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 user’s  
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:

J47, JP47, JP46  
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 processor’s internal speed.

JP26 and JP27 synchronize the processor bus frequency with  
the processor’s speed.

Processor Speed Ratio JP32, JP31, JP30, JP29  
The PentiumPro uses a clock multiplier to run at a  
speed faster than the processor bus.  
These jumpers match the installed processor’s speed with  
single board computer’s defined processor speed.  
When upgrading processors, you may need to adjust these  
jumpers.

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  
2M x 64/72  
4M x 64/72  
8M x 64/72  
= 8 MB/bank  
= 16 MB/bank  
= 32 MB/bank  
= 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.

Timers  
The system has three programmable timers/counters  
controlled by timer/counter chips and defined as channels 0  
through 2 as follows:  
Channel 0:  
Channel 1:  
Channel 3:  
System Timer  
Refresh Request Generator  
Tone Generation for Speaker

System Interrupts  
The processor has two controllers, supplying 16 IRQs.  
Below are assignments in decreasing priority.

Note: IRQ9, IRQ10, IRQ11, IRQ12, IRQ15, IRQ3, IRQ4,  
IRQ5 and IRQ7 can be redirected to PCI add-in boards.  
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 board’s 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 2 - Diskette  
Channel 3 - Spare  
Channel 5 - Spare  
Channel 6 - 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 system’s configuration.  
The utility described below provides a bridge to PCI slots in  
excess of the four allowed by current standards.  
When your system “boots”, it’s 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:
