Processor Bus Clock Speed JP1, JP3

Pentium II processors are designed with one of two bus

clock speeds. The bus clock speed is always a fraction of

the processors internal speed. The table on page 13 will

help you determine the correct setting for your system.

Bus Clock Speed JP1 JP3

60 MHz OUT IN

66 MHz IN OUT

MB-P202

Processor Bus Frequency JP10, JP11

JP10 and JP11 matches the processor bus frequency with the

processors speed. The table below illustrates the settings.

Bus Frequency JP10 JP11

60 MHz OUT IN

66 MHz IN OUT

Processor Speed Ratio JP15, JP16, JP18, JP19

The Pentium II uses a clock multiplier to run faster than the

processor bus. The jumpers match the installed processors

speed with the motherboards defined processor speed. The

table below will help you determine the correct setting.

Page 24

System Memory

The motherboard uses DIMM memory. DIMM is available

in 64-pin or 72-pin, where the 72-pin DIMM provides error

correcting code (ECC).

There are a total of four banks available for memory

upgrades. The board supports DIMM in the following

combinations:

1M x 64/72 = 8 MB/bank 8M x 64/72 = 64 MB/bank

2M x 64/72 = 16 MB/bank 16M x 64/72 = 128 MB/bank

4M x 64/72 = 32 MB/bank 32M x 64/72 = 256 MB/bank

Installing and Removing DIMM

Read these instructions completely before installing or

removing DIMMs. The DIMM is held by plastic press-clips

on both sides of the slot.

Installing DIMM

1) Hold the DIMM so that the gold tab is pointing toward the

slot. The DIMM is keyed so that it will only snap into the

slot when positioned correctly.

2) Press one end of the DIMM until it inserts and its press-

clip snaps into place.

3) Press the other end of the DIMM until it inserts and its

press-clip snaps into place.

Removing DIMM

1) Pull both press-clips simultaneously, until the DIMM pops

up from its slot.

Direct Memory Access

The system supports seven DMA channels:

Controller 1 Controller 2

Channel 0 - Spare Channel 4 - Cascade

for Controller 1

Channel 1 - SDLC Channel 5 - Spare

Channel 2 - Diskette Channel 6 - Spare

Channel 3 - Spare Channel 7 - Spare

The first DMA controller holds channels 0 through 3. These

channels support 8-bit data transfers between 8-bit I/O

adapters and 8- or 16-bit system memory. Each channel can

transfer data in 4 KB blocks.

The second DMA controller holds channels 4 through 7.

Channel 4 cascades channels 0 through 3 to the

microprocessor. Channel 5, 6 and 7 support 16-bit data

transfers between 16-bit I/O adapters and 16-bit system

memory. These DMA channels can transfer data throughout

the 16 MB system-address space in 128 KB blocks.

Channel 5, 6 and 7 cannot transfer data on odd byte

boundaries.

Power Management

This option lets you select the type or degree of power saving

for Doze, Standby and Suspend modes. See PM Timers for a

brief description of both.

Max Saving: Maximum power savings (SL processors only).

User Defined: Set each mode individually. Select time-out

periods in PM Timers section.

Min Savings: Minimum savings. Inactivity period is 1 hour.

in each mode, except hard drive.

PM Controlby APM

If Advanced Power Management APM) isinstalled, selecting

Yes gives better power savings.

Video Off Method Determines the manner in which the

monitor is blanked.

V/H SYNC+Blank: System turns off vertical and horizontal

synchronization ports and writes blanks to the video buffer.

DPMS Support: Select this option if your monitor supports

the Display Power Management Signaling (DPMS) standard.

Use the software supplied with the video subsystem to select

video power management values.

Blank Screen: System only writes blanks to the video buffer.

MODEM Use IRQs

Names the interrupt request (IRQ) line assigned to the

modem, if any, on your system. Activity on the selected IRQ

always awakens the system.

MB-P202

Page 41

PM Timers

The following are Green PC power saving functions. They

are user-configurable only during User Defined Power

Management mode.

Doze Mode: After the selected period of inactivity, 1 minute

to 1 hour, the processor clock runs at slower speed while all

other devices continue to operate at full speed.

Standby Mode: After the selected period of inactivity, 1

minute to 1 hour, the fixed disk and video shut off while all

other devices continue to operate at full speed.

Suspend Mode: After the selected period of system inactivity,

1 minute to 1 hour, all devices except the processor shut off.

HDD Power Down: After the selected period of drive

inactivity, 1 to 15 minutes, the hard disk drive powers down

while all other devices remain active.

Wake Up Events

You can turn on or off monitoring of four commonly used

interrupt requests so they do not awaken the system from, or

reset activity timers for Doze and Standby modes.

For example, if you have a modem on IRQ3, you can turn on

IRQ3 as a wake-up event, so that an interrupt from the

modem can wake up the system.

Or you may want to turn off IRQ12, the PS/2 mouse, as a

wake-up event, so accidently brushing the mouse does not

awaken the system. The default wake-up event is keyboard

activity.

32 MB-P202

Page 42

Power Down and Resume Events

You can disable monitoring of common IRQs so they do not

awaken the system from, or reset activity timers for Suspend

mode.
