Precaution Before Start
Static Electricity Damage:
Static electricity can easily damage your motherboard. Observing a few
basic precautions can help safeguard against damage that could result
in expensive repairs. Follow the simple measures below to protect
your equipment from static electricity damage.
1. Keep the motherboard and other system components in their anti-static packaging until
you are ready to install them.
2. Touch a grounded surface before you remove any system component from its protective
anti-static packaging. Unpacking and installation should be done on a grounded, antistatic mat. The operator should be wearing an anti-static wristband, grounded at the
same points as the anti-static mat.
3. After removing the motherboard from its original packaging, only place it on a
grounded, anti-static surface component side up. Immediately inspect the board for
damage. Due to shifting during shipping, it is suggested that the installer press down
on the entire socket ICs to ensure they are properly seated. Do this only with the board
placed on a firm flat surface.
4. During configuration and installation touch a grounded surface frequently to discharge
any static electrical charge that may have built up in your body. The best precaution is
to wear a grounded wrist strap. Avoid touching the components When handling the
motherboard or an adapter card. Handle the motherboard and adapter cards either by
the edges or by the adapter card case-mounting bracket.
Misplaced Jumper Damage:
There are critical headers used for connectors or power sources. These
are clearly marked separately from the jumpers listed in Motherboard
Layout. Incorrect setting jumpers and connectors may lead to damage
to your motherboard. Please pay special attention not to connect these
headers in wrong directions

4. BIOS Setup
44.. BBIIOOSS SSeettuup
The IN620 motherboard uses AWARD BIOS,
which is stored in a Flash EEPROM and can be
upgraded by a floppy disk-based program. The
BIOS has a built-in Setup Program that allows
users to modify the basic system configuration
settings. The settings are then stored in a
dedicated battery-backed memory, called
CMMOS RAM that retains the information when
the power is turned off.
The BIOS provides critical low-level support for the system’s central processing, memory
and I/O subsystems. The AWARD BIOS has been customized by adding important,
nonstandard, features such as virus and password protection, power management, and
detailed fine-tuning of the chipset which controls the system. The remainder of this manual
is intended to guide you through the process of configuring your system using the BIOS
Setup.
4.1 BIOS Setup
The AWARD BIOS is immediately activated when you first turn on the computer. The BIOS
reads system configuration information in CMOS RAM and begins the process of checking
the system and configuring it through the power-on self test (POST). When these
preliminaries are finished, the BIOS seek an operation system on the data storage devices
(hard drive, floppy drive, etc.). The BIOS launches the operating system and hands over
control of system operation to it.
To start Setup, press the <Del> key during boot-up before or while a message similar to this
appears briefly at the bottom of the screen during POST (Power On Self Test):
p
Press DEL if you want to enter SETUP
If the above message disappears before you have responded and you still wish to enter Setup,
reboot the system to try again by pressing the “RESET” button on the system case. You may
also restart by simultaneously pressing the <Ctrl>, <Alt> and <Delete> keys.
Press F1 to continue, DEL to enter SETUP.

4.1.3 In Case of Problems
If after making and saving system changes with Setup, you discover that your computer no
longer is able to boot, the Award BIOS supports an override to the CMOS settings that
resets your system to its default configuration.
The best advice is to alter only settings that you thoroughly understand. In particular, do not
change settings in the Chipset screen without a good reason. BCM Advanced Research Inc.
or your system manufacturer for the best performance and reliability has carefully chosen the
Chipset defaults. Even a seemingly small change to the Chipset setup may cause the system
to become unstable.

4.3.1 Date
The BIOS determines the day of the week from the other date information. This field is for
information only. Press the left or right arrow key to move to the desired field (date, month,
year). Press the PgUp or PgDn key to increment the setting, or type the desired value into
the field.
4.3.2 Time
The time format is based on the 24-hour military-time clock. For example, 1 p.m. is
13:00:00. Press the left or right arrow key to move to the desired field. Press the PgUp or
PgDn key to increment the setting, or type the desired value into the field.
4.3.3 Hard Disks
The BIOS supports up to four IDE drives. This section does not show information about
other IDE devices, such as a CD-ROM drive, or about other hard drive types, such as SCSI
drives.
36
4. BIOS Setup
NOTE: We recommend that you select type AUTO for all drives.
The BIOS can automatically detect the specifications and optimal operating mode of almost
all IDE hard drives. When you select type AUTO for a hard drive, the BIOS detects its
specifications during POST, every time the system boots.
If you do not want to select drive type AUTO, other methods of selecting the drive type are
available:
1. Match the specifications of your installed IDE hard drive(s) with the preprogrammed
values for drive types 1 through 45.
2. Select USER and enter values into each drive parameter field.
3. Use the IDE HDD AUTO DECTECTION function in Setup.
Here is a brief explanation of drive specifications:
Ø Type: The BIOS contains a table of pre-defined drive types. Each defined drive type
has a specified number of cylinders, number of heads, write precompensation factor,
landing zone, and number of sectors, Drives whose specifications do not accommodate
any pre-defined type are classified as type USER.
Ø Size: Disk drive capacity (approximate). Note that this size is usually slightly greater
than the size of a formatted disk given by a disk-checking program.
Ø Cyls: Number of cylinders
Ø Head: Number of herds
Ø Precomp: Write precompensation cylinder
Ø Landz: Landing zone
Ø Sector: Number of sectors
Ø Mode: Auto, Normal, large, or LBA
Ø Auto: The BIOS automatically determines the optimal mode.
Ø Normal: Maximum number of cylinders, heads, and sectors supported are 1024, 16 and
63.
Ø Large: For drives that do not support LBA and have more than 1024 cylinders.
Ø LBA (Logical Block Addressing): During drive accesses, the IDE controller
Ø Transforms the data address described by sector, head, and cylinder number
Ø into a physical block address, significantly improving data transfer rates. For drives
with greater than 1024 cylinders.

2.88M, 3.5 in3-1/2 inch double-sided drive; 2.88 megabyte capacity
4.3.5 Video
Select the type of primary video subsystem in your computer. The BIOS usually detects the
correct video type automatically. The BIOS supports a secondary video subsystem, but you
do not select it in Setup.
EGA/VGA
CGA 40Color Graphics Adapter, power up in 40 column mode.
CGA 80Color Graphics Adapter, power up in 80 column mode.
MONO
Enhanced Graphics Adapter/Video Graphics Array. For EGA,
VGA, SEGA, SVGA or PGA monitor adapters.
Monochrome adapter, includes high resolution monochrome
adapters.
4.3.6 Halt on
During the power-on self-test (POST), the computer stops if the BIOS detect a hardware
error. You can tell the BIOS to ignore certain errors during POST and continue the boot-up
process. Below are the selections:
No errorsPOST does not stop for any errors.
All errorsIf the BIOS detect any non-fatal error, POST stops and prompts you
to take corrective action.
All, But KeyboardPOST does not stop for a keyboard error, but stops for all other
errors.

errors.
All, But Disk/KeyPOST does not stop for a keyboard or disk error, but stops for all
other errors.
4.3.7 Memory
You cannot change any values in the Memory fields; they are only for your information. The
fields show the total installed random access memory (RAM) and amounts allocated to base
memory, extended memory, and other (high) memory. RAM is counted in kilobytes (KB:
approximately one thousand bytes) and megabytes (MB: approximately one million bytes).
RAM is the computer's working memory, where the computer stores programs and data
currently being used, so they are accessible to the CPU. Modern personal computers may
contain up to 64 MB, 128 MB, or more.
Base Memory
Typically 640 KB. Also called conventional memory. The DOS operating system and
conventional applications use this area.
Extended Memory
Above the 1-MB boundary. Early IBM personal computers could not use memory above 1
MB, but current PCs and their software can use extended memory.
Other Memory
Between 640 KB and 1 MB; often called High memory. DOS may load terminate-and-stayresident (TSR) programs, such as device drivers, in this area, to free as much conventional
memory as possible for applications. Lines in your CONFIG.SYS file that start with
LOADHIGH load programs into high memory.
Total Memory
System total memory is the sum of base memory, extended memory, and other memory.

4.4 BIOS Features Setup Menu
This screen (Figure 3) contains industry-standard options additional to the core PC AT BIOS.
This section describes all fields offered by Award Software in this screen. Some fields may
vary from those in your Setup program. Your system board designer may omit or modify
some fields.

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.
4.4.2 CPU Internal Cache
Cache memory is additional memory that is much faster than conventional DRAM (system
memory). Some CPU integrate a build-in Cache memory to speed up the data transfer. This
item allows you to enable or disable the inter Cache.
40
4. BIOS Setup
4.4.3 External Cache
Cache memory is additional memory that is much faster than conventional DRAM (system
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. The External Cache
field may not appear if your system does not have external cache memory.
4.4.4 Quick Power On Self Test
This allows you to enable or disable system self test when power on.
4.4.5 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, the BIOS now offers 10 different boot sequence
options of three drives each. In addition to the traditional drives A and C, options include
IDE hard drives D, E, and F; plus a SCSI hard drive and a CD-ROM drive.
4.4.6 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.
4.4.7 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.
4.4.8 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.
4.4.9 Booy Up System Speed
This item allows you to set the boot speed of your system.
4.4.10 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.
41
4. BIOS Setup
4.4.11 Typematic Rate (Chars/Sec)
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.
4.4.12 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.
4.4.13 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.
4.4.14 PCI/VGA Palette Snoop
Some display cards that are not standard VGA such as graphics accelerators or MPEG cards
may not show the correct colors, the setting can correct this problem once you set it to
Enabled, to default setting leave at Disabled.
4.4.15 Assign IRQ For VGA
Set this option to Yes to allocate an IRQ to VGA device on the PCI Bus. The setting are
Enabled or Disabled.

system board or on expansion boards. Disable the second channel if a second IDE connector
is not present or not in use.
4.7.5 PCI IRQ Activated By
Leave the IRQ trigger set at Level unless the PCI device assigned to the interrupt specifies
Edge-triggered interrupts.
4.7.6 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.
4.7.7 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.
