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, 100 MHz and 133 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 (S.E.C.C)
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-6VBA 133
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 256/512 MB. 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 8/16/32/64/128/256/512* MB DIMM Modules
(*512MB DIMM1,2 only)
l Support unbuffered 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-6VBA133
motherboard must comply with the PC SDRAM specifications. These
include: the PC SDRAM Specification (memory component specific), the
PC Unbuffered DIMD Specification, and the PC Serial Presence Detect
Specification.
Motherboard Description SY-6VBA 133

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 Apollo Pro 133 is a high performance, cost-effective and energy
efficient chip set for the implementation of AGP/PCI/ISA desktop
personal computer systems from 66MHz, 100MHz and 133MHz based on
64-bit Slot 1 super-scalar processors.
The Apollo Pro133 chip set consists of the VT82C693A system controller
(492 pin BGA) and the VT82C596B PCI to ISA bridge (324 pin BGA).
The system controller provides superior performance between the CPU,
DRAM, AGP bus, and PCI bus with pipelined, burst, and concurrent
operation.
The VT82C693A supports eight banks of DRAMs up to 1.5GB. The
DRAM controller supports standard Fast Page Mode (FPM) DRAM,
EDO-DRAM, Synchronous DRAM (SDRAM) and Virtual Channel
SDRAM (VC SDRAM), in a flexible mix / match manner. The
Synchronous DRAM interface allows zero wait state bursting between the
DRAM and the data buffers at 66/100/133 MHz. The eight banks of
DRAM can be composed of an arbitrary mixture of
1M/2M/4M/8M/16M/32MxN DRAMs. The DRAM controller also
supports optional ECC (single-bit error correction and multi-bit detection)
or EC (error checking) capability separately selectable on a bank-by-bank
basis. The DRAM controller can run at either the host CPU bus frequency
(66/100/133 MHz) or at the AGP bus frequency (66 MHz) with built-in
PLL timing control.
Motherboard Description SY-6VBA 133
12
The VT82C6893A system controller also supports full AGP v1.0
capability for maximum bus utilization including 2x mode transfers, SBA
(Side Band Addressing), Flush/Fence commands, and pipelined grants. An
eight level request queue plus a four level post-write request queue with
thirty-two and sixteen quad words of read and write data FIFO’ s
respectively are included for deep pipelined and split AGP transactions. A
single-level GART TLB with 16 full associative entries and flexible
CPU/AGP/PCI remapping control is also provided for operation under
protected mode operating environments. Both Window 95 VxD and
Windows 98 /NT5.0 mini port drivers are supported for interoperability
with major AGP-based 3D and DVD- capable multimedia accelerators.
The VT82C693A supports two 32-bit 3.3/5V system buses (one AGP and
one PCI) that are synchronous/ pseudo-synchronous to the CPU bus. The
chip also contains a built-in bus-to-bus bridge to allow simultaneous
concurrent operations on each bus. Five levels (double words) of post
write buffers are included to allow for concurrent CPU and PCI operation.
For PCI master operation, forty-eight levels (double words) of post write
buffers and sixteen levels (double words) of prefetch buffers are included
for concurrent PCI bus and DRAM/cache accesses. The chip also supports
enhanced PCI bus commands such as Memory-Read-Line, Memory-Read-
Multiple and Memory-Write-Invalid commands to minimize snoop
overhead. In addition, advanced features are supported such as snoop
ahead, snoop filtering, L1 write-back forward to PCI master, and L1 write-
back merged with PCI post write buffers to minimize PCI master read
latency and DRAM utilization. Delay transaction and read caching
mechanisms are also implemented for further improvement of over all
system performance.
The 324-pinm ball Grid Array VT82C596B PCI to ISA bridge supports
four levels (double words) of line buffers, type F DMA transfers and delay
transaction to allow efficient PCI bus utilization and (PCI-2.1 compliant)
The VT82C596B also includes an integrated keyboard controller with
PS/2 mouse support, integrated DS12885 style real time clock with
Motherboard Description SY-6VBA 133

extended 256 byte CMOS RAM, integrated master mode enhanced IDE
controller with full scatter/ gather capability and extension to UltraDMA-
33/66 for 33/66 MB/sec transfer rate, integrated USB interface with root
Hub and two function ports with built-in physical layer transceivers,
Distributed DMA supports, and On Now/ ACPI compliant advanced
configuration and power management interface.
For sophisticated power management, the Apollo Pro133 provides
independent clock stop control for the CPU/SDRAM, PCI, and AGP buses
and Dynamic CKE control for powering down of the SDRAM. A separate
suspend-well plane is implemented for the SDRAM control signals for
Suspend-to-DRAM operation. Coupled with the VT82C596B south bridge
chip, a complete power conscious PC motherboard can be implemented
with no external TTLs.
The Apollo Pro133 chipset is ideal for high performance, high quality,
high energy efficient and high integration desktop and notebook AGP /
PCI / ISA computer systems.

¿
Note
The mouse and keyboard can be plugged into either PS/2 connector.
Power to the computer should be turned off before a keyboard or mouse is
connected or disconnected.
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
On the front panel I/O connector, there are six pins that support Hewlett
Packard HSDL-1000 compatible infrared (IR) transmitters and receivers.
In the Setup program, Serial Port B can be direct4d to a connected IR
device. (In this case, the Serial Port B connector on the back panel cannot
be used.) The IR connection can be used to transfer files to or from
portable devices like laptops, PDAs, and printers. The Infrared Data
Association (IrDA) specification supports data transfers of 115Kbits/sec at
a distance of 1 meter.

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 connector.
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
For Wake on LAN, the 5-V standby line for the power supply must be
capable of delivering +5V ±5 % at 720 mA. Failure to provide adequate
standby current when implementing Wake on LAN can damage the power
