[. . . ] 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. 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). The BIOS Setup Main Menu appears as follows. 3-1 AWARD BIOS ROM PCI/ISA BIOS (XXXXXXXX) CMOS SETUP UTILITY AWARD SOFTWARE, INC. [. . . ] Power On Suspend is the traditional Green PC suspend mode, the CPU clock is stop, all other devices are shut off. But power must be kept On to detect activities from modem, keyboard/mouse and returns the system to full power. Suspend to Hard Drive saves system status, memory and screen image into hard disk, then the power can be totally Off. Next time, when power is turned On, the system goes back to your original work within just few seconds. Refer to section 3. 16 "Suspend to Hard Drive" for more information". Power Management à Throttle Duty Cycle 3-21 AWARD BIOS Throttle Duty Cycle 12. 5 % 25. 0 % 37. 5 % 50. 0 % 62. 5 % 75. 0 % 87. 5 % Clock Throttling means at the Doze/Standby state, the CPU clock count in a given time (not the frequency) is reduced to the ratio specified in this parameter. For example, a 66MHz CPU clock remains the same 30ns clock period when system goes into Doze/Suspend. The chipset generates the STPCLK (stop clock) signal periodically to prevent CPU for accepting clock from clock generator. If the Slow Clock Ratio is set to 50%, the CPU will only receive 33M clock count in one second. This will effectively reduce CPU speed as well as CPU power. Power Management à VGA Active Monitor VGA Activity Monitor Enabled Disabled To enable or disable the detection of VGA activity for power down state transition. Power Management à Power Bottom Override Power Bottom Override Disabled Enabled This is a specification of ACPI and supported by hardware. When Enabled, the soft power switch on the front panel can be used to control power On, Suspend and Off. If the switch is pressed less than 4 sec during power On, the system will go into Suspend mode. If the switch is pressed longer than 4 sec, the system will be turned Off. The default setting is Disabled, soft power switch is only used to control On and Off, there is no need to press 4 sec, and there is no Suspend. Power Management à RTC WakeUp Timer 3-22 AWARD BIOS RTC WakeUp Timer Disabled Wake Up Power Off The RTC WakeUp Timer can be programmed at a specified date/time to wakeup the system. The Date/Time is set by " WakeUp Date (of Month)" and "WakeUp Time (hh:mm:ss)". For automatic power off, you can select the idle timer in "Doze Mode" + "Standby Mode" + "Suspend Mode" to power off after system is detected without any activities. Power Management à WakeUp Date (of Month) Date (of Month) Alarm 0 1 2 . . . . . . 30 31 This item selects the date of month to on which to wake up or power off the system. Set to 0 means everyday. Power Management à Wake Up Time (hh:mm:ss) Time (hh:mm:ss) Alarm 07:00:00 . . This item selects the time at which to wake up or power off the system. The format is hour:minute:second, note that hour is in 24 hours form. Power Management à IRQ 8 Clock Event IRQ 8 Clock Event Enabled Disabled To enable or disable the detection of IRQ8 (RTC) event for power down state transition. OS2 has periodically IRQ8 (RTC) interruptions, If IRQ8 is not set to Disabled, OS/2 may fail to go into Doze/Standby/Suspend mode. 3-23 AWARD BIOS Power Management à IRQ [3-7, 9-15], NMI IRQ [3-7, 9-15], NMI Enabled Disabled To enable or disable the detection of IRQ3-7, IRQ9-15 or NMI interrupt events for power down state transition. Power Management à Primary IDE 0 Power Management à Primary IDE 1 Power Management à Secondary IDE 0 Power Management à Secondary IDE 1 Power Management à Floppy Disk Power Management à Serial Port Power Management à Parallel Port Primary IDE 0 Enabled Disabled These items enable or disable the detection of IDE, floppy, serial and parallel port activities for power down state transition. Actually it detects the read/write to/from I/O or address port. 3-24 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.

[. . . ] If the parameters listed do not match the ones used to format the disk, the information on that disk will not be accessible. If the autodetected parameters displayed do not match those that used for your drive, ignore them. Type N to reject the values and enter the correct ones manually from the Standard CMOS Setup screen. 3. 12 Save & Exit Setup This function automatically saves all CMOS values before leaving Setup. 3-36 AWARD BIOS 3. 13 Exit without Saving Use this function to exit Setup without saving the CMOS value changes. Do not use this option if you want to save the new configuration. 3. 14 NCR SCSI BIOS and Drivers The NCR 53C810 SCSI BIOS resides in the same flash memory chip as the system BIOS. [. . . ]
