Note on Printer Selection
Printer ports can be described in either of two ways: logical and
physical. Logical printer ports are what we would understand as a first
or second printer port, i.e., LPT1 or LPT2. A physical port is defined as
the actual hexadecimal address of the printer port, i.e., 03BCh, 0378h,
or 0278h. The system BIOS first searches for a printer port at 03BCh. If
one is not found, 0378h is checked. If a port is found at 0378h, it is
initialized as LPT1. If two ports are found, 03BCh is initialized as LPT1,
and 0378h is then initialized as LPT2.
Most monochrome video boards with a parallel printer port attached
use I/O address 03BCh. If the IDE200 controller is configured for LPT1
(0378h) and a mono-video board is present in the system, the IDE200’s
parallel port will be seen as LPT2.
