Auto Configuration: This option allows (Enable) or prevents (Disable) the BIOS from using default values for Auto Configuration. ä When you select Enable, the BIOS will automatically use the values related to DRAM. ä When you select Disable, you can manually set up DRAM options. Introduction to BIOS 3-13 Attention:Unless you are very familiar with your computer and with the DRAM configuration and speed, we recommend you do not change the DRAM options but enable this option. There are small differences in the chipset feature setup according to different mainboard models, but this has no influence on performance. That is why we do not describe all the features of this menu. 3-14 Chapter 3 , , Power Management Setup Menu The difference between Green PCs and traditional computers is that Green PCs have a power management feature. With this feature, when the computer is powered on but inactive, the power consumption is reduced in order to save energy. In this mode, the Power Management Program will control the access to video, parallel ports, serial ports and drives, and the operating status of the keyboard, mouse and other device. In cases where none of these events occur, the system enters the power saving mode. When one of the controlled events occurs, the system immediately returns to normal mode and operates at its maximum speed. Power saving modes can be divided into three modes according to their power consumption: Doze Mode, Standby Mode , and Suspend Mode. The four modes proceed in the following sequence: Normal Mode ===> Doze Mode ===> Standby Mode ===> Suspend Mode The system consumption is reduced according the following sequence: Normal > Doze > Standby > Suspend 1. In the Main Menu, select "Power Management Setup" and press "Enter". The following screen is displayed: Fig 3-5 Power Management Setup Menu Introduction to BIOS 3-15 2. To change the settings, use "PgUP", "PgDn", "+" and "-". After you have configured the Power Management feature, press "Esc" to go back to the Main Menu. We are now going to briefly explain the options in this menu: Power Management: Four options: ä ä User Define User Define defines the delay for accessing the power modes. Min Saving When the three saving modes are enabled, the system is set up for minimum power savings. Doze = 1 hour Standby = 1 hour Suspend = 1 hour Max Saving When the three saving modes are enabled, the system is set up for maximum power savings. Doze = 1 minute Standby = 1 minute Suspend = 1 minute ä PM Control by APM: Power Management is completely controlled by the APM. APM stands for Advanced Power Management, it is a power management standard set by Microsoft, Intel and other major manufacturers. Modem Use IRQ: If you use a modem, enter which IRQ it is using so that the APM can control it . Video Off Option: Select the saving mode in which the video is switched off. ä ä Always On The video will never be switched off in no saving mode. All Modes Off The video will be switched off in all saving modes. 3-16 ä ä Suspend or Suspend ( Susp, Stby -- > Off ) The video will only be switched off in Standby or Suspend mode. [. . . ] F If you can boot up: Insert back the interface cards you have removed one by one and try to start the system each time you insert a card, until the system does not start anymore. Keep the VGA card and the interface card that causes the problem inserted on the mainboard, remove any other card or peripheral, and start again. If you still cannot start, note down the information related to both cards in the Add On Card space provided, and don't forget to indicate the mainboard model, version, BIOS identification number, CPU (refer to main instructions), and give a description of the problem. I-2 Appendix I 2 Example 2: With a system including the mainboard (with CPU, DRAM, COAST. . . ) HDD, CD-ROM, FDD, VGA CARD, LAN CARD, MPEG CARD, SCSI CARD, SOUND CARD, after assembly and after having installed the Sound Card Driver, when you restart the system, when it runs the Sound Card Driver, it resets automatically. During the Starting DOS* procedure, press SHIFT (BY-PASS) key, to skip CONFIG. SYS and AUTOEXEC. BAT; edit CONFIG. SYS with a text editor, and in front on the line that loads the Sound Card Driver, add a remark REM, in order to disable the Sound Card Driver. [. . . ]
