[. . . ] Chapter 3
Award BIOS
This chapter tells how to configure the system parameters. You may update your BIOS via AWARD Flash Utility.
Important: Because the BIOS code is the most often changed part of the mainboard design, the BIOS information contained in this chapter (especially the Chipset Setup parameters) may be a little different compared to the actual BIOS that came with your mainboard. These changes are implemented to further enhance system performance.
3. 1
Entering the Award BIOS Setup Menu
The BIOS setup utility is a segment of codes/routines residing in the BIOS Flash ROM. This routine allows you to configure the system parameters and save the configuration into the 128 byte CMOS area, (normally in the RTC chip or directly in the main chipset). [. . . ] Any activity detected returns the system to full power. The system activity (or event) is detected by monitoring the IRQ signals.

Standby Mode
Disabled 20 Sec 1 Min 5 Min 10 Min 15 Min 20 Min 30 Min 40 Min
This item lets you set the period of time after which the system enters into Standby mode. In this mode, CPU clock slows down, hard disk will be shut off and the monitor power-saving feature activates. Any activity detected returns the system to full power. The system activity (or event) is detected by monitoring the IRQ signals.

Suspend Mode
Disabled 20 Sec 1 Min 5 Min 10 Min 15 Min 20 Min 30 Min 40 Min
Suspend Mode
This item lets you set the period of time after which the system enters into Suspend mode. In this mode, CPU clock stops, all other devices will be shut off. Any activity detected returns the system to full power. The system activity(or event) is detected by monitoring the IRQ signals.

If your ISA card is not PnP compatible and requires a special IRQ to support its function, set the selected IRQ to Legacy ISA . This setting informs the PnP BIOS to reserve the selected IRQ for the installed legacy ISA card. Take note that PCI cards are always PnP compatible (except old PCI IDE card).

Some old PCI IDE add-on cards are not fully PnP compatible. These cards require you to specify the slot in use to enable BIOS to properly configure the PnP resources. This function allows you to select the PCI slot for any PCI IDE add-on card present in your system. Set this item to Auto to allow BIOS to automatically configure the installed PCI IDE card(s).

3. 11 IDE HDD Auto Detection
If your system has an IDE hard drive, you can use this function to detect its parameters and enter them into the "Standard CMOS Setup" automatically. This routine only detects one set of parameters for your IDE hard drive. Some IDE drives can use more than one set of parameters. If your hard disk is formatted using different parameters than those detected, you have to enter the parameters manually. [. . . ]
