System BIOS
Setup
After you have configured the system board and
assembled all the components, you need to enter the system configuration
information to the system BIOS through the Award PnP BIOS Setup programs.
This Award PnP BIOS Setup program and the system configuration information
are embedded in the system board and it is backup by the Dallas Real Time
Clock.
Due to frequent update of system BIOS, the actual options available
in your system board BIOS setups may vary comparing with this manual. If
technically necessary, we would provide a special insert for instruction
of the difference in regard to any changes of the BIOS setup option.
Entering
BIOS Setup Program
Turn on or reboot the system. After
the system finished testing the on-board memory, the message "Hit
DEL if you want to run SETUP" will appear. Press "DEL" key
at this time will bring you into the BIOS Setup program.
Use "Arrow" keys to high-light
items, and use the "Enter" key to select option or you may use
the mouse to "Click" on item you want to select and change.
After the BIOS Setup program is entered,
you may want to choose the "Standard CMOS Setup" option for date,
time, and all disk drives information. If you have IDE Hard Drive(s) installed,
the "IDE HDD Auto Detection" option can be used to automatically
enter your hard drive(s) information.
At any time you may press "ESC"
key to exit the window, and choose the "Exit Without Saving"
option to keep the original configuration.
Load Setup Defaults
There is a set of BIOS values stored
in the ROM files: The "Setup" default values The "Setup"
default values are those settings which should provide optimum performance
for the system. They are the best case default values. This set of default
values can be loaded by using the "Load Setup Defaults" option
in the main BIOS menu when you first entered the setup utility.
Standard
CMOS Setup Option
Primary Master & Slave, Secondary
Master & Slave Drive Types According to your actual equipment,
you can select the type of hard disks for C, D, E, & F from 'Not Installed'
to type 46 for standard hard disks. As for type 47, user may define by
himself. If a ATAPI IDE CD-ROM is connected to any on-board IDE port, the
HARD DISKS "Type" should be set to "None". The DOS
CD-ROM driver or the Win95 built-in driver will handle the communication
by themselves. You may also use the "IDE HDD Auto Detection"
option in the Main Menu to allow the system to detect and enter these information
for you.
It is strongly recommended that
the HARD DISK "Type" and "Mode" be set to "Auto"
to allow the BIOS to detect and configure the hard disk(s) since hard disks
are becoming increasingly complicated. If the "Auto" modes
are enabled, the BIOS will perform a very reliable operation which it will
read the detail information about the hard disk that is embedded in the
drive by the manufacturer. This information is the true and optimal setting
for the drive and it will allow the BIOS to properly configure the system.
As it is proven, manually setting
the hard disk parameters often causes unnecessary troubles; from being
unable to format the disk to its full capacity to the system simply refusing
to boot. Therefore, it is only wise to leave these settings to "Auto"
and let the system do the job it does best.
Primary Master & Slave are the
2 IDE drives connected to the Primary IDE port as shown in the drawing
under the "Board Description" at the beginning of Chapter 2.
The Secondary Master & Slave are the 2 IDE drives connected to the
Secondary IDE port. If there are IDE device(s) installed on any of these
2 port, you must make sure the corresponding "On-Chip Primary PCI
IDE" and/or "On-Chip Secondary PCI IDE" in "Integrated
Peripherals Setup" is enabled.
Floppy Drives A & B
According to your actual equipment,
set floppy drive A & B whose five options are as highlighted.
BIOS Features
Setup
Virus Warning
This function, If enabled, will detect
boot sector viruses and warning will be given when a program attempted
to change boot sector information.
CPU Internal & External Cache
These options allows user to enable
or disable the on-board (External) and the on-chip(CPU Internal) cache
memories (SRAM) when special peripheral or software implemented indicate
such requirement. System over all speed will slow down considerably if
any of these options are disabled.
Security Option
This option allow a password be set
up so that a password will be needed to enter the CMOS Setup or to boot
the system including entering CMOS Setup. After this option is enabled,
you must use the "Password Setting" option in the main menu to
setup your password. If in any case the password is lost or forgotten,
the jumper JP7 - Clear CMOS can be used to clear the configuration.
WARNING - "JP7" will
clear and reset ALL and EVERY configuration parameters. Make sure you know
what you are doing or ask someone who does to help you.
Chipset Features
Setup
Most of the options in this group
have major influence to the system. If options are not set properly, it
may not only greatly affect the performance, but also it may bring the
system down unexpectedly in most cases. Therefore, it is only wise to leave
the defaults alone unless there are specific reason to do any change.
DRAM RAS# Precharge Time
DRAM must continually refreshed or
it will lose its data. This option allows you to determine the number of
CPU clocks allocated for the Row Address Strobe to accumulate its electrical
charge before the DRAM is refreshed. The default is "4".
DRAM Leadoff Timing
This number indicates the number of
CPU clocks allowed before reads and writes to DRAM are performed. The default
of 7 would set the leadoff timing for read to 7 clocks.
Fast RAS to CAS Delay
When DRAM is refreshed, both rows
and columns are addressed separately. This option allows you to determine
the timing of the transition from RAS to CAS. The default is "2"
DRAM Read (EDO/FP) / Write Burst
Timing
These 2 options set the timing for
Burst Mode reads and writes from and to the Fast Page Mode or EDO DRAM.
The burst read and write requests are generated by the CPU in four separate
parts. The four numbers indicate the actual data cycles. The lower the
timing number, the faster the system will address the memory. The defaults
are "x222/x333" & "x333" respectively.
Fast MA to RAS# Delay CLK, &
Refresh RAS# Assertion
The defaults for these options are
"1" and "5 ClKs" respectively.
Fast EDO Path select
If EDO DRAM is installed, the default
should be "Enabled", otherwise it is not applicable.
ISA Bus Clock
Read the instruction of JP13 in the
section "The Jumpers 3", and set this option accordingly.
SDRAM (CAS Lat/RAS-to-CAS)
If SDRAM is installed, the default
should be "3/3", otherwise it is not applicable.
Peer Concurrency
Peer Concurrency, when enabled, and
when there is a PCI Bus Master device installed, the CPU can run concurrently
with a PCI bus mastering peripheral. This achieves significant faster data
transfer rate without splitting resource utilization between CPU and bus
mastering device. The default is "Enabled"
Power Management
Setup
This system board is designed to fully
support the SMM/SMI power management protocol. When the "Power Management"
option is enabled, the system will enter into Doze and then Standby Mode
after the length of time set at the Timer options when no system activities
are detected.
Power Management
This option served as a master switch to turn-on the power management.
Doze, Standby, and Suspend Modes
Defined the length of time of continuous inactivity before the system enters
into different PM modes. The Suspend Mode is not implemented.
PCI Configuration
Setup
Unless otherwise required, do not
change the default setting.
Integrated
Peripherals Setup
IDE HDD Block Mode
This option, if enabled, instruct
the hard disk to read multiple blocks of data from the disk for one read
request. You must refer to your hard disk information to be certain your
drive support this feature.
IDE Primary & Secondary, Master
& Slave PIO Modes
Rather than have the BIOS issue a
series of commands to effect a transfer to or from the hard drive, PIO(Programmed
Input/Output) allows the BIOS to tell the hard drive controller what it
wants and lets the controller and the CPU to perform the complete task
themselves. This method is simpler, more efficient, and so is faster. The
BIOS supports five modes(0 through 4) and can be set to "Auto"
for each individual hard drive.
Warning : The default for the PIO
Modes are "Auto", if you manually set this parameter to a mode
that your hard drive does not support, it will cause the HDD to crash,
lost data, and/or trash your hard drive completely. If you are not 100%
certain, or your hard drives does not meet the ATA specification, set the
PIO Mode to "0" for that hard disk.
Primary & Secondary PCI IDE,
FDD Controller, Serial Port 1 & 2
Use these options to enable or disable
the respective on-board controllers.
On-Board Parallel Port, Parallel
Mode, and ECP DMA Channel
Use DMA LPT port address can be selected
by using the first option. The second option allows the setting of the
enhanced modes for the parallel port. If "ECP" or "EPP+ECP"
is enabled in the "Parallel Mode" option, use the "ECP Mode
Use DMA" to select DMA channel for the ECP Mode.
Exiting Setup
Utility
At this point, you can either choose
to confirm your setup entries and exit by using "ESC" key and
taking the "Save & Exit Setup" or the "Exit Without
Saving" option to restore the original setup parameters and exit.
After you highlight the desired option
and press <<ENTER>>, the system will reset itself. The new
or original setup parameters, depend on the option which you have chosen,
will become the current setting.
