JP1, JP2, and JP3 are read by the video BIOS to select which of the six LCD flat-
panel options will be used. Connecting an unsupported LCD flat-panel will produce
unpredictable results. If the system BIOS detects that a flat panel and a VGA
monitor are both connected to the system, then the video BIOS is initialized for the
VGA monitor. The flat panel can then be turned on using the CLMODE software
described in Appendix E.
Please note that a software addressable FET switch is also provided to allow
application software control of the backlight on an LCD flat-panel. The default value
is to come up with backlight control off. For more detailed information on the LCD
flat-panels, refer to Chapter 3, Theory of Operations and Appendix D, Video Modes
and Supported Panels.
In the table below, an ‘on’ in the jumper column indicates that the connector is
jumpered. JP1, JP2, and JP3 are configured as follows to select the LCD flat-panel
type:

Due to a lack of standards in the LCD industry, standard cables are not available for
the flat panels supported on the EPC-33/34. Pinouts for the cables are listed in
Appendix D.
Mounting
The EPC-33/34 can be installed in an ISA-bus passive backplane or mounted
using mounting holes on the board.
