period, system will temporarily enter into Suspend Mode
enabling you to restart the system at once.
This option allows you to select the type of power loss function.
The options available are On, Off. The default value is “Off”.
This section describes configuring the PCI bus system. PCI, or
Personal Computer Interconnect, is a system which allows I/O devices
to operate at speeds nearing the speed the CPU itself uses when
communicating with its own special components. This section covers
some very technical items and it is strongly recommended that only
experienced users should make any changes to the default settings.
z PNP OS Installed
Select Yes if the system operating environment is Plug-and-Play
aware (e.g., Windows 95). The default value is “No”.
z Reset Configuration Data
Normally, you leave this item Disabled. Select Enabled to reset
Extended System Configuration Data (ESCD) when you exit Setup
or if installing a new add-on cause the system reconfiguration a
serious conflict that the operating system can not boot. Options are:
“Enabled, Disabled”.
z Resources Controlled By
The Award Plug and Play BIOS can automatically configure all
boot and Plug and Play-compatible devices. If you select Auto, all
interrupt request (IRQ), DMA assignment, and Used DMA fields
disappear, as the BIOS automatically assigns them. The default
value is “Manual”.
When resources are controlled manually, assign each system
interrupt to one of the following types in accordance with the type
of devices using the interrupt:
1. Legacy ISA Devices compliant with the original PC AT bus
specification, requiring a specific interrupt (such as IRQ4 for serial
port 1).
2. PCI/ISA PnP Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.
The default value is “PCI/ISA PnP”.
z DMA Resources
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:
Legcy 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.
The default value is “PCI/ISA PnP”.
z Memory Resources
This sub menu can let you control the memory resource.
z PCI/VGA Palette Snoop
Some non-standard VGA display cards may not show colors
properly. This item allows you to set whether MPEG ISA/VESA
VGA Cards can work with PCI/VGA or not. When enabled, a
PCI/VGA can work with a MPEG ISA/VESA VGA card; when
disabled, a PCI/VGA cannot work with a MPEG ISA/VESA Card.
This section supports hardware monitering that lets you monitor those
parameters for critical voltages, temperatures and fan speed of the
board.
z Current CPU Temperature
These read-only fields reflect the functions of the hardware thermal
sensor that monitors the chip blocks and system temperatures to
ensure the system is stable.
This option allows you to load the default values to your system
configuration. These default settings are optimal and enable all high
performance features.
To load SETUP defaults value to CMOS SRAM, enter “Y”. If not, enter
“N”.
You can set either supervisor or user password, or both of then. The
differences between are:
1. Supervisor password: can enter and change the options of the
setup menus.
2. User password: just can enter but do not have the right to change
the options of the setup menus.
When you select this function, the following message will appear at the
center of the screen to assist you in creating a password.
ENTER PASSWORD:
Type the password with eight characters at most, and press <Enter>.
The password typed will now clear any previously entered password
from CMOS memory. You will be asked to confirm the password. Type
the password again and press <Enter>. You may also press <Esc> to
abort the selection and not enter a password.
To disable password, just press <Enter> when you are prompted to
enter password. A message will confirm the password being disabled.
Once the password is disabled, the system will boot and you can enter
Setup freely.
PASSWORD DISABLED.
When a password is enabled, you have to type it every time you enter
Setup. This prevents any unauthorized person from changing your
system configuration.
Additionally when a password is enabled, you can also require the
BIOS to request a password every time the system reboots. This would
prevent unauthorized use of your computer.
You determine when the password is required within the BIOS
Features Setup Menu and its Security option. If the Security option is
set to “System”, the password is required during boot up and entry into
Setup. If set as “Setup”, prompting will only occur prior to entering
Setup.
This allows you to determine whether or not to accept the modifications.
Typing “Y” quits the setup utility and saves all changes into the CMOS
memory. Typing “N” brigs you back to Setup utility.
Select this option to exit the Setup utility without saving the changes
you have made in this session. Typing “Y” will quit the Setup utility
without saving the modifications. Typing “N” will return you to Setup
utility.
The watchdog timer makes the system auto-reset while it stops to work
for a period. The integrated watchdog timer can be setup as system
reset mode by program.
