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 MB-5865
Page 5
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.

Expansion Slots
There are a total of seven expansion slots on the
motherboard. Three slots provide 16-bit wide ISA busses.
Four of the slots are PCI bus connectors. One PCI slot is
shared with an ISA connector, so that only one of them can
be used.

The SIMM is held by plastic press-clips on both sides of the
slot.
Installing SIMM
1) Hold the SIMM so that the gold tab is pointingtoward the
slot and the SIMMs notched side is on the right.
2) Gently press the SIMM into the slot.
3) Rotate the SIMM until it clicks into place.
Removing SIMM

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 64 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.

BIOS Setup is a utility that stores your computers
configuration. 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 for you at the factory. This
document provides an overview of the BIOS, which you can
use when reconfiguring your system.
The BIOS Setup Utilities program is built into the CMOS
on your system board. To start the program, press the
<Delete> key while the system is booting. The Utilities
menu screen will display:

The Security option allow you to define a password. Enable
the password option through Advanced Setup.
The Default option allows you to change all of your Setup
values to Optimal or Fail-Safe settings. Or you can return
the system to its original settings.
The most commonly used option is Standard Setup.

DRAM Refresh Rate specifies the processors internal
clock, used to refresh the DRAM.
ISA Clock Divisor is the factor used to divide the clock
signal used for the PCI bus to provide the ISA bus signal.
For a 75 MHz processor, select PCICLK/3. For all other
speeds, select PCICLK/4.
Turbo Read Lead Off when enabled, results in a 1 host
clock pull-in of all read lead off timings.
Serr # Output Type system error output signal type for
the system.
Serr # Enable enables system to report memory errors.
Memory Address Drive Strength select 8 mA or 12 mA
output for memory address signal strength.
NA Disable (NAD) for External Cache next address
disable affects system performance.
Extended Cacheability selects memory cacheable space.

Instant On Timer is a type of green mode timer lets you
wake up the system at the same time that you trigger it.
IRQ3, 4, 5, 7, 8, 9 can either be ignored or monitored.
When monitored, activity on the IRQ is used to wake the
system up.
