TI6NF Pentium Pro Motherboard User’s Manual 5
Chapter 2 Hardware Description
2.1 Processor and VRM
The TI6NF is designed to take a Pentium Pro processor with a bus
speed of 60 and 66 MHz. Since the internal clock of the CPU can be
multiples from 2 to 4 ratio of the internal bus clock, the CPU frequency
can be 150MHz to 200MHz. The TI6NF provides an onboard Voltage
Regulator to automatically detect the voltage from 2.1 to 3.5V and
supply the necessary voltage to the CPU. The VRM (Voltage Regulator
module) socket also provides power consumption higher than 35 watts.
2.2 L2 Cache
The L2 cache is Pentium Pro built-in 256KB or 512KB.
The private L2 cache bus is not connected to Package Pins, rather its
signals are routed between the two cavities using standard package
techniques. It can be driven at the full CPU core speed .
The high performance bandwidth is used by CPU to serve all L1 cache
misses, the characteristics of a CPU-cache bus and is utilized 90-95
percent of the time.
2.3 Main Memory
The TI6NF provides three 64-bit memory banks for up to 384MB of
main memory. Each bank consists of two SIMMs, SIMM1/SIMM2,
SIMM3/SIMM4, and SIMM5/SIMM6. Burst Extended Data Output
(BEDO), Extended Data Output (EDO), and Fast Page Mode DRAM
are supported. The size of the SIMM can be 4MB, 8MB, 16MB,
32MB, and 64MB, and can be configured to support for ECC (Error
Checking and Correction) or parity.
The following are the important factors for populating the SIMM
sockets:
1. Either SIMM1/SIMM2 or SIMM3/SIMM4 or SIMM5/SIMM6
bank can be populated first.
2. Each bank should consist of the same size SIMMs
3. Each bank should consist of the same type SIMMs.
ex: SIMM1 and SIMM2 should be BEDO EDO or page mode.
4. SIMMs can be mixed by the bank.
ex: SIMM1/SIMM2 are page mode and SIMM3/SIMM4 are
EDO.
6 TI6NF Pentium Pro Motherboard User’s Manual
Chapter 2 Hardware Description
5. SIMMs can be with or without parity. If you need ECC or parity
support, you need it utilize SIMMs with parity bits.
Install memory in any or all of the banks in any combination as
follows:

Chapter 2 Hardware Description
2.4 BIOS
The BIOS on the TI6NF 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 conflict. To make a computer system
PnP, an ISA PnP standard is established and supported by new
OSes, such as Windows 95. Under Windows 95, the motherboard
BIOS must have an ISA PnP extension to support the 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 APM 1.2
specifications.
2.5 I/O Port Address Map
Each peripheral device in the system is assigned a set of I/O port
address which also becomes the identity of the device. There are a total
of 1K port address space available. The following table lists the I/O
port address used on the motherboard.

Chapter 2 Hardware Description
2.6 DMA Channels
There are seven DMA channels available on the motherboard. Only
DMA2 is used by the floppy controller. In the case that ECP mode on
parallel port is used, DMA1 or DMA3 will be used.
2.7 Interrupt Request (IRQ)
There are 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
IRQ10 Reserved
IRQ11 Reserved
IRQ12 Reserved
IRQ13 Co-Processor
IRQ14 Primary IDE
IRQ15 Secondary IDE
IRQ3 INTERRUPT
IRQ4 Serial Port #1
IRQ5 INTERRUPT
IRQ6 Floppy Disk Controller
IRQ7 Parallel Port #1
2.8 Onboard PCI-IDE
The PCI IDE controller is a part of the 82440FX PCIset. It supports
PIO mode 3/4 and bus mastering. The peak transfer rate of PIO mode
3/4 can be as high as 17MB/sec. Using HDDs that support bus
mastering, the peak transfer rate can reach 22MB/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 2 Hardware Description
2.9 Onboard Multi-I/O
The onboard multi-I/O chip, SMC37C66X, provides two serial ports,
one parallel port, and one floppy controller. The serial ports are 16550
UART compatible. The parallel port supports high speed EPP/ECP
mode. The floppy controller supports up to 2.88 MB format.
