  • Page 38: Cpu Setup

    Chapter 3 (1) CPU setup<CPU SOFT MENU™> The CPU can be setup through a programmable switch (CPU SOFT MENU™), that replaces traditional manual hardware configuration. This feature allows the user to complete more easily the installation procedures. You can install the CPU without configurating any jumpers or switches. The CPU must be setup according its specifications.
  • Page 39 Introduction of BIOS CPU Operating Speed: This option sets the CPU speed. Different CPU brands use different techniques to indicate the CPU speed. For example, AMD and Cyrix use P-Rating. In this field, the CPU speed is indicated like this: CPU speed (external clock x multiplier factor) Select the CPU speed according the type and the speed of your CPU.
  • Page 40 Chapter 3 Normally, we do not recommend that you use the “User Define” option to setup CPU speed and multiplier factor. This option is for setup of future CPUs whose specifications are still unknown. The specifications of all present CPUs are included in the default settings. Unless you are very familiar with all CPU parameters, it is very easy to make mistakes when you define by yourself the external clock and the multiplier factor.
  • Page 41 Introduction of BIOS Method 1: Setup up the CPU for the lowest speed for its brand. Turn the power supply off and change the CPU. Then turn the system on again, and set up the CPU parameters through CPU SOFT MENU. Method 2: Try turning the system on a few times (3~4 times) and the system will automatically use its standard parameters to boot.

If you have no interface card using this memory block, don’ t enable this option.
  • Page 51 Introduction of BIOS 3-17 What is the 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.

  • Page 86 Appendix E The higher the MODE value is, the best is the hard disk data transfer rate. But this does not mean that you can select the highest mode value as you like. You must be sure that your hard disk supports that type of fast data transfer, otherwise your hard disk will not be able to operate correctly.
  • Page 87 General Discussion about HDD Installation Installing a hard disk: In the Standard CMOS Setup Menu, Primary means the first connector on the mainboard, that is, connector IDE1 on our mainboard. Secondary means the second connector on the mainboard, that is, connector IDE2 on our mainboard. Two HDDs can be connected to the each connector: The first HDD is referred to as Master, The second HDD is referred to as Slave.

Method 1: Set the hard disk drive used for boot up at Master, and the other drive at Slave. Connect one of the connectors of the 40-pin cable to the first drive, another connector to the second drive, and the other end of the cable to connector IDE1 on the...

Method 1: Set the hard disk drive used for boot up at Master, set the second drive at Slave. Connect one connector of the 40-pin cable to the first drive, another connector to the second drive, and the other end of the cable to connector IDE1 on the mainboard.
  • Page 90 Appendix E If one or several of your HDD are old, and if you don’ t want to erase the data stored in your drives, you will have to remember the parameters (Type, Cylinders, Heads, Sectors, Mode) of the drive(s) you don’ t want to erase. After you have used the IDE HDD Auto Detection option in the CMOS, enter the Standard CMOS Setup Menu to change the settings of the related hard disk drive.
