to thank L. Piacenza, Jim Erickson (Zeos tech support!),
Ray Mendonsa, and Dave Angus for e-mailing me their suggestions.  The
correct answer is that THE BOARD NEEDED SOME RAM.  After I bought and
installed two 1Mx9 SIMMs, the board came up as far as the CMOS setup
screen (i.e., no other motherboard connections were required). After I
plugged in an AT-compatible keyboard and the 8-bit RLL disk controller
from my PC and entered "disable internal IDE drive" on the setup screen,
DOS came up!  I am impressed with the compatibility of the Zeos board.
