Technical information

AWARD BIOS 4-13

The EP-5ATXA-M supports HDD Power Down, Doze and standby power savingfunctions

when Intel Pentium Processor is installed. In addition, the suspend function

is supported when the JP14's sleep (sleep ref. Figure1-1) is closed to enter the green

function. The detailed descriptions of these functions are provided in the next page.

HDD Power Down

When the system stops reading or wiriting HDD, the timer starts to count. The system

will cut off the HDD power when timer runs out of time. The system will not resume

operation until either a read from or a wirte to HDD command is executed again.

Doze Mode

The system hardware will drop down CPU clock from normal working speed

when Doze mode timeout occurrs.

Standby Mode

When the system standby mode timer runs out, it will enter the standby mode and

retain CPU at slow working speed. The screen will be blanked out.

Suspend Mode

When the system suspend timer times out, the system will enter the suspend mode

and the chipset will stop CPU clock immediately. The power consumption in

Suspend Mode is lower than in standby mode. The screen is also blanked out.

PM Events:

AWARD BIOS defines Reload Global Timer Events in the power management mode

(Doze,standby & suspend). The user can initialize any PM Events to be "Enabled" or

"Disabled". When the system detects all of the enabled events which do not have any

activity, it will start the system Doze timer first if the "Power Management" isn't

"Disabled". Once the system Doze timer is timed out, it will process doze power saving

procedure by starting the system standby timer. When the standby timer ran out and

all of the "Enabled" events remains silent, the system will enter the standby mode. By

now, the system will not only process the standby power saving procedures but also

start the system suspend timer. When the suspend timer times out, all of the CPU clock

will stop by dropping system clock down to zero and remains this way until any one

of the "Enabled" event occurrs.

4-5 Plug & Play/PCI Configuration

The PnP/PCI configuration program is for the user to modify the PCI/ISA IRQ signals when

various PCI/ISA cards are inserted in the PCI or ISA slots.

WARNING : Any misplacing IRQ could cause system not able to pick up the rescouces.
