FCC & DOC Compliance
Federal Communications Commission Statement
This device complies with FCC Rules Part 15. Operation is subject to the following
two conditions:
• This device may not cause harmful interference, and
• This device must accept any interference received, including interference that
may cause undesired operation.
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 installa-
tion. This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with manufacturer’s 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 interfer-
ence by one or more of the following measures:
• Re-orient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment to 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.
WARNING! The use of shielded cables for connection of the monitor to the graph-
ics card is required to assure compliance with FCC regulations. Changes or modifi-
cations to this unit not expressly approved by the party responsible for compliance
could void the user’s authority to operate this equipment.
Canadian Department of Communications Statement
This digital apparatus does not exceed the Class B limits for radio noise emissions
from digital apparatus set out in the Radio Interference Regulations of the Canadian
Department of Communications.

Features of the Intel YM430TX Motherboard
The IntelYM430TX motherboard is designed for the demanding PC user who wants
many intelligent features in a small package. This motherboard has the following
features:
•Intel Chipset: Intel’s 430TX PCIset with I/O subsystems.
•Multi-Processor/Multi-Speed Support: Supports 90- to 200-MHz Intel Pen-
tium
®
processors and 166- to 233-MHz Intel Pentium
®
processors with MMX
technology.
•Versatile Memory Support: Two DIMM sockets support up to 256 MB of 8 to
128MB, 168-pin, 3.3-volt SDRAM/EDO memory modules. Four SIMM sock-
ets support up to 256 MB of 4 to 64MB, 72-pin fast page mode (FPM) or
extended data out (EDO) memory modules. SIMMs and DIMMscannot be used
at the same time.
•EasyInstallation: The BIOS supportsauto detection ofharddrives, PS/2 mouse,
and Plug and Play devices to simplify setup.
•Dual PowerSupply: Two onboard power connectors support eitherATorATX
power supplies with soft-on/off features.
•ISA and PCI Expansion Slots: Two 16-bit ISA slots, three 32-bit PCI slots,
and one shared PCI/ISA slot.
•SuperMulti-I/O: Provides two high-speed, UART-compatible serial ports; one
parallel port with EPP and ECP capabilities; and an integrated keyboard control-
ler. Supports two floppy drives of either 5.25” or 3.5” (1.44 MB or 2.88 MB)
without an external card. Supports Japanese Floppy 3 mode (3.5” disks: 1.2MB)
and LS-120 floppy drives (3.5” disks: 120MB, 1.44MB, 720K).
• Desktop Management Interface (DMI): BIOS supports DMI, allowing hard-
ware to communicate within a standard protocol. (Requires DMI-enabled com-
ponents.)
•PCI Bus Master IDE Controller: The onboard Ultra DMA/33 Bus Master
IDE controller with two connectors supports four IDE devices in two channels,
allowing IDE transfer rates up to 33MB per second, and also supports enhanced
IDE devices. This controller supports PIO Modes 3 and 4 and Bus Master IDE
DMA Mode 2. BIOS supports IDE CD-ROM or SCSI bootup.
•Level 2 Cache: 512KB pipelined burst SRAM onboard.
•PS/2 Mouse, USB Connector: Includes a cable and bracket set to mount the
connectors to an unused expansion slot on the system chassis.

2. Features
(Intel YM430TX)
Performance:
• SDRAM Optimized Performance – Synchronous dynamic random access
memory (SDRAM) increases the data transfer rate from a maximum of 264 MB
per second using EDO memory to a maximum of 528 MB per second using
SDRAMs.
• Double the IDE Transfer Speed – Intel’s 430TX PCIset improves the IDE
transfer rate by using Bus Master UltraDMA/33 IDE, which can transfer data at
rates up to 33MB per second. This new technology is compatible with existing
ATA-2 IDE specs, so there is no need to upgrade current hard drives or cables.
•ConcurrentPCI–Concurrent PCIallows multiplePCI transfersfrom PCImaster
buses to memory to CPU.
• ACPI Ready – The advanced configuration and power interface (ACPI) pro-
vides more energy-saving features for future operating systems (OS) by sup-
portingOS-directpower management (OSPM).With these features implemented
in the OS, PCs can be ready around the clock every day, yet satisfy energy-
saving standards. To fully utilize the benefits of ACPI, systems must use an
ACPI-supported OS — such as the successor to Windows 95.
Intelligence:
• Virus Write Protection – Normally, viruses can destroy data on storage media.
Some new-generation viruses can also clear BIOS data, which is usually unpro-
tected. The IntelYM430TX motherboard was designed to cooperate with BIOS,
chipset, and flash memory to disable write permission when the system’s initial-
ization stage is completed upon boot-up.
• Auto Fan Off – The CPU fan will power off automatically even in sleep mode.
This feature reduces both energy consumption and system noise, and is an im-
portant feature for silent PC systems.
• Dual-function Power Button (requiresATX powersupply) – The system can
be in one of two states, sleep or soft-off. Pressing the power button for less than
4 seconds places the system into sleep mode. Pressing the power button for
more than 4 seconds places the system into soft-off mode.
• Remote Ring On (requires ATX power supply) – This feature allows a com-
puter to be turned on remotely through a modem. With this feature enabled, any
usercan accessvitalinformation fromtheir computer fromanywhere inthe world.
• Message LED – By illuminating in different ways, chassis LEDs can provide
meaningfulinformation. For example,an LED mightblink toindicatethat thefax/
modem is transferring data or light steadily to indicate that the fax/modem is idle.
