2-12 Chapter 2 ¯ Presentation and Installation of the CPU Since 1996, every two or three months, Intel adds new models to the Pentium CPU series. That is why the CPU market is filled with a lot of different models and brands. All CPUs have different electrical specifications. That’s why installing a CPU is becoming more and more complex. You can’t help that, because everybody wants to be able to upgrade their hardware.
Installing the Mainboard 2-13 AT Bus clock Also referred to as ISA SPEED, or AT CLOCK, or even ISA Bus clock. Ten years ago, the original specification of AT Bus clock installed in the first generation PC/AT computers was 8MHz, this means that there are some interface cards which can only work at 8MHz.
2-14 Chapter 2 P-Rating The P-Rating was defined by some manufacturers other than Intel to rate the performance of their CPU in comparison with Intel Pentium CPUs. For instance, Cyrix 6x86 P166+ has a higher actual speed compared with Intel Pentium P166, its internal clock needs only 133MHz versus 166MHz for Intel’s product. The main reason is that Cyrix has improved the internal architecture of the 6x86 CPU, which means that with the same internal clock speed, the actual clock speed will be different.

Introduction to BIOS Chapter 3 3-1 Introduction to BIOS The BIOS is a program located on a Read-Only Memory chip on the mainboard. This program will not be lost when you turn the computer off. This program is also referred to as the boot program. It is the only channel for the hardware circuit to communicate with the operating system.
3-2 Chapter 3 Three to five seconds after the message is displayed, if you press the Del key, or if you press the Ctrl Alt Esc keys simultaneously, you will access the BIOS Setup menu. At that moment, the BIOS will display the following message: Fig 3 BIOS Setup main menu In the BIOS Setup main menu of Figure 3, you can see several options.
Introduction to BIOS Computer knowldge 3-3 CMOS DATA Maybe you have heard somebody saying that their CMOS DATA was lost. What is the CMOS? Is it important? The CMOS is the memory used to store the BIOS parameters that you have configured. This memory is passive. You can read its data and you can also store data in it. But this memory has to be powered by a battery in order to avoid any loss of its data when the computer is turned off.
3-4 Chapter 3 ¬ Standard CMOS Setup Menu These are the basic configuration parameters of the BIOS. These parameters include the date, hour, VGA card, FDD and HDD settings. Fig 3-2 l Standard CMOS Setup Menu Set up of HDD operating mode ¡i NORMAL, LBA, LARGE ¡j Since old operating systems were only able to support HDDs with a capacity less than 528MB, any hard disk with more than 528MB was unusable.
Introduction to BIOS 3-5 ä LBA (Logical Block Addressing) mode: LBA mode supports hard disk drives up to 8.4Giga. This mode uses a different method to calculate the position of disk data to be accessed. It translates Cylinders (CYLS), Heads and Sectors into a logical address where data is located. The Cylinders, Heads, and Sectors displayed in this menu do not reflect the actual structure of the hard disk, they are just reference values used to calculate actual positions.
3-6 Chapter 3 - BIOS Features Setup Menu BIOS Features Setup Menu has already been set for maximum operation. If you do not really understand the options in this menu, we recommend you use default values. In each item, you can press at any time to display all the options for this item. Fig 3-3 BIOS Features Setup Virus Warning: This item can be set as Enable or Disable.
Introduction to BIOS 3-7 CPU External Cache: This item is used to enable or to disable the CPU external cache. When the external cache is enabled, the system works faster. The default is Enable. Quick power on self test: After the computer has been turned on, the BIOS of the mainboard will run a series of tests in order to check the system and its peripherals. If the Quick power on self test feature is Enable, the BIOS will simplify the test procedures in order to speed up the boot process.
3-8 Chapter 3 Boot Up Floppy Seek: When the computer boots up, the BIOS detects if the system has a FDD or not. When this item is enabled, if the BIOS does not detect a floppy drive, it will display a floppy disk drive error message. If this item is disabled, the BIOS will skip this test. Boot Up NumLock Status: ä ä On: At boot up, the Numeric Keypad is in numeric mode. Off: At boot up, the Numeric Keypad is in cursor control mode. IDE HDD Block Mode: This item can be set as Enable or Disable.
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.
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’t enable 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.
Introduction to BIOS Computer knowledge 3-11 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. If you don’t know the hardware very well, use default values (use the LOAD SETUP DEFAULTS option). Fig 3-4 Chipset Features Setup You can use the arrow keys to move between the items.
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. DRAM settings: The other DRAM settings are all closely related to hardware. If you do not understand this very well, don’t make any changes. Our BIOS is able to autodetect the characteristics of your DRAM and to choose the best settings.
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 turned on but inactive, the power consumption is reduced in order to save energy. When the computer operates normally, it is in Normal mode.
Introduction to BIOS 3-15 2. Use arrow keys to go to the item you want to configure. To change the settings, use "PgUP", "PgDn", "+" and "-". 3. 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 User Define User Define defines the delay for accessing the power modes. ä Disable Disable Power Management features.
3-16 Chapter 3 Video Off After: Select the saving mode in which the video is switched off. ä Always On The video will never be switched off in no saving mode. ä All Modes Off The video will be switched off in all saving modes. ä Standby The video will only be switched off in Standby or Suspend mode. ä Suspend The video will only be switched off in Suspend mode.
Introduction to BIOS 3-17 Suspend Mode: When the setting selected for "Power Management" is "User Define", you can set this mode for 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. The CPU stops working completely. If this mode is disabled, the system will not enter the Suspend mode.
3-18 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 Reset PnP Config Data: 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.
Introduction to BIOS 3-19 BIOS Auto-Config PCI IRQ: This option enables or disables the BIOS capability to automatically assign IRQs. The BIOS default is Disable. When you select Enable, the BIOS will automatically assign the correct IRQ to the interrupt number (INT#) of the PCI slots. When this option is disabled, you have to assign IRQs used by the interrupt number (INT#) of the PCI slots.
3-20 Chapter 3 PCI IDE Card IRQ Map to: Three options are available for this item: PCI Auto, PCI-slotX and ISA. ä PCI-Auto: The onboard BIOS auto-detects which PCI slot has an IDE card inserted in. ä PCI-slotX: Some old PCI IDE cards cannot be detected by the BIOS. If the onboard BIOS cannot detect a PCE IDE card, you have to specify on which PCI slot the IDE card is inserted, to make the BIOS assign IRQ14 for use by the interrupt number (INT#) of this PCI slot.
Introduction to BIOS 3-21 On Board FDD Controller: This is to Enable or Disable the Onboard FDD Controller. On board Serial Port 1: This is used to specify the I/O address and IRQ of Serial Port 1. Ten options are available: Disable, 3F8h/IRQ4, 2F8h/IRQ3, 3E8h/IRQ4 or 2E8h/IRQ3, 3F8/IRQ10, 2F8/IRQ11, AUTO, 3E8/IRQ10, 2E8/IRQ11. On board Serial Port 2: This is used to specify the I/O address and IRQ of Serial Port 2.
3-22 Chapter 3 / ECP Mode Use DMA: When the mode selected for the onboard parallel port is ECP, the DMA channel selected can be Channel 1 or Channel 3. / EPP Mode Select: When the mode selected for the onboard parallel port is EPP, two EPP version options are available: EPP1.7 or EPP1.9 . On board IDE-1 Controller: Onboard PCI IDE 1 controller can be set as Enable or Disable. / Master drive PIO Mode: ä Auto: the BIOS can auto-detect the PIO mode of the HDD in order to set its data transfer rate.
Introduction to BIOS 3-23 2 For further information about HDD installation, refer to Appendix E. ± Load BIOS Defaults BIOS defaults are the reference settings that allow your system to work at a comparatively low performance.

General Discussion about HDD Installation Appendix E E-1 General Discussion about HDD Installation Most recent HDDs use IDE interface. Installing an IDE hard disk does not require great intelligence like installing the driver for a SCSI hard disk, but this means that the user must install the hard disk by themselves and cope with all the problems he may encounter. Here, we will try to help you solve these possible problems.
E-2 Appendix E The higher the MODE value is, the better 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. Here are some examples of data transfer rates for IDE HDD with DMA mode: DMA Mode 0 The fastest data transfer rate reaches 4.16Mbyte/sec DMA Mode 1 The fastest data transfer rate reaches 13.
General Discussion about HDD Installation E-3 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. The Master or Slave status of the hard disk drive is set on the hard disk itself.
E-4 Appendix E Installing two HDDs: The red line on the connection cable must be lined up with pin 1 on the connector. 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 mainboard.
General Discussion about HDD Installation E-5 Installing three HDDs: The red line on the connection cable must be lined up with pin 1 on the connector. 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.
E-6 Appendix E BIOS Setup: ♦ If all your HDDs are new, you can use the IDE HDD Auto Detection option in the CMOS to autodetect the parameters of all your drives. You don’t need to set any hard disk parameter. ♦ If one or several of your HDDs are old, and if you don’t know their parameters, and you want to reconfigure your drives, you can also use the IDE HDD Auto Detection option in the CMOS to autodetect the drives parameters.
General Discussion about HDD Installation E-7 Using FORMAT: (DOS command) This command is found in the DOS disks. FORMAT is used to format the hard disk. The HDDs have to be formatted before use. Don’t forget to add /S after C:, otherwise the hard disk will not be bootable after formatting.
