Switch 2 (parallel port)
Switch 2 tells the computer how to access the built-in parallel
port, as follows:
The built-in parallel port functions as either the primary or
secondary parallel port. You may decide to install an
option card that has its own parallel port. Make sure you
set the DIP switch or jumper on the option card as well as
the DIP switch on the Apex so that there is no conflict
between the built-in parallel port and the added card.
If you install an option card that has only a parallel port,
you must set the DIP switches to designate this as the
secondary port and leave the built-in port as the primary
port.
MS-DOS needs to know the number of parallel ports you
have. If MS-DOS searches the system for a parallel port
and finds only one, it names it LPTl:. If it finds two
parallel ports, it names the primary port LPTl: and the
secondary port LPT2:.
Switches 3 and 4 (monitor and adapter type)
These switches define the type of video card and monitor you
are using and help the system address the adapter memory
correctly. The factory setting is 80x25 color for a CGA color
graphics monitor. If you are using a monochrome monitor, set
the DIP switch for 80x25 mono. If you are using an EGA or
VGA monitor, set the DIP switches for special settings. If you
install a different video card, follow the instructions included
with your card.
