Foreword
Thank you for purchasing the AB-PX5/AX5/TX5 as the heart of your computer' s system.
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
cables and the method of installation. Please pay special attention to our prompts.
Because we are using the exclusive ABIT SOFTMENU technology to modify the
motherboard , the jumper is not required anymore. We also use simple and easy to
understand software design to complete this task. Because of this, you can install
the motherboard directly into the system. However, we still suggest you first carry
out a simple test before you install the motherboard inside the computer.
2. In this booklet, we will write out in full any new technical words we encounter for
the first time and use their contractions thereafter.
3. If, when you are installing the CPU problems occur and there is no way to solve
them, we suggest you first clear the CMOS information (refer to Chapter 2). If you
still have problems, contact us.
4. How to perform a simple basic test? It' s simple. Place the mother board on a flat
insulated surface (like the packaging the motherboard came in). Plug the CPU into

  • Page 93 General Discussion about HDD Installation Appendix E General Discussion about HDD Installation Most of the present HDDs use IDE interface. Installing an IDE hard disk does not require a huge amount of intelligence like installing the driver for a SCSI hard disk, but this means that the user often must install the hard disk by himself and cope with all the problems he may encounter.
  • Page 94 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 95 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.
