CHAPTER 4: Software Setup and Operation
The options are as follows:
• POLLING—A PC may use either
IRQ-7 or IRQ-5 for handling the
parallel port communications. If
you need to work without
interrupts (usually only with test
evaluations), delete the
semicolon in this line. This will
force the driver to operate in a
polled mode without using
hardware interrupts.
• UNIDIR—Whenever the
SETNDIS driver is loaded into
memory, it tests the parallel port
to determine whether it can be
operated in the faster
bidirectional mode. The adapter
is then configured according to
the test results. However, when
you use a long extension cable,
the bidirectional mode may not
operate reliably, even if the test
passes. In this case, you should
force the unidirectional mode by
deleting the semicolon in this
line.
• LPTn—The NDIS driver for the
Adapter is auto-configuring,
automatically detecting the
correct port to be used. To
specify the exact parallel port
with which the SETNDIS driver
is to work, delete the semicolon
in this line and specify the port
number (1 to 4) in place of the
n.
Once you have made your
changes, run the SETUP program
again, as described in Section 4.3.1.
4.4 Microsoft Windows for
Workgroups
4.4.1 I
NSTALLATION
The following procedure outlines
the installation of the SETNDIS
driver software with a new
installation of Windows for
Workgroups.
1. Start the installation of Windows
for Workgroups as described in
the “Windows for Workgroups
Installation Guide.” Follow the
procedure until you reach the
window “Network Setup.”
2. In the window “Install Network
Adapter,” insert the Network
Drivers diskette into the disk
drive. Select “Unlisted or
Updated Network Adapter” and
choose “Continue.” Enter the
appropriate path (for example,
A:\
or B:\). Then choose “OK.”
3. The “Modular Parallel Adapter”
option should display. Choose
“OK.”
4. The next window displays
Interrupt, Base I/O and Base
Memory Address settings that
should be “Automatic or
Unused.” Choose “OK.”
5. In the window “Network
Adapters,” choose “OK.”
6. Windows for Workgroups now
modifies your AUTOEXEC.BAT,
CONFIG.SYS and
PROTOCOL.INI files and
changes the extensions of the
previous versions to .00x. Choose
“OK.”
