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,

Motherboard Description SY-6BA+100

10

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+100

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+100

11

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 non-

ECC 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

of the 440BX is based on the PIIX4E, which is a highly integrated PCI-

ISA/IDE Accelerator Bridge. This chipset consists of the Intel 82443BX

PCI/A.G.P. controller (PAC) and the Intel 82371EB PCI/ISA IDE

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.

Motherboard Description SY-6BA+100

15

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

Motherboard Description SY-6BA+100

16

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

l ISA Plug-and-Play compatible register set

l Two serial ports

l FIFO supports on both serial and diskette interfaces
