Motherboard Description SY-6BA+ IV
1-7 MICROPROCESSOR
The motherboard supports a single Slot 1 processor. The processor’s VID
pins automatically program the voltage regulator on the motherboard to
the required processor voltage. In addition, the front side bus speed (66
MHz and 100 MHz) is automatically selected. The motherboard supports
all current Slot 1 processor speeds, voltages, and bus frequencies.
1-7.1 Microprocessor Packaging
The processor is packaged in a Single Edge Contact Cartridge (SECC or
SECC2) or Single Edge Processor Package (S.E.P.P). The cartridge
includes the processor core, second-level cache subsystem, thermal plate,
and back cover.
The processor connects to the motherboard through the Slot1 connector, a
242-pin edge connector. When mounted in Slot1, the processor is secured
by a retention mechanism attached to the motherboard. A passive heatsink
is stabilized by the heatsink supports.
1-7.2 Second Level Cache
The second-level cache is located on the substrate of the CPU package.
The cache includes 0KB/128KB (Celeron) or 512 KB (PII/PIII) of
synchronous pipelined burst static RAM. All supported onboard memory
can be cached.
1-7.3 Microprocessor Upgrades
The motherboard can be upgraded with Slot 1 processors that run at higher
speeds. When upgrading the processor, use the BIOS configuration mode
to change the processor speed.
1-8 MEMORY
1-8.1 Main Memory
The motherboard has four DIMM sockets. SDRAM can be installed in one,
9
Motherboard Description SY-6BA+ IV
two, three, or four sockets. Using the serial presence detect (SPD) data
structure, programmed into an E²PROM on the DIMM, the BIOS can
determine the SDRAM’s size and speed. Minimum DIMM memory size is
8 MB; maximum DIMM memory size is 256MB. Memory size and speed
can vary between sockets.
The motherboard supports the following memory features:
l 168-pin DIMMs with gold-plated contacts
l 66/100/133 MHz SDRAM
l Non-ECC (64-bit) and ECC (72-bit) memory
l 3.3V memory only
l Supports 8/16/32/64/128/256 MB DIMM Modules
l Support unbuffered or registered single- or double-sided DIMMs
¿
Note
Slot 1 processors with 100 MHz front-side bus should be paired only with
100 MHz SDRAM. Processors with 66 MHz front side bus can be paired
with either 66 MHz or 100 MHz SDRAM.
1-8.2 SDRAM
SDRAM improves memory performance through memory access that is
synchronous with the front-side bus clock. Burst transfer rates at x-1-1-1
timing can be achieved using SDRAM, while asynchronous memory
subsystem are typically limited at x-2-2-2 transfer rates.
¿
Note
All memory components and DIMMs used with the SY-6BA+ IV
motherboard must comply with the PC SDRAM specifications. These
include: the PC SDRAM Specification (memory component specific), the
PC Unbuffered DIMM Specification, and the PC Serial Presence Detect
Specification.

Motherboard Description SY-6BA+ IV
1-8.3 ECC Memory
ECC memory detects multiple-bit errors and corrects single-bit errors.
When ECC memory is installed, the BIOS supports both ECC and nonECC mode. ECC mode is enabled in the Setup program. The BIOS
automatically detects if ECC memory is installed and provides the Setup
option for selecting ECC mode. If any non-ECC memory is installed, the
Setup option for ECC configuration does not appear and ECC operation is
not available.
1-9 CHIPSET
The Intel 440BX PCIset includes a Host-PCI bridge integrated with both
an optimized DRM controller and an A.G.P. interface. The I/O subsystem

¿
Note
Computer systems that have an unshielded cable attached to a USB port
may not meet FCC Class B requirements, even if no device or a low-speed
USB device is attached to the cable. Use shielded cable that meets the
requirements for a full-speed USB device.
14
Motherboard Description SY-6BA+ IV
1-9.5 IDE Support
The motherboard has two independent ATA 33 and two independent ATA
66 bus-mastering PCI IDE interfaces. These interfaces support PIO Mode3,
PIO Mode 4, ATAPI devices (e.g., CD-ROM), and Ultra DMA/33 (IDE1,
IDE2) or Ultra DMA/66 (IDE3, IDE4) synchronous-DMA mode transfers.
See “IDE Device installation” (on page 29) for more information. The
BIOS supports logical block addressing (LBA) and extended cylinder head
sector (ECHS) translation modes. The BIOS automatically detects the IDE
device transfer rate and translation mode.
Programmed I/O operations usually require a substantial amount of
processor bandwidth. However, in multitasking operating systems, the
bandwidth freed by bus mastering IDE can be devoted to other tasks while
disk transfers are occurring.
The motherboard also supports laser servo (LS-120) drives. LS-120
technology allows the user to perform read/write operations to LS-120
(120MB) and conventional 1.44MB and 720KB diskettes. An optical
servo system is used to precisely position a dual-gap head to access the
diskett’s 2,490 tracks per inch (tpi) containing up to 120 MB of data
storage. A conventional diskette uses 135 tpi for 1.44 MB of data storage.
LS-120 drivers are ATAPI-compatible and connect to the motherboard’s
IDE interface. (LS-120 drives are also available with SCJSI and parallel
port interfaces.) Some versions of Windows 95 and Windows NT
operating systems recognize the LS-120 drive as a bootable device in both
120 MB and 1.44 MB mode.
Connection of an LS-120 drive and a standard 3.5-inch diskette drive is
allowed. The LS-120 drive can be configured as a boot device if selected
as Drive A in the BIOS setup program.
¿
Note
If you connect at LS-120 drive to an IDE connector and configure it as
the :boot: drive and configure a standard 3.5-inch diskette drive as a “B”
drive, the standard diskette drive is not seen by the operating system.
When the LS-120 drive is configured as the “boot: device, the system will
15
Motherboard Description SY-6BA+ IV
recognize it as both the A and B drive
1-9.6 Real-Time Clock, CMOS SRAM, and Battery
The real-time clock is compatible with DS1287 and MC146818
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.
The time, date, and CMOS values can be specified in the Setup program.
The CMOS values can be returned to their defaults by using the Setup
program.
1-10 I/O INTERFACE CONTROLLER
The motherboard uses the ITE 8671 super I/O controller which features:
l Single diskette drive interface

16
Motherboard Description SY-6BA+ IV
l Bi-directional (PS/2 compatible)
l Bi-directional EPP. A driver from the peripheral manufacturer is
required for operation.
l Bi-directional high-speed ECP
1-10.3 Diskette Drive Controller
The I/O controller is software compatible with the 82077 diskette drive
controller and supports both PC-AT and PS/2 modes. In the Setup program,
the diskette drive interface can be configured for the following diskette
drive capacities and sizes.
l 360 KB, 5.25-inch
l 1.2 MB, 5.25-inch
l 720 KB, 3.5-inch
l 1.2 MB. 3.5-inch (driver required)
l 1.25-1.44 MB, 3.5-inch
l 2.88 MB, 3.5-inch
1-10.4 Keyboard and Mouse Interface
The +5 V lines to keyboard and mouse connectors are protected with a
fuse that prevents motherboard components from being damaged when an
over-current condition occurs.
The keyboard controller contains code, which provides the traditional
keyboard and mouse control functions, and also supports Power On/Reset
password protection. Power On/Reset password can be specified in the
BIOS Setup program.
The keyboard controller also supports the hot-key sequence
<Ctrl><Alt><Del>, software reset. This key sequence resets the
computer’s software by jumping to the beginning of the BIOS code and
running the Power On Self Test (POST).
1-10.5 Infrared Support
The IR connection can be used to transfer files to or from portable devices
like laptops, PDAs, and printers.
17
Motherboard Description SY-6BA+ IV
1-11 HARDWARE MONITOR
The optional hardware monitor subsystem provides low-cost
instrumentation capabilities. The features of the hardware monitor
subsystem include:
Ø An integrated ambient temperature sensor
Ø Fan speed sensors, which monitor the fan 1 and fan 2 connectors
Ø Power supply voltage monitoring to detect levels above or below
acceptable values
When suggested ratings for temperature, fan speed, or voltage are
exceeded, an interrupt is activated. The hardware monitor component
connects to the SMBus.
1-12 WAKE ON LAN TECHNOLOGY
Wake on LAN technology enables remote wakeup of the computer
through a network. Wake on LAN technology requires a PCI add-in
network interface card (NIC) with remote wakeup capabilities. The remote
wakeup connector on the NIC must be connected to the onboard Wake on
LAN technology connector. The NIC monitors network traffic at the MII
interface; upon detecting a Magic Packet, the NIC asserts a wakeup signal
that powers up the computer. To access this feature uses the Wake on LAN
technology connector.
*
CAUTION
