J1
and
J2
allows
you
to
enable/disable
the
adapter's
ISA

zero-wait
state
feature.
When
enabled
(default),
the
CPU
can
transfer
data
to
the
VGA
adapter
at
the
zero-wait
state
rate
through
ISA
bus.
There
are
two
zero-wait
state
stages
that
can
be
enabled
or
disabled.
If
your
display
exhibits
pixel
drop
outs
or
the
system
hangs,
use
Jumper
J2
to
disable
the
first
zero-wait
state
stage.
If
you
still
encounter
problems,
use
Jumper
J1
to
disable
the
second
zero-wait

J8
allows
you
to
enable/disable
the

feature.
When
enabled
(default)
the
BIOS
will
determine
whether

interface,
and
will
configure

3.2.1 Monitor Support for Enhanced VGA Modes 3-3
3.3 Advanced Topics | | 3-5
The installation procedure for your VGA graphics adapter will vary
slightly depending on the type of system you have (i.e. an IBM PC/XT/
AT or compatible). Just follow the general installation instructions in
this section, and look for any special steps you will need to take for your
particular system.
3.1 Installation Procedures
To install the adapter into your system, follow these steps:
l. Turn OFF all power to your system, including any peripherals
(printer, external drives, modem, etc.).
2. Unfasten the cover mounting screws on your system. Reference
your system user manual to determine the location of the mounting
screws.
3. Remove the system cover. Reference your system user manual for
instructions on how to remove the system cover.

4. If you have an IBM PC or PC/XT: You may need to manually
configure the motherboard for the graphics card type. Reference your
system user manual for instructions on how to configure the system.
If you have an IBM AT or compatible system: You don't need to
reset any DIP switches in your system, since AT computers and
compatible systems use the SETUP file instead of DIP switches to tell
the computer what equipment is stored in your system. Just continue
on to Step 5.
5. Select an open expansion slot. Select an appropriate expansion slot
for the adapter. Any available 8-bit slot ina PC/XT/AT or compat:
ible, or 16-bit slot in a PC/AT or compatible will do. If you install
in a 8-bit slot, please set up the jumpers according to Figure 5-B.
Remove the retaining screw that holds the slot cover in place. Slide the
slot cover out and put the screw aside (you will need it to secure the
adapter).
6. Install the adapter. To install the adapter in the selected expansion
slot, place the gold-fingered edge-connector of the adapter directly
above an expansion slot on the motherboard. Gently push theVGA
adapter down until it snaps into place. Make sure it is securely seated
in the expansion slot.
7. Attach the adapter. Use the screw you removed from the expansion
slot in Step 5 to secure the adapter in place.
8. Replacethecomputer's cover. Secure the cover with the mount-ing
screws you removed in Step 2.
You have now completed the installation of your new graphics adapter on
your system. Before you use the system, however, please refer to Section
3.2, Connecting the Monitor.

3.2 Connecting the Monitor
The adapter offers a 15-pin analog connector. When you connect your
monitor to the adapter, be sure you have the right cable and cable connector.
Fixed-frequency analog monitors come equipped with a 15-pin connector.
Variable frequency analog or analog/digital monitors will require a 9-to-
15-pin cable connector.
3.2.1 Monitor Support for Enhanced VGA Modes
Your monitor must be capable of displaying the mode you choose. Table
l lists all available VGA display modes for the adapter, the monitors which
support them, plus other information that may be useful.

Note: You may need to adjust your multi-frequency monitor to display
these modes properly. Use the horizontal and vertical size and position
controls on your monitor to display without distortion.

3.3 Advanced Topics
The VGA card supports a variety of video modes (standard VGA and hi-
resolution) which are accessible through a video BIOS call from assembly
language or other higher-level programming languages. Reference Appen- ^—
dix C for sources of programming assistance.
When you start up in DOS, the screen display defaults to the standard 80
column text or alpha-numeric. mode. This is mode 3‘ on a color system, or
mode 7^ on a monochrome VGA system (see footnote references inTable
Notes section above).
