Find out what kind socket your motherboard has. 
Do a Google search if your current motherboard model supports a newer processor.Find out also if your motherboard is a 32-bit or a 64-bit one. The major sockets are:

Socket 370: Intel Pentium III, Celeron.
Socket 462 (socket A): AMD Athlon, Duron, Athlon XP, Athlon XP-M, Athlon MP, Sempron.
Socket 423: Pentium 4.
Socket 478: Intel Pentium 4, Celeron, Pentium 4 Extreme Edition.
Socket 479 (mobile): Intel Pentium M, Celeron M, Core Solo, Core Duo.
Socket 754: AMD Athlon 64, Sempron, Turion 64.
Socket 775: Intel Pentium D, Pentium 4, Celeron D, Pentium Extreme Edition, Hyper treading, Core 2 Duo, Core 2 Quad.
Socket 1156: Intel Core i3, Core i5, Core i7.

Socket AM3+: AMD FX X4, X6, X8
Socket FM1: AMD Llano APU X2, x3, X4

Replacing the Processor 
Take out your old CPU. Open up your case, unclip the Heatsink off the retaining board, and pull the the heatsink off. Some heatsinks require a screwdriver or other proprietary tool to remove.

Open the lever on the side of the socket. Do this by pulling it out, and then pulling it up. Gently lift your old CPU off of the socket.

Take the new CPU out of the box. Line up the gold triangle on the CPU with the one on the socket, and gently let the CPU fall in place. Do not force the CPU. If it is lined up correctly, it will drop right into place.

Close the ZIF (zero insertion force) lever to lock the CPU. Take the included heatsink and clip it on using the instructions. If your heatsink doesn't have thermal paste* or pads on it yet, apply a very thin layer of it. The thermal paste acts as a conductor, transferring the heat from the processor chip to the heat sink. If the heatsink includes a fan, plug it into its proper connector. Do not operate a CPU without thermal transfer material or a heatsink in place.


*Thermal paste is very toxic, you have too wash your hands after using it.

Windows 7 was not supported and the IDE driver refused to install.
But when it was extracted from a setup file to a folder, the device manager has found in that folder wat was needed.

BIOS upgrade

You may need to flash (update) BIOS to support new technology such as dual core or Hyper threading.(Page 3)

Find the manufacturer of the BIOS chip And see if you can download. a newer BIOS firmware .
There are two types of upgrades .
The inf BIOS so that you can flash from within Windows.

Or you have to create a floppy disk.
HP (Compaq) goes as follows.
Search for a BIOS that is offered for that model number
A BIOS has nothing to do with your Operating System
If you cannot find the file in the Windows 7 section then search for that file in the XP section.
Download the latest BIOS firmware.
That could be a setup file where you can click on directly or a ZIP file that has to unpack first.
If you click on it, then it creates on C:\ a separate folder SWsetup and puts those data there.
It seems that it is installed, but that is not true.
That unpack in SW Setup will also happens with other downloads like Video and Audio
Then you have to go to that folder to click on the setup file.
In this case, that file will unpack itself on a floppy disk.
When there is no floppy disk in the computer, use an external USB floppy disk.
Be sure that the Floppy can be found and will start first in you‘re old BIOS
If the floppy is ready then start your computer first with a MS DOS disk.
On your Lesson DVD you can find the file that creates a bootable DOS floppy.

Start the computer with the DOS floppy
It seems that the computer is going BANANA(S)
But that is a typical nerd joke.

Than you see A:\
Put the BIOS floppy into the computer and type; dir
Then you see the contents of that floppy.
Look for a flash file with .Exe or .Bat (
executable batch file)


Type the file name and follow the instructions.
Take the floppy out and reboot with ctrl, alt, delete.

(officially Hyper-Threading Technology or HT Technology, abbreviated HTT or HT) is Intel's proprietary simultaneous multithreading (SMT) implementation used to improve parallelization of computations (doing multiple tasks at once) performed on PC microprocessors. It first appeared in February 2002 on Xeon server processors and in November 2002 on Pentium 4 desktop CPUs. Later, Intel included this technology in Itanium, Atom, and Core 'i' Series CPUs, among others.

For each processor core that is physically present, the operating system addresses two virtual or logical cores, and shares the workload between them when possible. The main function of hyper-threading is to decrease the number of dependent instructions on the pipeline. It takes advantage of superscalar architecture (multiple instructions operating on separate data in parallel). They appear to the OS as two processors, thus the OS can schedule two processes at once. In addition two or more processes can use the same resources. If one process fails then the resources can be readily re-allocated.

Hyper-threading requires not only that the operating system supports SMT, but also that it be specifically optimized for HTT, and Intel recommends disabling HTT when using operating systems that have not been optimized for this chip feature.
