User manual ABIT APTX5E

[. . . ] Foreword Foreword Thank you for purchasing the AB-PX5/AX5/TX5 as the heart of your computer' system. s We hope this instruction booklet will enable you to install PX5/AX5/TX5 in your system safely and without any errors. Although you may be familiar with some of the concepts we will explain, please read over them again to avoid any problems. 1. The motherboard in most PCs use many connecting cables to connect peripherals to the main unit. The important thing to remember is that these cables all have a ` direction' Later in the chapter, we will talk more about the definition of connecting . [. . . ] The central voltage value between 3. 45V and 3. 6V is 3. 52V. Introduction of BIOS 3-9 Attention: After setting up the parameters and you leave the BIOS SETUP, and you have verified that the system can be booted, do not press the Reset button or turn off the power supply. Otherwise the BIOS will not read correctly, the parameters will fail and you must enter CPU SOFT MENUTM again to set up the parameters all over again. 3-10 Chapter 3 - Standard CMOS Setup Menu It is the basic configuration parameters of the BIOS. These parameters include the settings of date, hour, VGA card, FDD and HDD. Fig 3-2 Standard CMOS Setup Menu l Set up of HDD operating mode ¡i NORMAL, LBA, LARGE ¡j Since old operating systems were only able to support HDD whose capacity was not bigger than 528MB, any hard disk with more than 528MB was unusable. AWARD BIOS features a solution to this problem: you can, according to your operating system, choose three operating modes: NORMAL, LBA or LARGE. ä Normal mode: Standard normal mode supports hard disks of 528MB or less. This mode directly uses positions indicated by Cylinders (CYLS), Heads, and Sectors to access data. Introduction of BIOS 3-11 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 are 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. Currently, all high capacity hard disks support this mode, that' why we recommend you s use this mode. The HDD AUTODETECTION option in the Main Menu will automatically detect the parameters of your hard disk and the mode supported. ä LARGE Mode: When the number of cylinders (CYLs) of the hard disk exceeds 1024 and DOS is not able to support it, or if your operating system does not support LBA mode, you should select this mode. l FDD supporting 3 Mode: 3 Mode floppy disk drives (FDD) are 3 1/2" drives used in Japanese computer systems. If you need to access data stored in this kind of floppy, you must select this mode, and of course you must have a 3 Mode floppy drive. 2 For further information about HDD installation, refer to Appendix E. 3-12 Chapter 3 ® BIOS Features Setup Menu BIOS Features Setup Menu has already been set for maximum operation. If you do not really understand each of the options in this menu, we recommend you use default values. In each item, you can press <F1> 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. When this feature is enabled, if there is any attempt from a software or an application to access the boot sector or the partition table, the BIOS will warn you that a boot virus is attempting to access to the hard disk. CPU Internal Cache: This item is used to Enable or to Disable the CPU internal cache. When the cache is set at Disable, it is much slower, so the default setting for this item is Enable. Some old and very bad programs will make the computer malfunction or crash if the system speed is to high. In that case, you should Disable this feature. Introduction of BIOS 3-13 CPU External Cache: This item is used to enable or to disable the CPU external cache. The default is Enable. Quick power on self test: After the computer has been powered 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.
