3.1 Processor
The TI6NB motherboard is designed to take a Pentium II processor
running 233MHz/266MHz/300/333MHz at 66MHz CPU bus speed or
300/350/400/450MHz at 100MHz CPU bus speed with its Slot 1
processor connector.
3.2 L2 Cache
The L2 cache is integrated in the Pentium II processor. The private L2
cache bus is not connected to package pins, rather its signals are routed
between the two cavities using standard package techniques.
3.3 Main Memory
The TI6NB motherboard supports four 168-pin DIMM (Dual In-line
Memory Module) sockets to form a memory configuration from 8MB to
512MB. DIMM modules canbe 8MB, 16MB, 32MB, 64MB and 128MB
in SDRAMDRAM. Inpopulatingthe DIMM sockets, DIMM1, DIMM2,
DIMM3 and DIMM4 bank can be populated first. Refer to the following
table on how to configure the memory.
NOTE: Use SDRAM modules with PC100 specification when running
100MHz CPU bus speed. With 66MHz CPU bus speed, SDRAM modules
with PC66 or PC100 specification can be used.

3.4 BIOS
The BIOS on the TI6NB motherboard provides the standard BIOS
functions plus the following additional features:
1. ISA Plug and Play (PnP) Extension
Unlike PCI cards that are Plug and Play, ISA cards require setting
jumpers to resolve hardware conflicts. To make a computer system
PnP, an ISA PnP standard is established and supported by new
operating systems, such as Windows 95. Under Windows 95, the
motherboard BIOS must have an ISA PnP extension to support new
ISA PnP cards.
2. Power Management
The power management feature provides power savings by slowing
down the CPU clock, turning off the monitor screen and stopping the
HDD spindle motor. The BIOS fully conforms to ACPI (Advanced
Configuration and Power Interface) specification.
3.5 I/O Port Address Map
Each peripheral device in the system is assigned a set of I/O port
addresses which also becomes the identity of the device. There is a total
of 1K port address space available. The following table lists the I/O port
addresses used on the motherboard.
Address Device Description
000h - 01Fh DMA Controller #1
020h - 03Fh Interrupt Controller #1
040h - 05Fh Timer
060h - 06Fh Keyboard Controller
070h - 07Fh Real Time Clock,, NMI
080h - 09Fh DMA Page Register
0A0h - 0BFh Interrupt Controller #2
0C0h - 0DFh DMA Controller #2
0F0h Clear Math Coprocessor Busy Signal
0F1h Reset Math Coprocessor
1F0h - 1F7h IDE Interface
2F8h - 2FFh Serial Port #2(COM2)
378h - 3FFh Parallel Port #1(LPT1)
3F0h - 3F7h Floppy Disk Controller
3F8h - 3FFh Serial Port #1(COM1)

Chapter 3 Hardware Description
10 TI6NB Pentium II 440BX ATX Motherboard User’s Manual
3.6 DMA Channels
There are seven DMA channels available on the motherboard. Only
DMA2 is used by the floppycontroller. Inthe case that ECP mode on the
parallel port is utilized, DMA1 or DMA3 will be used.
3.7 Interrupt Request (IRQ) Lines
There is a total of 15 IRQ lines available on the motherboard. Peripheral
devices use an interrupt request to notify the CPU for the service
required. The following table shows the IRQ lines used by the devices on
the motherboard:
Level Function
IRQ0 System Timer Output
IRQ1 Keyboard
IRQ2 Interrupt Cascade
IRQ8 Real Time Clock
IRQ9 Software Redirected to Int 0Ah or PCI Slot Int#
IRQ10 Reserved or PCI Slot Int#
IRQ11 Reserved or PCI Slot Int#
IRQ12 PS/2 Mouse or PCI Slot Int#
IRQ13 Co-Processor
IRQ14 Primary IDE
IRQ15 Secondary IDE
IRQ3 Serial Port #2
IRQ4 Serial Port #1
IRQ5 Parallel Port #2 or PCI Slot Int#
IRQ6 Floppy Disk Controller
IRQ7 Parallel Port #1
3.8 Onboard PCI-IDE
The PCI-IDE controller is a part of the 82440BX PCIset. It supports PIO
mode 3/4 and bus mastering Ultra DMA/33. The peak transfer rate of
PIO mode 3/4 can be as high as 17MB/sec. Using HDDs that support
Ultra DMA/33, the peak transfer rate can reach 33MB/sec. There are two
IDE connectors - primary IDE and secondary IDE. With two devices per
connector, up to four IDE devices can be supported.

Chapter 3 Hardware Description
TI6NB Pentium II 440BX ATX Motherboard User’s Manual 11
3.9 Onboard Multi-I/O
The onboard multi-I/O chip, W83977TF, supports a keyboard controller
(AMIcopyright),two serial ports, one parallel port, one floppy controller
and one IrDA port. The serial ports are 16550 UART compatible. The
parallel port features high-speed EPP/ECP mode. The floppy controller
supports up to 2.88 MB format.
3.10 Onboard AGP Slot
The AGP (Accelerated Graphics Port) slot supports AGP compliant
VGA cards to achieve rich 3D and video graphics display. AGP is a
platform bus specification that enables 3D graphics capabilities including
support for z-buffering, alpha blending and faster texture mapping.
3.11 Hardware Monitoring IC
The TI6NB comes with the Winbond W83781D hardware monitoring
IC. It monitors several hardware parameters including power supply
voltages, fan speeds, and temperatures, which are very important for a
high-end computer system to work stable and properly.

CPU, S1(1) can be used to set the CPU bus speed. For 66MHz, set this
switch to ON; for 100MHz, this switch is OFF. For ‘mass produced’
CPU, S1(3) should be set to OFF for auto-detection of the CPU bus
speed.
