[. . . ] 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. Power Management Standby Mode 3-16 Award BIOS 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. Power Management 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. Power Management Power Management Power Management Power Management COM Ports Activity Enabled Disabled COM Ports Activity LPT Ports Activity HDD Ports Activity VGA Activity To enable or disable the detection of COM port, LPT, HDD, VGA activities for power down state transition. 3-17 Award BIOS Power Management Power Management Power Management Power Management Power Management Power Management Power Management Power Management Power Management Power Management Power Management Power Management IRQ2 (COM2) Enabled Disabled IRQ3 (COM2) IRQ4 (COM1) IRQ5 (LPT2) IRQ6 (Floppy Disk) IRQ8 (RTC Alarm) IRQ9 (IRQ2 Redir) IRQ10 (Reserved) IRQ11 (Reserved) IRQ12 (PS/2 Mouse) IRQ13 (Coprocessor) IRQ14 (Hard Disk) IRQ15 (Reserved) To enable or disable the detection of IRQ event for power down state transition. Note that OS2 has periodically IRQ8 (RTC) interruptions, If IRQ8 is not set to Disabled, OS/2 may fail to go into Doze/Standby/Suspend mode. 3-18 Award BIOS 3. 6 PNP/PCI Configuration Setup The PNP/PCI Configuration Setup allows you to configure the ISA and PCI devices installed in your system. The following screen appears if you select the option "PNP/PCI Configuration Setup" from the main menu. ROM PCI/ISA BIOS (XXXXXXXX) PNP/PCI CONFIGURATION SETUP AWARD SOFTWARE, INC.

Set this to Auto to enable the autoconfiguration function. 3-19 Award BIOS PNP/PCI Configuration Reset Configuration Data Enabled Disabled Reset Configuration Data In case conflict occurs after you assign the IRQs or after you configure your system, you can enable this function, allow your system to automatically reset your configuration and reassign the IRQs.

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).

This setting informs the PnP BIOS to reserve the selected DMA channel for the installed legacy ISA card. Take note that PCI card does not require DMA channel. 3-20 Award BIOS PNP/PCI Configuration PCI IRQ Actived By Level Edge PCI IRQ Actived By This option lets the user set when to activate the PCI IRQ. The available settings are Edge and Level. The Edge is the start of the signal and Level is the point at which the signal is high. The default is Level. PNP/PCI Configuration PCI IDE 2nd Channel PCI IDE 2nd Channel Enable this option if you installed an IDE controller board into one of the PCI slots on the system board, Enabled and assign it as your secondary IDE controller. Disabled Otherwise, set this parameter to Disabled. PNP/PCI Configuration PCI IDE IRQ Map To ISA PCI-Slot1 PCI-Slot2 PCI-Slot3 PCI-Slot4 PCI-Auto PCI IDE IRQ Map To 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). PNP/PCI Configuration PNP/PCI Configuration Primary IDE INT# A B C D Primary IDE INT# Secondary IDE INT# These two items, in conjunction with item "PCI IDE IRQ Map To", specify the IRQ routing of the primary or secondary channel of the PCI IDE add-on card (not the onboard IDE). [. . . ] The screen displays a message confirming that the password has been disabled. 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. [. . . ]
