PowerOn by PCI Card
When enabled, a PCI interface that receives a signal will wake up the system from soft
off and green mode.
5.
PowerOn by Modem/LAN
When enabled, a LAN/modem that receives a signal will wake up the system from soft
off and green mode. You should connect the modem to the COM port and turn on the
resume event in green mode.
6.
PowerOn by Alarm
When enabled, this setting allows the system to turn back on at a designated time of the
month. User must designate date of month and time of day. This function is only
available when using an ATX power supply and the Software Power-Off function to turn
off the computer. See the Software Power-Off feature in Section 2-3 of this manual for
instructions.
IRQs Activities Monitoring
This feature allows you to monitor a list of IRQ, Interrupt ReQuests. When an I/O device
wants to gain the attention of the operating system, it signals this by causing an IRQ to
occur. When the operating system is ready to respond to the request, it interrupts itself and
performs the service.
3-6 PNP/PCI Configurations
This section provides IRQ and DMA setting information. By choosing the PNP/PCI
Configuration option from the CMOS Setup Utility menu (Figure 3-1), the screen below
is displayed. This screen contains the manufacturer's default values for the motherboard.
PNP OS Installed
If you want to install a PNP compatible OS (such as Windows 95) set to Yes.
Reset Configuration Data:
If you want to reset CMOS IRQ divide hardware device, please selected to [

Resources Controlled By
When set to Manual the system BIOS will not refer to the ESCD for IRQ & DMA
information. Instead, it will refer to the items in the setup menu for assigning IRQ &
DMA. When set to Auto the system BIOS will refer to the ESCD for all legacy
information. ESCD (
Extended System Configuration Data
) provides a detailed format
of the configuration data structures stored in flash memory. Each data structure defines
the resources used by a device or a card in the system. This includes legacy and PCI/ISA
PnP devices.
PCI/VGA Palette Snoop
When set to [Enabled], multiple VGA devices operating on different buses can handle
data from the CPU on each set of palette registers on every video device. Bit 5 of the
command register in the PCI device configuration space is the VGA Palette Snoop bit (0
is disabled). Available options are [
Enabled
] and [
Disabled
].
Assign IRQ For VGA/USB
Available options: [
Enabled
] and [
Disabled
].
FDD IRQ Can Be Free
This function allows user to choose if the FDD IRQ can be freed up. The default setting
is [Yes] and this does not allow the IRQ to be free.
3-7 Frequency/Voltage Control
By choosing the Frequency/Voltage Control option from the CMOS Setup Utility menu
(Figure 3-1), the screen below is displayed. This sample screen contains the
manufacturer's default values for the motherboard.
Auto Detect PCI/DIMM Clk
Enabling this function will auto-detect PCI/DIMM clock.
Spread Spectrum
Available options: [
+/- 0.25%
], [
+/- 0.35%
], [
+/- 0.45%
], [
+/- 0.5%
].
CPU Clock
It is recommended to keep the default setting for stable system operation.
Overclocking:
This motherboard is designed to support overclocking. However, please
make sure your components are able to tolerate such abnormal setting,
while doing overclocking. Any attempt to operate beyond product
specifications is not recommended. We do not guarantee the damages or
risks caused by inadequate operation or beyond product specifications.
3-8 Load Fail-Safe Defaults
Load Fail-Safe Defaults loads the default BIOS values directly from the CMOS Setup
Utility menu (Figure3-1). If the stored record created by the setup program becomes
corrupted and therefore unusable, these defaults will be loaded automatically when you
turn on the computer.
3-9 Load Optimized Defaults
Load Optimized Defaults loads the default system values directly from the CMOS Setup
Utility menu (Figure3-1). If the stored record created by the setup program becomes
corrupted and therefore unusable, these defaults will be loaded automatically when you
turn on the computer.
