3-4-1 The Description of the Power Management
• Power Management mode selection:
Disabled: The system operates in NORMAL conditions (Non-GREEN), and the Power Management function is disabled.
Max.saving: This mode will maximize the power saving capability.
Min.saving: This mode will minimize the power saving capability.
User define: Allow user to define timeout parameters to control power saving timing. Refer item shown below:
• Timeout parameters:
HDD Standby
HDD Standby timer can be set from 1 to 15 minute(s).
System Doze
The "System Doze" mode timer starts to count when there is no "PM events" occurred. The valid timeout setting is from 1 minute up to 1 hour.
System Standby
The "Standby" mode timer starts to count when "System Doze" mode timer timed out and no "PM events" occurred. Valid range is from 1 minute up to 1 hour.
System Suspend
This function works only when the Pentium CPU is installed. The timer starts to count when "System Standby" mode timer timed out and no "PM Events" occurred. Valid range is from 1 minute up to 1 hour.
3-4-2 Description of the Green Functions
This motherboard supports HDD Power Down, Doze and standby power saving functions when Intel Pentium Processor CPU is installed. The suspend function is also supported when the SMI switch is short (ref. page 13). The detail description of these functions are provided as following:
HDD Standby Mode
When system stop reading or writing HDD, the timer starts to count. The system will cut off the HDD power when timer ran out of time. The system will not resume operation until either a read from or a write to HDD command is executed again.
Doze Mode
The system hardware will drop down CPU clock from normal working speed when Doze mode timeout occurred.
Standby Mode
When the system standby mode timer ran 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 time 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 15 PM Events in the power management mode (Doze, standby & suspend). The user can initial any PM Events to be "Enable" or "Disable". When the system detects all of the enabled events 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 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 time out, all of the CPU clock will be stopped by dropping system clock down to zero and remains this way until any one of the "Enabled" event occurred.
3-5 PNP/PCI CONFIGURATION SETUP

IRQxx assigned to
These fields indicate whether or not the displayed IRQ for each field is being used by a Legacy (non-PnP) ISA card. Two options are available: “PCI/ISA PnP” and “Legacy ISA”. The first option the default value, indicates either that the displayed IRQ is not used or an PCI/ISA PnP is being used to determine if an ISA card is using that IRQ. Second option is for Legacy ISA card that requires a unique IRQ, and you are not using an PCI/ISA PnP, you must set the field for that IRQ to Legacy ISA.
For example: If you install a Legacy ISA card that requires IRQ10 lets say, then set “IRQ10 assigned to Legacy ISA”.
DMAxx assigned to
These fields indicate whether or not the displayed DMA channel for each field is being used by a Legacy (non-PnP) ISA card. Available options include: “PCI/ISA PnP” and ”Legacy ISA“. When is option ”PCI/ISA PnP“ indicates either that the displayed DMA channel is not used or an PCI/ISA PnP being used to determine if an ISA card is using that channel. If you install a Legacy ISA card that requires a unique DMA channel, and you are not using an PCI/ISA PnP, you must set the field for that channel to “Legacy ISA“.

This item lets you configure the system so that a password is required each time the system boots or an attempt is made to enter the Setup program (Refer to Figure 3-3 for the details). Supervisor Password allows you to change all CMOS settings but the User Password setting doesn’t have this function. The way to set up the passwords for both Supervisor and User are as follow:
1. Choose either Supervisor Password or User Password in the Main Menu and press <Enter>. The following message appears:
“Enter Password:”
2. The first time you run this option, enter your password up to only 8 characters and press <Enter>. The screen does not display the entered characters. For no password just press <Enter>.
3. After you enter the password, the following message appears prompting you to confirm the password:
“Confirm Password:”
4. Enter exact the same password you just typed again to confirm the password and press <Enter>.
5. Move the cursor to Save & Exit Setup to save the password.
6. If you need to delete the password you entered before, choose the Supervisor Password and Press <Enter>. It will delete the password that you bad before.
7. Move the cursor to Save & Exit Setup to save the option you did, otherwise the old password will still be there when you turn on your machine next time.
3-10 IDE HDD AUTO DETECTION
The "IDE HDD AUTO DETECTION" utility is a very useful tool especially when you do not know which kind of hard disk type you are using. You can use this utility to detect the correct disk type and install in the system automatically. Also you can set HARD DISK TYPE to “Auto” in the STANDARD CMOS SETUP to have same result. The BIOS will Auto-detect the hard disk size and model on display during POST.

NOTE: HDD Modes
The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE
NORMAL mode
Generic access mode in which neither the BIOS nor the IDE controller will make any transformations during accessing.
The maximum number of cylinders, head & sectors for NORMAL mode are 1024, 16 & 63.
no. Cylinder (1024)
x no. Head ( 16)
x no. Sector ( 63)
x no. per sector ( 512)
528 Megabytes
If user set this HDD to NORMAL mode, the maximum accessible HDD size will be 528 Megabytes even though its physical size may be greater than that!
LBA (Logical Block Addressing) mode
A new HDD accessing method to overcome the 528 Megabyte bottleneck. The number of cylinders, heads & sectors shown in setup may not be the number physically contained in the HDD.
During HDD accessing, the IDE controller will transform the logical address described by sector, head & cylinder into its own physical address inside the HDD.
The maximum HDD size supported by LBA mode is 8.4 Gigabytes which is obtained by the following formula:
no. Cylinder (1024)
x no. Head ( 255)
x no. Sector ( 63)
x bytes per sector ( 512)
8.4 Gigabytes
LARGE mode
Extended HDD access mode supported by Award Software.
Some IDE HDDs contain more than 1024 cylinder without LBA support (in some cases, user do not want LBA). The Award BIOS provides another alternative to support these kinds of LARGE mode:
CYLS. HEAD SECTOR MODE
1120 16 59 NORMAL
560 32 59 LARGE
BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by dividing it by 2. At the same time, the number of heads is multiplied by 2. Reverse transformation process will be made inside INT 12h in order to access the right HDD address the right HDD address!
Maximum HDD size:
no. Cylinder (1024)
x no. Head ( 32)
x no. Sector ( 63)
x bytes per sector ( 512)
1 Gigabytes
NOTE:
To support LBA or LARGE mode of HDDs, there must be some softwares involved. All these softwares are located in the Award HDD Service Routine (1NT 13h). It may be failed to access a HDD with LBA (LARGE) mode selected if you are running under a Operating System which replaces the whole INT 13h.
UNIX operating systems do not support either LBA or LARGE and must set to the Standard mode. UNIX can support drives larger than 528MB.
3-11 SAVE & EXIT SETUP
The "SAVE & EXIT SETUP" option will bring you back to boot up procedure with all the changes you just made which are recorded in the CMOS RAM.

The "EXIT WITHOUT SAVING" option will bring you back to normal boot up procedure without saving any data into CMOS RAM. All of the old data in the CMOS will not be destroyed.
