Interference StatementInterference Statement
Note:
This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15 of FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more
of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
4. Consult the dealer or an experienced radio/television technician for
help.
Notice 1:
The changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the
equipment.
Notice 2:
Shielded interface cables, if any, must be used in order to comply with
the emission limits.

SCSI/VGA Combo Card
Features
The combo card includes external video (CN6) and 68-pin Wide SCSI
interface (CN4).
The SCSI controller chipset (AIC-7880P) is a completely integrated,
single chip SCSI host adapter for motherboard applications. Ultra speed
SCSI technology maximizes transfer speed of up to 40MB/s in high
performance workstations and servers for greatest utilization of the 133
MB/s PCI local bus.
The ATI 3D Rage Pro VGA controller chipset is a highly integrated 64
bit graphics accelerator with support for 3D and motion video like
MPEG-2. It also incorporates comprehensive support for Intel's
Accelerated Graphics Port (AGP) including 66 or 133 MHz fully
pipelined operation with sidebands.

Card Installation
Follow these steps to install the SCSI/VGA combo card.
1. Remove a bracket cover opposite an empty PCI slot.
2. Position the card over the PCI slot, then insert the card golden
fingers into the slot until the card fits in place.
3. Secure the card with a screw.
4. Connect the LED cable to the system board’s SCSI LED connector
(please refer to the system board user’s manual for the location of
this connector) and then to the LED connector (CN5) on the combo
card.

SCSI/VGA Combo Card 9
SCSI Feature
The system board features a single-chip SCSI host adapter that adds
SCSI I/O capability to the system. The chipset consists of an onboard
microcontroller, bus master interface controller, and SCSI controllers. A
50-pin Fast SCSI-II interface with 10 MB/s transfer rate and a 68-pin
Wide SCSI interface that transfers at 20 MB/s (Wide SCSI) and
40 MB/s (Ultra SCSI) are also onboard to accommodate various SCSI
devices.
Using the SCSI Feature
Follow these steps to use the SCSI feature:
1. Install a SCSI device in the system and connect it to the SCSI
interface on the system board. Please refer to the system board’s
user’s manual for the location of the SCSI interface.
2. Enter the BIOS utility to set the corresponding SCSI parameters.
3. Enter the SCSI Configuration Utility and make the necessary
changes.
For more information about the installation procedures under different
operating systems, read the README.XXX in the subdirectory of the
target operating system.

Video Function
The video controller is capable of supporting 3D video applications and
enhancing the video display at the same time. The board may come
with either 2-MB or 4-MB video memory. Larger video memory allows
you to display higher resolutions and more colors.
Supported Video Resolutions
The following table lists the video resolutions supported by the VGA
controller:
