Presentation And Installation Of The Cpu - Abit IT5 Series User Manual

Installing the Mainboard
® Presentation and Installation of the CPU
Jumperless Mainboard (Mainboard with no DIP Switch or Jumper)
This mainboard series can be installed with CPU without the hardware
setting of the CPU.
On other boards, when you want to install the CPU, you have, more or
less, to setup some jumpers or DIP switches. With this mainboard, you will not
need to adjust any jumper or switch. The CPU speed and model is set up by
software, in order to allow the user to complete setup and installation
procedures easily. After you have inserted the CPU on the CPU socket, you
can close the computer case and turn the computer on. You just need to enter
the CPU SOFT MENU™ located in the BIOS Setup, and to setup the speed
and the voltage of the CPU to compete the installation. Even if you don' t need to
setup any switch, we recommend you to read our presentation of the CPUs, it
will be useful information for you.
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 its hardware. So, you have to
take a bit of time to read this section, in order to be able to install a cheaper and
better processor.
This mainboard does not only support all the CPUs listed in the
specifications, but also has reserved several circuits in order to be able to
support future processors. But before we go further in our presentation, we
must clarify that "we have only tested the CPUs listed in Chapter 1", we cannot
guarantee that this board will be able to support future products, because we
cannot forecast future developments. But we will do our best to support any
possible CPU.
