 Hardware Dimension is 220mm x 230mm (8.66" x 9.0"); BabyAT Form Factor.

1-2 SOFTWARE POWER OFF CONTROL

The mainboard design supports Software Power Off Control feature through the SMM code in the BIOS under Windows 95/98, and MS-DOS operation system environment. ( It needs to use with the ATX power supply.)

First, you should connect the power switch cable to the connector “PS-ON” on the

mainboard. In the BIOS screen of POWER MANAGEMENT SETUP’, choose “User Defined” (or “Min. Power Saving” or “Max. Power Saving”) in ‘Power Manager’ and choose “Yes” in ‘PM Control by APM’.

In Windows 95/98, if you would like to power off the system, you just choose “shutdown the computer ?” in the “Shut Down Windows“ from Windows 95/98, then the system power will be off directly and become the stand-by status. If you would like to restart the system, just press the power switch button, and the system will be powered on.

Note : If you will leave your system for several days, we suggest you use hardware power off to shutdown your system.

1-3 Wake-On-LAN

The remote Wake-On-LAN mode of operation is a mechanism that uses Advanced Micro Device Magic Packet technology to power up a sleeping workstation on the network. This mechanism is accomplished when the LAN card receives a specific packet of information, called a Magic Packet, addressed to the node on the network. For additional protection, Secure ON is an optional security feature that can be added to the Magic Packet that requires a password to power up the sleeping workstation. When the LAN card is in remote Wake-On-LAN mode, main system power can be shut down leaving power only for the LAN card and auxiliary power recondition.

The LAN card performs no network activities while in the remote Wake-OnLAN mode of operation. It only monitors the network for receipt of a Magic Packet. If a Magic Packet is addressed to the LAN card on the network, the LAN card wake up the system. If the Secure ON feature has been enabled, the password added to the Magic Packet is also verified prior to waking up the system.

CAUTION :

For Wake-on-LAN, the +5V standby for the power supply must be capable of delivering +5V ±5% at 720mA. Failure to provide adequate standby current when implementing Wake-on-LAN can damage the power supply. ( It needs to use with the ATX power supply.)

Before you enable Wake-on-LAN function, please check your power supply specification first to meet the above requirement or not.

Memory This category is display-only which is determined by POST

(Power On Self Test) of the BIOS. Base Memory The POST will determine the amount of base (or conventional) memory installed in the system. The value of the base memory is typically 512K or 640K based on the memory installed on the motherboard. Extended Memory How much extended memory is present during the POST. This is the amount of memory located above 1MB in the CPU‘s memory address map.

Other Memory This refers to the memory located in the 640K to 1024K address space. This is memory that can be used for different applications. DOS users this area to load device drivers in an effort to keep as much base memory free for application

programs. The BIOS is the most frequent user of this RAM area since this is where it shadows RAM.

This screen is a list of system configuration options. Some of them are defaults required by the

mainboard's design, others depend on the features of your system.

Allows you to set each mode individually.

When not disabled, each of the ranges are

from 1min. to 1hr. except for HDD Power

Down which ranges from 1 to 15min. and

disable

If you would like to use Software Power-off Control function, you cannot choose“ Disabled ”here, and should select “Yes” in PM Control by APM.

PM Control When enabled, an Advanced Power Management device by APM will be activated to enhance the Max. Power Saving

Mode and stop the CPU internal clock. If the Max. Power Saving is not enabled, this will be shown as NO.

Video Off When enabled, this feature allows the VGA adapter to operate Option in a power saving mode.

Always On Monitor will remain on during power saving

modes.

Suspend Monitor blanked when the systems enters the

Suspend mode.

Susp, Stby Monitor blanked when the system enters Suspend

or Standby mode.

All Modes Monitor blanked when the system enters any

power saving mode.

Video Off This determines the manner in which the monitor is blanked.

This selection will cause the system to

turn off the vertical and horizontal

sync. ports and write blanks to the

MODEM Use IRQ This item determines the IRQ in which the MODEM can be used.

The choice : 3,4,5,7,9,10,11,NA.

Soft-Off by Instant-off : When push the power button, the system power will

PWR-BTTN be off immediately. Delay 4 sec : when push the power button, it

will enter suspend mode. We need to push the power button and hold for 4 seconds to turn off the power.

The Following 4 modes are Green PC power saving functions which are only user configurable when ‘User Defined’ power management has been selected.

HDD Power Down When enabled and after the set time of system inactivity, the

hard disk drive will be powered down while all other devices remain active.

Doze Mode When enabled and after the set time of system inactivity, the CPU clock will run at slower speed while all other devices

still operate at full speed.

Suspend Mode When enabled and after the set time of system inactivity, all

devices except the CPU will be shut off.

VGA/LPT & COM These are I/O events whose occurrence can prevent the system HDD & FDD/ from entering a power saving mode or can awaken the system DMA/master from such a mode. In effect, the system remains alert for anything

which occurs on a device which is configured as on, even when the system is in a password down mode. When an I/O device wants to gain the attention of the operating system, it signals this by causing an IRQ(Interrupt ReQuest) to occur. When the operating system is ready to respond to the request, it interrupts itself and performs the service. When set to off, activity will neither prevent the system from going into a power management mode nor awaken it.

Modem Ring Enabled : when system in suspend mode, it can be wake up Resume by modem.

Disabled : it cannot be wake up by modem.

RTC Alarm When enabled, two additional lines will added to the screen : Resume Date (of Month) Alarm; Time (hh:mm:ss) Alarm to let user set

The desired date and time. After power off, the system will automatic power on at the specified date and time.

Primary INTR It enables/disables the IRQ3 to IRQ15 PM events.

PCI IDE IRQ This allows you to configure your system to the type of IDE disk

Map To controller in use. By default, Setup assumes that your controller is Primary IDE INT# an ISA device rather than a PCI controller. The most apparent Secondary IDE difference is the type of slot being used. If you have equipped your INT# system with a PCI controller, changing this allows you to specify

which slot holds the controller and which PCI interrupt (A,B,C,D) is associated with the connected hard disk. This setting refers to the hard disk drive itself, rather than individual partitions. Since each IDE controller supports two separate hard drives, you can select the INT# for each. Again, you will note that the primary has a lower interrupt than the secondary as described in “ lot x Using INT#”

above. Select ‘PCI Auto’ allows the system to automatically

determine how your IDE disk system is configured.

Assign IRQ for When this items is enabled, the system will assign an IRQ for USB USB. If this item is disabled, the USB will not occupy an

IRQ; therefore the IRQ of USB will be released for other usage.

Assign IRQ for When this items is enabled, the system will assign an IRQ for VGA VGA. If this item is disabled, the VGA will not occupy an

IRQ; therefore the IRQ of VGA will be released for other usage.
