2-2 Jumper Settings
You can adaptthe VGA adapterfor specialhardware configurationsusing
the given jumpers on the card.
2-2.1 Select Scan Rate: Jumper J2
J2allows you to configure the scan rates of extended VGA modes to be
compatiblewith your multiscanningmonitor. J2 is operationalfor the 4
DRAM (512K)configurationonly. Ifyour monitorcan scan at 48.7KHz
or higher, remove the Jumper pin across J2. 12 in the open position will
allow noninterlaceddisplay for 1024 x768-16, and higher horizontal and
vertical scan rates for 800 x600-16. If your monitor cannot scan at
48.7KHz,leaveJumper J2 in the defaultposition.This will give interlaced
display for 10Mx768-16 and reduced horizontal and vertical scan rates

The installation procedure for your VGA graphics adapter will vary
slightly dependingon thetype ofsystem 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. If you have an olderrnodel PC, XT, or compatible,
please read Appendix Bbefore you install your graphics adapter.
3-1 Installation Procedures
To install the adapter into your system, follow these steps:
1. Turn OFFall powerto your system, including any peripherals(printer,
external drives, modem, etc.).
2. Unfasten thecover mountingscrews on your system. For older IBM PCs,
there are two cover mounting screws. However, the newer IBM XTs and
compatibles use four screws, and newer ATs use five mounting screws. All
cover mounting screws are located on the back of the computer.
3. Remove the system cover. After all cover mounting screws are ofi,
carefully slide the system unit cover forward. When the cover will not go
any further, tilt it up and lift it away.
3-1

If you have an IBM PC or PC/XT: IBM PC and PC/XT motherboards use
aDIP switch to identify the type of video display adapter installed in the
system. If you are installing the adapter in an IBM PC, XT, or compatible
system, you will need to reset positions 5and 6ofDIP switch block SW1
on your computer’smotherboard.Use Figure 4to locate switch SW1. Reset
positions5and 6 ofSW1 to the ON position.(Ifyou have an XT compatible
system, refer to your system’suser manual for the correctlactation ofSW 1.)
SW1
FIGURE 4. With aballpoint pen set SW1. positions5and 6, to ON.
If SW 1is aslide switch, you will need to use apen or apaper clip to push
positions5and 6into the ON position.If SW1 is arockerswitch,use the pen
or paper clip to push the rockers at positions 5and 6 dOWn for the ON
position.
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
systemsuse the SETUP file insteadofDIP switchesto tell the computerwhat
equipment is stored in your system. Just continue on to Step 5.
Select an open expansion slot. Select an appropriate expansion slot for the
adapter. Any available 8bit slot in aPC/XT or compatible, or 16bit slot in
aPC/AT or compatible will do. Remove the retaining screw that holds the
slot cover in place. Slide the slot cover out andputthe screw aside (you will
need it to secure the adapter).
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 the VGA graphic adapter
3-2

7. Attach the adapter. Use the screw you removed from the expansion slot in
Step 5to secure the adapter in place.
8. Replace the computer’s cover. Securethe coverwith the mounting 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, Connectingthe Monitor.
3-2 Connecting the Monitor
The adapter offers a15 pin analog connector. When you connect your
monitor to the adapter, be sure you have the right cable and cable
connector.Fixedfrequencyanalogmonitorscome equippedwith a15 pin
connector. Variable frequency analog or analog/digital monitors will
require a9to 15 pin cable connector.
Warning: Connectingor disconnectingyour monitorwhile your system
and monitor are powered on may cause damage to your VGA adapter.
3-2.1 Monitor Support for Enhanced VGA Modes
Your monitormust be capable of displayingthe mode you choose. Table

4-1 Hardware Troubleshooting
The followingare some recommended steps to take if the VGA Graphics
Adapter will not boot or operate properly in your system:
1. Check to see if the card is fimrly seated in its bus expansion. sure it is not
making contact with any other cards in the system.
2. Be sure your monitor is properly connected to the card. Be sure your
monitor’s pin definitions match those of your IMPACT card.
3. Be sure your system’s power supply is operating properly (i.e. fan operates,
system power light comes on).
4. If you are using an IBM PC/XT or compatible, be sure switches 5and 6 of
Switch Block SW 1on your motherboard are set to ON.
5. If you are using an IBM PC/XT or compatible, check to see your system
BIOS is dated October 27, 1982or later. System BIOS Versions prior to this
date will not support the adapter card.

ConfigurationRequirementsforEMS Cards.LAN Cards,and SCSI,
ESDE. or RLL Controllers
No special hardware configuration is required for EMS Cards. LAN
Cards, and SCSI, ESDI, or RLL Controllers. The BIOS automatically
detects memory conflicts between the VGA card and other system
peripheralsand boots the VGA card accordingly.In the unlikelyevent the
BIOS auto configurationscheme does not work, configure Jumper J1for
an 8—bit interfaceand then place the card in an 8-bit slot .
4-2 Commonly Asked Questions
4-2.1 Monitors
Q.
A.
Why does the display shift or change sizes when Iswitch modes?
Some monitors lack autosizing features or just do not synchronize
properly to the video board output. In some cases. horizontal and
vertical display adjustmentsmay be necessary.
What kind of monitor do I need to display 800x600 or 1024x768
resolution?
To display 800x600 resolutionat 56Hz refresh, your monitor must
be capable of a352th horizontal scan rate (e.g., NEC 2A, 3D).
At 72Hz refresh, your monitor must be capable of a418.0le scan
rate (e.g., Sony HG 1304, NEC 4D, 5D, Seiko 1450.)
To display 1024 x768 interlaced,your monitor must be capable of
a35. 5horizontalscan rate )e.g., NEC 3D, Seiko 1430 or 1440). To
display 1024 x768 noninterlaced (60Hz), your monitor must be
capable of a48.7KHz scan rate (e.g., Sony HG 1304, NEC 4D, 5D,
Seiko 1450). For 70Hz noninterlaceddisplay,your monitor must be
capable of a56.4 KHz scan rate (e.g. NEC 5D, Mitsubishi 6915).
