[. . . ] (Unit: characters/second ¡^ Typematic Rate Delay (Msec): When you press a key continuously, if you exceed the delay you have set here, the keyboard will automatically repeat the keystroke according to a certain rate. (Unit: milliseconds) Introduction to BIOS 3-9 Security Option: This option can be set to System or to Setup. After you have created a password through PASSWORD SETTING, this option will deny access to your system (System) or modification of the computer setup (BIOS Setup) by unauthorized users. ä SYSTEM: When you choose System, a password is required each time the computer boots up. If the correct password is not given, the system will not start. ä SETUP: When you choose Setup, a password is required only when accessing the BIOS Setup. If you have not set a password in the PASSWORD SETTING option, this option is not available. If you forget the password, t you will have to open the computer case and clear all information in the CMOS before you can start up the system. But doing this, you have to reset all the options you had set up before. PCI /VGA Palette Snoop: This option allows the BIOS to preview VGA Status, and to modify the information delivered from the Feature Connector of the VGA card to the MPEG Card. This option can solve the display inversion to black after you have used the MPEG card. Delay IDE Initial: This item is used for supporting some older models or special types of hard disks or CDROMs, since the BIOS may not detect those kinds of devices during system booting . OS Select For DRAM > 64MB: When the system memory is larger than 64MB, the communication method between the BIOS and the operating system will differ from one operating system to another. If you use OS/2, select OS2; if you choose another operating system, select Non-OS2. Video BIOS Shadow: This option is used to define whether the BIOS on the video card uses shadow feature or not. You should set this option to Enable, otherwise the display performance of the system will be greatly decreased. 3-10 Chapter 3 Shadowing address ranges (C8000-CBFFF Shadow): This option allows you to decide if the memory block (BIOS) of an interface card at the address C8000-CBFFF uses the shadow feature or not. If you do not have an interface card using this memory block, don' enable t this option. Shadowing address ranges (CC000-CFFFF Shadow): This option allows you to decide if the memory block (BIOS) of an interface card at the address CC000-CFFFF uses the shadow feature or not. If you do not have an interface card using this memory block, don' enable t this option. Shadowing address ranges (D0000-D3FFF Shadow): This option allows you to decide if the memory block (BIOS) of an interface card at the address D0000-D3FFF uses the shadow feature or not. If you have do not have an interface card using this memory block, don' t enable this option. Shadowing address ranges (D4000-D7FFF Shadow): This option allows you to decide if the memory block (BIOS) of an interface card at the address D4000-D7FFF uses the shadow feature or not. If you do not have an interface card using this memory block, don' enable t this option. Shadowing address ranges (D8000-DBFFF Shadow): This option allows you to decide if the memory block (BIOS) of an interface card at the address D8000-DBFFF uses the shadow feature or not. If you do not have an interface card using this memory block, don' enable t this option. Shadowing address ranges (DC000-DFFFF Shadow): This option allows you to decide if the memory block (BIOS) of an interface card at the address DC000-DFFFF uses the shadow feature or not. If you do not have an interface card using this memory block, don' enable t this option. Introduction to BIOS 3-11 Computer knowledge SHADOW What is a SHADOW?The BIOS of standard video or interface cards is stored in ROM, and it is often very slow. With the Shadow feature, the CPU reads the BIOS on the VGA card and copies it into RAM. When the CPU runs this BIOS, the operation is speeded up. 3-12 Chapter 3 ® Chipset Features Setup Menu The Chipset Features Setup Menu is used to modify the contents of the buffers in the chipset on the mainboard. Since the parameters of the buffers are closely related to hardware, if the setup is incorrect, the mainboard will become unstable or you will not be able to boot up. [. . . ] CPU: Indicate the brand and the speed (MHz) of your CPU. Example: (A) In the "Brand" space, write "Intel", in the "Specifications" space, write "150MHz"¡C (B) In the "Brand" space, write "Cyrix", in the "Specifications" space, write "P166+"¡C (C) In the "Brand" space, write "AMD", in the "Specifications" space, write "P75". 7. HDD: Indicate the brand and specifications of your HDD(s), specify if the HDD is using ¨IDE1 or ¨IDE2. If you know the disk capacity, indicate it and check ("ü") " "; in case you give no indication, we will consider that your HDD is "þIDE1" Master. Example: In the "HDD" space, check the box, in the Brand space, write "Seagate", in the Specifications space, write "ST31621A (1. 6GB)". 8. [. . . ]
