- 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.
