this optimized schedule, ensures that the processor’s superscalar execution units
remain busy, boosting overall performance
Dual Independent Bus (DIB)
The Pentium® III processor supports the high-performance Dual Independent Bus (DIB)
architecture. The DIB architecture places the level 2 cache on a dedicated, high-speed
cache bus allowing for the system bus to be freed up from cache traffic. This provides
significantly higher overall system bandwidth and allows for a dramatic improvement in
system performance and scalability.
Non-Blocking Level 1 Cache
The Pentium® III processor includes two separate 16 KB level 1 (L1) caches, one for
instruction and one for data. The L1 cache provides fast access to the recently used data,
increasing the overall performance of the system.

core that is completely scaleable with the processor core frequency. Features of the ATC
include:
•Non-Blocking, full speed, on-die level 2 cache
•8-way set associativity
•256-bit data bus to the level 2 cache
•Reduced latency interface to cache data (as compared to discrete caches)

Chapter 1 Hardware Features 11
Real-Time Clock, CMOS SRAM, and Battery
The real-time clock is compatible with DS1287 and MCI146818 components. The clock
provides a time-of-day clock and a multicentury calendar with alarm features and century
rollover. The real-time clock supports 256 bytes of battery-backed CMOS SRAM in two
banks that are reserved for BIOS use.
A coin-cell battery powers the real-time clock and CMOS memory. When the computer
is not plugged into a wall socket, the battery has an estimated life of three years. When
the computer is plugged-in, the 3.3 V standby current from the power supply extends the
life of the battery. The clock is accurate to ±13 minutes/year at 25°C with 3.3 VSB
applied.
The time, date, and CMOS values can be specified in the BIOS Setup program. The
CMOS values can be returned to their defaults by using the BIOS Setup program.
Note: If the battery and AC power fail, standard defaults, not custom defaults, will be
loaded into CMOS RAM at power on.
Onboard I/O
The SMSC LPC47B27X I/O controller provides the following features:
•low pin count (LPC) interface
•two 9-pin serial bus connectors, one for RS232 and one for RS422

no room for a shrouded connector.

Chapter 1 Hardware Features 13
Hardware Monitoring Components
The hardware monitor component provides low-cost instrumentation capabilities. The
features of the component include:
•internal ambient temperature sensing
•remote thermal diode sensing for direct monitoring of processor temperature
•power supply monitoring (+12, +5, +3.3, +2.5, VCCP) to detect levels above or
below acceptable values
•I2C interface with IPMB connector
LAN Subsystem
The Intel® 82559 Fast Ethernet PCI LAN subsystem provides both 10Base-T and
100Base-TX connectivity. Features Include:
•32-bit, 33 MHz direct bus mastering on the PCI bus
•10Base-T and 100Base-TX capability using a single RJ-45 connector with
connection and activity status LEDs
•IEEE 802.3u Auto-Negotiation for the fastest available connection
•Jumperless configuration; the LAN subsystem is completely software-configurable
Intel® 82559 PCI LAN Controller
The Intel® 82559 PCI LAN controller’s features include:
•CSMA/CD Protocol Engine
•PCI bus interface
•DMA engine for movement of commands, status, and network data across the PCI
bus
•Integrated physical layer interface, including:
•complete functionality necessary for the 10Base-T and 100Base-TX network
interfaces; when in 10 Mbit/sec mode, the interface drives the cable directly
•a complete set of Media Independent Interface (MII) management registers for
control and status reporting
•IEEE 802.3u Auto-Negotiation for automatically establishing the best operating
mode when connected to other 10Base-T or 100Base-TX devices, whether half-
or full-duplex capable
•Integrated power management features, including support for wake on network
event (from ACPI S3 state using the PCI bus PME# signal)
LAN Subsystem Software
The Intel® 82559 Fast Ethernet WfM PCI LAN software and drivers are available from
Intel®’s World Wide Web site. Their site address is located at:

RJ-45 LAN Connector LEDs
Two LEDs are built into each of the RJ-45 LAN connectors. The table and diagram
below describe the LED status when the StorTrends 1312 is powered up and the LAN
subsystem is operating.

Power Management Features
Power management is implemented at several levels, including:
•Advanced Configuration and Power Interface (ACPI)
•hardware support
•power connector using power button
•wake on network event
ACPI
If the motherboard is used with an ACPI-aware operating system, the BIOS can provide
ACPI support. ACPI gives the operating system direct control over the power
management and Plug and Play functions of a computer. The use of ACPI with this
motherboard requires the support of an operating system that provides full ACPI
functionality. ACPI features include:
•Plug and Play (including bus and device enumeration)
•Power management control of individual devices, add-in boards (some add-in boards
may require an ACPI-aware driver), video displays, and hard disk drives.
•methods for achieving less than 30-watt system operation in the Power On Suspend
sleeping state, and less than 5-watt system operation in the Suspend to RAM
sleeping state
•a Soft-off feature that enables the operating system to power off the computer
•support for multiple wake events (see Wake Up Devices and Events section on page
15)
•support for a front panel power and sleep mode switch
