FCC Standards
The FCC (Federal Communications Commission) restricts
the amount of radiation and radio frequency emissions
coming from computing equipment.
Note: This equipment has been tested and found to comply
with the limits for a Class B digital device pursuant to Part
15 of the 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 radioor television reception, which can be determined by
turning the equipment off and on, the use is encouraged to try
to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and
receiver.
Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician
for help.
CSS Labs is not responsible for any radio or television
interference caused by unauthorized modifications to this
equipment. Operation with non-certified peripherals is likely
to result in interference to radio and TV reception.
iv SB-6862
To ensure compliance to FCC non-interference regulations,
peripherals attached to this device require shielded I/O cables.
NOTICE: The use of a non-shielded I/O cable with this
device is in violation of U.S. Federal law and will not allow
the device to meet the maximum emission limits.
CAUTION: Any changes or modifications not expressly
approved by the grantee of this device could void the users
authority to operate the equipment.
Note: If you have purchased the miniature tower system,
please note the following...
WARNING: The system is to be installed on desk or table
tops only. The unit will become unstable if operated as a floor
standing unit and unintentional force is applied to the top of
the unit.
Turn the unit off and unplug the power cord before you
open the cover to install any cards or peripheral devices.

Jumpers
The boards jumpers are pre-configured at the factory.
Read the following section carefully, before configuring
your system.
The board has the following jumpers:
Jumper Description
JP4 Processor bus clock speed
JP26, JP27 Processor bus frequency
JP32, JP31 Processor speed ratio
JP30, JP29
JP69, JP24 Test pins (jumper closed)
JP1, JP2, J70
J47, JP47, JP46 Test pins (jumper open)
Processor Bus Clock Speed JP4, JP3
Pentium Pro processors are designed with one of two bus
clock speeds. The bus clock speed is always a fraction of
the processors internal speed.
Bus Clock JP4 JP3
Speed
60 MHz IN OUT
66 MHz OUT IN
8 SB-6862
Processor Bus Frequency JP26, JP27
JP26 and JP27 synchronize the processor bus frequency with
the processors speed.
Processor Bus JP26 JP27
Frequency
60 MHz IN OUT
66 MHz OUT IN
Processor Speed Ratio JP32, JP31, JP30, JP29
The Pentium
Pro uses a clock multiplier to run at a
speed faster than the processor bus.
These jumpers match the installed processors speed with
single board computers defined processor speed.
When upgrading processors, you may need to adjust these
jumpers.

10 SB-6862
System Memory
There are a total of four banks available for memory
upgrades. The board supports DIMM in the following
combinations:
1M x 64/72 = 8 MB/bank
2M x 64/72 = 16 MB/bank
4M x 64/72 = 32 MB/bank
8M x 64/72 = 64 MB/bank
16M x 64/72 = 128 MB/bank
32M x 64/72 = 256 MB/bank
Installing and Removing DIMM
Read these instructions completely before installing or
removing DIMMs. The DIMM is held by plastic press-clips
on both sides of the slot.
Installing DIMM
1) Hold the DIMM so that the gold tab is pointing toward the
slot. The DIMM is keyed so that it will only snap into the
slot when positioned correctly.
2) Press one end of the DIMM until it inserts and its press-
clip snaps into place.
3) Press the other end of the DIMM until it inserts and its
press-clip snaps into place.
Removing DIMM
1) Pull both press-clips simultaneously, until the DIMM pops
up from its slot.

The PCI standard has a 4-IRQ limitation. Some PCI add-in
boards do not require IRQs. Some can share an IRQ with
another board of the same model and manufacture. Check the
add-in boards docmentation for IRQ information.
Direct Memory Access
The system supports seven DMA channels:
Controller 1 Controller 2
Channel 0 - Spare Channel 4 - Cascade
for Controller 1
Channel 1 - SDLC Channel 5 - Spare
Channel 2 - Diskette Channel 6 - Spare
Channel 3 - Spare Channel 7 - Spare
The first DMA controller holds channels 0 through 3. These
channels support 8-bit data transfers between 8-bit I/O
adapters and 8- or 16-bit system memory. Each channel can
transfer data in 4 KB blocks.
The second DMA controller holds channels 4 through 7.
Channel 4 cascades channels 0 through 3 to the
microprocessor. Channel 5, 6 and 7 support 16-bit data
transfers between 16-bit I/O adapters and 16-bit system
memory. These DMA channels can transfer data throughout
the 16 MB system-address space in 128 KB blocks.
Channel 5, 6 and 7 cannot transfer data on odd byte
boundaries.

Configuration Utilities
Overview
The BIOS Setup utility stores your systems configuration.
The utility described below provides a bridge to PCI slots in
excess of the four allowed by current standards.
When your system boots, its configuration is read into
main memory. Hard drives, floppy drives, video adapter,
memory and keyboard are described to the system.
The BIOS is pre-configured at the factory. This document is
an overview of the BIOS.
To start the program, press the <Delete> key while the
system is booting. The Utilities menu screen will display:
