CHAPTER 2 INSTALLATION AND UPGRADE

2.1 CPU Installation

Slot 1 Processor

The Intel Pentium II Processor utilizes Single Edge Contact (S.E.C) cartridge packaging
technology. The S.E.C cartridge allows the L2 cache to remain tightly coupled to the
processor, while maintaining flexibility when implementing high performance processor into
the systems. The S.E.C cartridge utilizes surface mount core components and a substrate with
an edge finger connection. The S.E.C cartridge package (Figure 1) introduced on the Pentium
II processor will also be used in the Deschutes and future Slot 1 processors.

Figure 1. Intel Pentium II end-view.

Slot 1 Retention Mechanism and Attach Mount

The Intel enabled retention mechanism (Figure 2) holds the Slot 1 processor in place. The
retention mechanism is keyed to the Slot 1 connector to ensure proper installation. The
retention mechanism attach mount is pressed from the bottom of the motherboard and the
retention mechanism is attached with captive nuts which are part of the retention mechanism
assembly.

Figure 2. Slot 1 Mount diagram

Assembled S.E.C Cartridge, Heat Sink, Retention Mechanism.

The Pentium II processor will also be offered as an Intel Boxed processor. Intel Boxed
processor are intended for system integrators who build systems from motherboards and
standard components. The Boxed Pentium II processor will be supplied with an attached
fan/heatsink.

Hold the processor so that the fan shroud is facing toward the pegs on the motherboard. Slide
the processor into the retention mechanism and slide the supports onto the pegs. Ensure that
the pegs on the motherboard slide into the holes in the heatsink support and that the alignment
notch in the processor fits over the plug in Slot 1. Push the processor down firmly, with even
pressure on both side of the top, until it is seated. As show in (Figure 3).

Figure 3. Slot 1 Pentium II CPU

 The CPU cooling fan can improve the ventilation of the motherboard in the case. The

conduction of the airflow can enhance the cooling effect to the voltage regulator and
onboard heatsink by continuously keeping the air-stream flows.
The airflow of the fan/heatsink is into the center and out of the sides of the fan/heatsink.
The large arrows in the Figure 4 denote the direction of airflow.

Figure 4 Airflow of fan/heatsink

2.2 System Memory

The Rhino II supports 60ns, faster Fast Page Mode(FPM) or Extended Data Out (EDO)
DRAMs. It is recommended to populate Bank 1 first. Memory error checking and correction,
ECC, is supported through parity SIMMS (x36).

To install SIMMs, do the following procedure:

1. Holding the SIMM only by the edges, remove it from its antistatic

package.

2. Position the SIMM at about a 45o angle relative to the motherboard. Make sure

the small notch in the middle of the bottom edge of the SIMM aligns with the notch in
the SIMM socket.

1. Insert the bottom edge of the SIMM into the SIMM socket and make sure it is seated

firmly.

2. When the SIMM seats correctly, hold it at each end and gently push the top edge towards

the retaining clips of the connector until the SIMM snaps into place. If the SIMM does
not install correctly, gently spread the retaining clips just enough so that you can pull
away the top edge of the SIMM and try again.

Below is some of the possible configuration for Rhino II.

2.3 Keyboard Interface

PS/2* keyboard/mouse connectors are located on the back panel side of the board. It is
recommended to turn off the system power before installing or removing a keyboard or mouse.

2.4 Real Time Clock, CMOS RAM and Battery

The integrated Real Time Clock (RTC) provides a time of day clock, and 100-year calendar
with alarm features. These can be set in the BIOS SETUP program. The RTC also supports
242-byte battery-backed CMOS RAM for BIOS use. The CMOS RAM value can be cleared to
the system defaults by using a jumper on (JP13).

Chapter 3 Overview of Award Bios Setup Menu Screens

Award's ROM BIOS provides a built-in Setup program which allows user to modify the basic
system configuration and hardware parameters. The modified data will be stored in a battery
backed CMOS RAM so data will be retained even when the power is turned off. In general, the
information saved in the CMOS RAM stay unchanged unless there is configuration change in
the system, such as hard drive replacement or new equipment change.

It is possible that CMOS had a battery failure which cause data lose in CMOS_RAM. If so,
re_enter system configuration parameters become necessary.

This chapter explains the information contained in the Setup program and tell you how to
modify the setting according to your system configuration.

The BIOS supports Software Turbo Speed features. Instead of processing the Turbo Speed
Button on the front panel, simply press the <Ctrl>, <Alt>, and <+> keys at the same time to
enable the Turbo Speed feature; and press the <Ctrl>, <Alt>, and <-> keys at the same time to
disable the feature.

Moving around the BIOS and Chipset Features (refer to the next section) Setup programs
shown works the same way as moving around the Standard CMOS Setup program. User are
not encouraged to run the BIOS and Chipset Features Setup programs. Your system should
have been fine-tuned before shipping. Improper Setup may cause the system to fail, consult
your dealer before making any changes.

Virus Warning

When enabled, you receive a warning message if a program (specifically, a virus)
attempts to write to the boot sector or the partition table of the hard disk drive. You
should then run an anti-virus program. Keep in mind that this feature protects only
the boot sector, not the entire hard drive.

NOTE: Many disk diagnostic programs that access the boot sector table can trigger
the virus warning message. If you plan to run such a program, we recommend that
you first disable the virus warning.

11

CPU Internal Cache

Cache memory is additional memory that is much faster than conventional DRAM
(system memory). CPUs from 486-type on up contain internal cache memory, and
most, but not all, modern PCs have additional (external) cache memory. When the
CPU requests data, the system transfers the requested data from the main DRAM
into cache memory, for even faster access by the CPU.

CPU Level 2 Cache

The External Cache field may not appear if your system does not have external
cache memory.

Quick Power On Self Test

Select Enabled to reduce the amount of time required to run the power-on self-test
(POST). A quick POST skips certain steps. We recommend that you normally
disable quick POST. Better to find a problem during POST than lose data during
your work.

Boot Sequence

The original IBM PCs loaded the DOS operating system from drive A (floppy disk),
so IBM PC-compatible systems are designed to search for an operating system first
on drive A, and then on drive C (hard disk). However, modern computers usually
load the operating system from the hard drive, and may even load it from a CD­ROM drive.

Swap Floppy Drive

This field is effective only in systems with two floppy drives. Selecting Enabled
assigns physical drive B to logical drive A, and physical drive A to logical drive B.

Boot Up Floppy Seek

When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have
40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KB, 1.2
MB, and 1.44 MB capacity all have 80 tracks. Because very few modern PCs have
40-track floppy drives, we recommend that you set this field to Disabled to save
time.

Boot Up NumLock Status

Toggle between On or Off to control the state of the NumLock key when the system
boots. When toggled On, the numeric keypad generates numbers instead of
controlling cursor operations.

Boot Up System Speed

Select High to boot at the default CPU speed; select Low to boot at the speed of the
AT bus. Some add-in peripherals or old software (such as old games) may require a
slow CPU speed. The default setting is High.

Typematic Rate Setting

When Disabled, the following two items (Typematic Rate and Typematic Delay)
are irrelevant. Keystrokes repeat at a rate determined by the keyboard controller in
your system.

When Enabled, you can select a typematic rate and typematic delay.

Typematic Rate (Chars/Sec)

12

When the typematic rate setting is enabled, you can select a typematic rate (the rate
at which character repeats when you hold down a key) of 6, 8, 10,12, 15, 20, 24 or
30 characters per second.

Typematic Delay (Msec)

When the typematic rate setting is enabled, you can select a typematic delay (the
delay before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.

Security Option

If you have set a password, select whether the password is required every time the
System boots, or only when you enter Setup.

PCI/VGA Palette Snoop

Your BIOS Setup many not contain this field. If the field is present, leave at
Disabled.

OS Select for DRAM > 64MB

Select OS2 only if you are running OS/2 operating system with greater than 64 MB
of RAM on your system.

Shadow

Software that resides in a read-only memory (ROM) chip on a device is called
firmware. The Award BIOS permits shadowing of firmware such as the system
BIOS, video BIOS, and similar operating instructions that come with some
expansion peripherals, such as, for example, a SCSI adaptor.
Shadowing copies firmware from ROM into system RAM, where the CPU can read
it through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by
the system through the 8-bit X-bus. Shadowing improves the performance of the
system BIOS and similar ROM firmware for expansion peripherals, but it also
reduces the amount of high memory (640 KB to 1 MB) available for loading device
drivers, etc.

Enable shadowing into each section of memory separately. Many system designers
hardware shadowing of the system BIOS and eliminate a System BIOS Shadow
option.

Video BIOS Shadow

Video BIOS shadows into memory area C0000-C7FFF. The remaining areas shown
on the BIOS Features Setup screen may be occupied by other expansion card
firmware. If an expansion peripheral in your system contains ROM-based firmware,
you need to know the address range the ROM occupies to shadow it into the correct
area of RAM.

Auto Configuration

Auto Configuration selects predetermined optimal values of chipset parameters. When
Disabled, chipset parameters revert to setup information stored in CMOS. Many fields in this
screen are not available when Auto Configuration is Enabled.

DRAM Speed Selection

The value in this field must correspond to the speed of the DRAM installed in your system.
DO NOT change the default setting of this field, as determined by the system board
manufacturer for the installed DRAM. This value is access speed, so a lower value means a
faster system.

DRAM RAS# Precharge Time

The precharge time is the number of cycles it takes for the RAS to accumulate its charge
before DRAM refresh. If insufficient time is allowed, refresh may be incomplete and the
DRAM may fail to retain data.

MA Additional Wait State

Selecting Enabled inserts an additional wait state before the beginning of a memory read. The
setting of this parameter depends on the board design. Do not change from the manufacturer's
default unless you are getting memory addressing errors.

RAS# to CAS# Delay

This field lets you insert a timing delay between the CAS and RAS strobe signals, used when
DRAM is written to, read from, or refreshed. Disabled gives faster performance; and Enabled
gives more stable performance.

14

DRAM Read Burst (B/E/F)

Set the timing for burst-mode reads from DRAM. The lower the timing numbers, the faster the
system addresses memory.

DRAM Write Burst (B/E/F)

Set the timing for burst-mode writes from DRAM. The lower the timing numbers, the faster the
system addresses memory.

ISA Bus Clock

Set the speed of the ISA bus here. The settings are tied to the speed of the PCI bus. If the PCI
bus operates at 33 MHz, a setting of PCICLK/4 (default) would yield an ISA bus speed of
approximately 8 MHz, the standard speed of the ISA bus. While most devices operate at higher
ISA bus speeds, try a slower bus speed if your ISA device does not function properly at a high
bus speed.

DRAM Refresh Queue

Enabled permits queuing up to four DRAM refresh requests, so DRAM can refresh at optimal
times. Disabled makes all refreshes priority requests. Installed DRAM must support this
feature; most do.

DRAM RAS Only Refresh

An alternate to CAS-before-RAS refresh. Leave Disabled unless your DRAM requires this
older method of refresh generation.

DRAM ECC/Parity Select

Select Parity, ECC, or Disabled, depending on the type of DRAM installed in your system.

Fast DRAM Refresh

The cache DRAM controller offers two refresh modes, Normal and Hidden. In both modes,
CAS takes place before RAS but the Normal mode requires a CPU cycle for each. On the other
hand, a cycle is eliminated by "hiding" the CAS refresh in Hidden mode. Not only is the
Hidden mode faster and more efficient, but it also allows the CPU to maintain the status of the
cache even if the system goes into a power management "suspend" mode.

Read-Around-Write

DRAM optimization feature: If a memory read is addressed to a location whose latest write is
being held in a buffer before being written to memory, the read is satisfied through the buffer
contents, and the read is not sent to the DRAM.

PCI Burst Write Combine

When this option is Enabled, the chipset assembles long PCI bursts from the data held in these
buffers.

PCI-To-DRAM Pipeline

DRAM optimization feature: If Enabled, full PCI-to-DRAM write pipelining is enabled.
Buffers in the chipset store data written from the PCI bus to memory. When Disabled, PCI
writes to DRAM are limited to a single transfer per write cycle.

15

CPU-To-PCI Write Post

When this field is Enabled, writes from the CPU to the PCI bus are buffered, to compensate for
the speed differences between the CPU and the PCI bus. When Disabled, the writes are not
buffered and the CPU must wait until the write is complete before starting another write cycle.

CPU-To-PCI IDE Posting

Select Enabled to post write cycles from the CPU to the PCI IDE interface. IDE accesses are
posted in the CPU to PCI buffers, for cycle optimization.

System BIOS Cacheable

Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in
better system performance. However, if any program writes to this memory area, a system
error may result.

Video RAM Cacheable

Selecting Enabled allows caching of the video BIOS ROM at C0000h to C7FFFh, resulting in
better video performance. However, if any program writes to this memory area, a system error
may result.

8/16 Bit I/O Recovery Time

The I/O recovery mechanism adds bus clock cycles between PCI-originated I/O cycles to the
ISA bus. This delay takes place because the PCI bus is so much faster than the ISA bus.

These two fields let you add recovery time (in bus clock cycles) for 16-bit and 8-bit I/O.

Memory Hole at 15M-16M

You can reserve this area of system memory for ISA adapter ROM. When this area is reserved,
it cannot be cached. The user information of peripherals that need to use this area of system
memory usually discusses their memory requirements.

DRAM Fast Leadoff

Select Enabled to shorten the leadoff cycles and optimize performance.

This option allows you to select the type (or degree) of power saving for Doze, Standby, and Suspend modes. See the section PM Timers for a brief description of each mode.

This table describes each power management mode:

Max Saving Maximum power savings. Only Available for SL CPUs. Inactivity period is

1 minute in each mode.

User Define Set each mode individually. Select time-out periods in the PM Timers

section, following.

Min Saving Minimum power savings. Inactivity period is 1 hour in each mode.

PM Control by APM

If Advanced Power Management (APM) is installed on your system, 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 of the Video Electronics
Standards Association (VESA). Use the software supplied for your video
subsystem to select video power management values.

Blank Screen System only writes blanks to the video buffer.

This feature allows you to select the IRQ# to meet your modem’s IRQ#.

HDD Power Management

HDD Off After

After the selected period of drive inactivity (1 to 15 minutes), the hard disk drive powers down while all other devices remain active. Selecting Suspend tells the drive to power down immediately.

Doze Mode

After the selected period of system inactivity (1 minute to 1 hour), the CPU clock runs at slower speed while all other devices still operate at full speed.

Standby Mode

After the selected period of system inactivity (1 minute to 1 hour), the fixed disk drive and the video shut off while all other devices still operate at full speed.

Suspend Mode

After the selected period of system inactivity (1 minute to 1 hour), all devices except the fixed disk drive and CPU shut off.

PCI Masters

When Enabled, any PCI bus master activity wakes up the system or resets the inactivity timer.

Local Devices

When Enabled, any local device activity wakes up the system or resets the inactivity timer.

18

IRQn

When Enabled, any activity from the selected IRQ wakes up the system or resets the inactivity
timer. The following is a list of IRQs assigned to common system peripherals.

IRQ3 (COM 2 ) IRQ10 (Reserved)

Resources Controlled By

The Award Plug and Play BIOS can automatically configure all the boot and Plug and Play
compatible devices. If you select Auto (Manufacture default), all the interrupt request (IRQ)
and DMA assignment fields disappear, as the BIOS automatically assign them.

Reset Configuration Data

Normally, you leave this field Disabled. Select Enabled to reset Extended System
Configuration Data (ESCD) when you exit Setup if you have installed a new add-on and the
system reconfiguration has caused such a serious conflict that the operating system cannot
boot.

IRQ n Assigned to

When resources are controlled manually, assign each system interrupt as one of the following
types, depending on the type of device using the interrupt:
Legacy ISA Devices compliant with the original PC AT bus specification, requiring a specific
interrupt (such as IRQ4 for serial port 1).
PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for PCI or
ISA bus architecture.

DMA n Assigned to

When resources are controlled manually, assign each system DMA channel as one of the
following types, depending on the type of device using the interrupt:
Legacy ISA Devices compliant with the original PC AT bus specification, requiring a specific
DMA channel
PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for PCI or
ISA bus architecture.

PCI IRQ Activated by

Leave the IRQ trigger set at Level unless the PCI device assigned to the interrupt specifies Edge-triggered interrupts.

PCI IDE IRQ Map to

This field lets you select PCI IDE IRQ mapping or PC AT (ISA) interrupts. If your system
does not have one or two PCI IDE connectors on the system board, select values according to
the type of IDE interface(s) installed in your system (PCI or ISA). Standard ISA interrupts for
IDE channels are IRQ14 for primary and IRQ15 for secondary.

Primary/Secondary IDE INT#

Each PCI peripheral connection is capable of activating up to four interrupts: INT# A, INT# B,
INT# C and INT# D. By default, a PCI connection is assigned INT# A. Assigning INT# B has
no meaning unless the peripheral device requires two interrupt services rather than just one.
Because the PCI IDE interface in the chipset has two channels, it requires two interrupt
services. The primary and secondary IDE INT# fields default to values appropriate for two PCI
IDE channels, with the primary PCI IDE channel having a lower interrupt than the secondary.
