BIOS - Component Information

Now we are going to talk a little about BIOS component information.
On almost all computers when you press the "Turn On" button you will wait a little and after that it will boot into your operating system. Before it boots, you will have a down-bar where you can see something like: "Press F2 to enter Setup" or "Press Esc to enter Setup" or something similar. On major manufactures you have to press F2 button to enter into BIOS, but can be different from manufacturer to manufacturer.

Ok, we are in BIOS... Here we can use the BIOS information to learn which components are installed in the computer and some of their attributes. This information can be useful when troubleshooting hardware that is not working properly and to determinate upgrade options. These are some of the common components infomartion items that are displayed in the BIOS:
1. CPU - Displays the CPU manufacturer and speed. The number of installed processors is also displayed.
2. RAM - Displays the RAM manufacturer and speed. The number of slots and which slots the RAM modules are installed in might also be displayed.
3. Hard Drive - Displays the manufacturer, size, and type of the hard drives. The type and number of hard disk controllers might also be displayed.
4. Optical Drive - Displays the manufacturer and type of optical drives.
