[. . . ] APM stands for Advanced Power Mangement, it is a power management standard set by Microsoft, Intel and other major manufacturers. Video Off Method: Three video off methods are available: "Blank", "V/H SYNC+Blank" and "DPMS". If this setting does not shut off the screen, select "Blank". If your monitor and video card support DMPS standard, select "DPMS". Introduction of BIOS 3-19 Video Off After: Select the saving mode in which the video is switched off. ä ä ä ä NA The video will never be switched off in no saving mode. Standby The video will only be switched off in Standby or Suspend mode. Suspend The video will only be switched off in Suspend mode. IDE HDD Power Down: If the system has not accessed data on the hard disk drive during the specified time period, the engine of the HDD will stop in order to save electricity. You can set 1 to 15 minutes or select Disable according to your use of the HDD. Doze Mode: When the setting selected for "Power Management" is "User Define", you can define for this mode any delay from 1 minute to 1 hour. If no power management event occurs during this time period, meaning that computer is inactive during this period, the system will enter the Doze power saving mode. If this mode is disabled, the system will enter the next mode in the sequence (Standby or Suspend mode). Standby Mode: When the setting selected for "Power Management" is "User Define", you can define for this mode any delay from 1 minute to 1 hour. If no power management event occurs during this time period, meaning the computer is inactive during this period, the system will enter the Standby power saving mode. If this mode is disabled, the system will enter the next mode in the sequence (Suspend mode). 3-20 Chapter 3 Suspend Mode: When the setting selected for "Power Management" is "User Define", you can define for this mode any delay from 1 minute to 1 hour. If no power management event occurs during this time period, meaning the computer is inactive during this period, the system will enter the Suspend power saving mode. If this mode is disabled, the system will not enter the Suspend mode. Throttle Duty Cycle: This is used to specify the CPU speed in saving mode. Seven options are available: 12. 5%, 25. 0%, 37. 5%, 50. 0%, 62. 5% or 75. 0% . CPU Fan Off In Option: CPU fan can be turn off in suspend mode. Power Button Override: Support ACPI Power Button Over-ride. The user presses the power button for more then four seconds while the system is in the working state, then the system will transition to the soft-off(Power off by software). This is called the power button over-ride. IRQ8 Break Suspend : Support RTC alarm wake up from suspend function (via IRQ8). Reload Global Timer Events When one of the speficied occurs, the count down made for entry in power saving mode goes back to zero. Since the computer will enter a power saving mode only after an inactivity delay specified (time speficied for Doze, Standby and Suspend modes) and after it has no activity, during this time period, any event will cause the computer to re-count the time elapsed. Resume events are operations or signals that cause the computer to resume time counting. Resume by Ring: To connect a external modem with the onboard serial port, the system will be turned on when telephone ring-up. Introduction of BIOS 3-21 Resume by Alarm : RTC alarm can turn on the system . You can set date ( of month ) and time ( hour , minute , second ) . 3-22 Chapter 3 ± PCI & Onboard I/O Setup In this menu, you can change the INT# and IRQ of the PCI bus and the onboard I/O device, I/O port address and other hardware settings. Fig 3-6 PCI & Onboard I/O Setup PnP OS Install : Device resource assigned by PnP OS or BIOS. Force Update ESCD: If you want to clear ESCD data next time you boot up, and ask the BIOS to reset the settings for the Plug & Play ISA Card and the PCI Card, select Enabled. But the next time you boot up, this option will automatically be set as Disabled. ESCD (Extended System Configuration Data) The ESCD contains the IRQ, DMA, I/O Port, Memory information of the system. This is a specification and a feature specific to Plug & Play BIOS. Computer Knowledge Introduction of BIOS 3-23 Resources Controlled By: When you select Auto, the BIOS will automatically assign the IRQ and DMA to PCI / ISA PnP . [. . . ] Or, in the Brand space, write "SEC", in the Specifications space, write "DIMM-S DRAM 8MB-G12". 10. COAST: Indicate the brand and specifications of your COAST. Example: In the Brand space, write "Winbond", in the Specifications space, write "256KB" or "W25P010AF-8"¡C 11. ADD-ON CARD: Indicate which add-on cards you are "absolutely sure" are related to the problem. If you cannot identify the problem origin, indicate all the add-on cards inserted into your system. Note: Items between the "*" are absolutely necessary.
