1-2 Software Power Off Control
6240M Mainboard supports Software Power Off Control feature through
the SMM code in the BIOS under Windows 95/98, and MS-DOS operation
system environment. This is Intel ATX form factor feature and you should use
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 pick up “Yes” in ‘PM Control by APM’.
In Windows 95/98, to power off the system, you just need to choose
“shutdown the computer ?” in the “Shut Down Windows“ from Windows 95/98.
Then the system power will be off directly, and stay at 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 are going to leave your system idle for several days, we suggest you use
hardware power off to shutdown your system.
* Under Software power off control, the status of Power LED Light
depends on the setting of JP5.
If you set JP5 to “pin1-2” position, it is blinking. Otherwise, it is light
off.
Status Power LED Light Turbo LED Light
Software power off
control Blinking (JP5, pin1-2) Light off (JP5, pin2-3) Light off
APM mode Light on Light on
System running Light on Light on
1-3 Fan Off Control
With fan-off function, the CPU cooling fan can turn off automatically even
when the system is in suspend mode. This function can reduce energy
consumption and system noise.
Because it is a feature of advanced BIOS, you should set this option
enabled through “Power Management Setup” from the BIOS setup screen. (An
ATX power supply is needed to achieve this function.)

1-4 Running 100 MHz CPU Bus on mainboard (JP11)
The mainboard provides Jumper 11 that allows you to set your CPU host
clock and perform CPU overclock function. When JP11 is ‘closed’, the system
will automatically detect the CPU host clock, for instance 66MHz and 100MHz.
When JP11 is ‘open’ it is for 66MHz CPU overclock to 100MHz.
We recommend that users should use Intel Pentium

II/III 100 MHz CPU,
running at 350, 400, 450 and 500MHz internal clock speed. Moreover, the
SDRAM memory module must be 8 nano-second (Maximum Frequency 125
MHz) speed of memory –die or less. However, based on Intel’s design, we don’t
recommend users to run over 100MHz CPU host bus.
Please note that the default setting of Jumper 11 is ‘closed’.
Jumper 11BASE CLK
ClosedAuto (default)
Open Overclock (66MHzà100MHz)
(a) Pin Closed (b) Pin Open
Slot 1
-If you would like to run over 100MHz CPU host bus, like 112 and 124MHz, please
set “CPU Host Clock” in “CHIPSET FEATURES SETUP” from the BIOS setup
screen. If the system can’t boot up at CPU frequency that has been set, you can
press the ‘Insert” key to clear up the set frequency. After restarting the system, it
will operate at the default frequency.

1-5 SB-Link Sideband Signals
In order to migrate the legacy Sound Blaster compatible audio to the PCI
bus, EMU8008 incorporates a pair of SB-Link request/grant sideband signals
(PCPCIR EQN and PCPCIGNTN) to interface to the PCI bus. SB-Link is a
mechanism that was defined and developed by INTEL as a docking solution
which allows ISA slots to exist in docking stations connected to desktop PC PCI
bus.
ISA Slots PCI Slot SB-Link 2x3 sideband header, sound will also
has a 2x3 header and a cable.
1-6 Modem Ring On
With Modem Ring On function, the computer can wake up remotely
through the connected modem. This function enables users to access their
computer data from anywhere in the world. But users have to set “Resume by
Ring” with ‘enabled’ in “Power Management Setup” from the BIOS setup
screen. ( An ATX power supply is needed to achieve this function.)

1-8 Wake-On-LAN
The remote Wake-On-LAN mode of operation is a mechanism that uses
Advanced Micro Device Magic Packet technology to power on 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 on the sleeping workstation. When 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-On-LAN 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.
You should select two kinds of PCI Ethernet cards with WOL function.
One is Intel and the other is with PME signal supporting. And you can set
“PCI PME# Function” this function enabled through “ Power Management
Setup” from the BIOS setup screen.
1-9 Thermister (option)
This means that user can monitor the CPU temperature through
thermister.
When setting up the thermister (refer to Appendix B), the BIOS will load
the CPU temperature automatically. There is a choice of the warning beep
sound if the user set the option on. If the CPU temperature overheated, the user
will get the notice .This time you should shut down computer and check your
devices. Or you can connect with you dealer.
Therefore, monitoring the CPU temperature is the thermister’s job.
Note: If you would like to enable the function of hardware monitor, to set up
thermister beforehand is necessary.

1-10 LDCM （LANDesk Client Manager）(option)
The mainboard built-in controller support Intel LDCM. LDCM can satisfy
users who want manageable systems that can interact automatically with the
user. Client manager is the answer, enabling both administrators and clients to
manage systems. The features of LDCM are as following :
※View system inventory
Client Manager enables you to view hundreds of inventoried items. Some of
these items are software related, while many others are hardware related.
※View DMI-compliant component information
Client manager enables you to view component information that is compliant
with the Desktop Manager Interface
（
DMI
）
. This means you can manage
third-party DMI-compliant components which did not include Client
manager.
※Back up and restore system configuration files.
Client Manager enables you back up and restore system configuration files.
Whenever you plan on changing the system configuration , you can make a
backup set. If the system no longer works correctly, after you the change
the system configuration , you can simply restore the system configuration
with the backup set.
※Troubleshoot
Since Client manager enables you to view the system inventory, you can easily
troubleshoot system problems.
※Receive notifications for system events
Client manager enables you to receive notification of certain system events. For
example, if the system is running low on virtual memory, you are notified of
the potential problem.
※Transfer files to and from client workstations
As an administrator, you have the ability to transfer files to and from client
workstation. This is helpful, for example, when you need to update a client
workstation driver.
※Remotely reboot client workstations
Administrator also have the ability to remotely reboot a workstation. This is
helpful when you want your system configuration changes to take effect.
