If Windows is the friendly face that displayed projects to the world's computers, the BIOS is the dark side of the subconscious in charge to think. BIOS (Basic Input / Output System) is a code for the fundamental functions of a PC, such as collecting beats from a keyboard button or put pixel to screen.
This small program works behind the scenes, translating the Windows command that people be zero-friendly and one that is only understood by your hardware. And as the human subconscious, the BIOS can be very strong influence on the behavior and performance of your PC.
BIOS Therapy
As new technologies emerge and old bugs are found, computer makers often issue that has been updated BIOS version which can solve problems and improve performance. Check the Web site PC makers about the latest updates. But first make sure you have the latest BIOS version number; usually appears briefly on your monitor right after you turn on the system. (Press the Pause button when kilasannya too fast.)
Updating the BIOS is easy, but you must do so with caution. Usually you need to run a small program from a floppy disk only. But when problems occur, you can only lament the motherboard that can no longer use. So make sure that you have read all the instructions in the readme file updated BIOS. And always do exactly what the clues were saying.
If the BIOS is subconscious PC, the Setup utility is the foundation for building character PC. The utility has a user settings to control the hard disk, memory, graphics cards, power saving, USB ports, and other hardware. The program is usually included in the disk, but are now already stored in the same chip with the BIOS ROM PC.
To open the setup, just press the button (or key combination) is recommended to you to be included when the PC starts up. Each BIOS manufacturer uses a different key - Delete, F1 or F10. On your screen should show the buttons or keys which need to be pressured to setup right after the screen displays the BIOS version number. If not, check your system documentation.
Because the Setup utility created by the BIOS maker and be in the same chip with the BIOS, it is often called the BIOS Setup utility. And since this utility to save the settings under the chip clock / calendar - chip complementary metal-oxide semiconductor, or CMOS - then often referred to as the CMOS Setup program. (CMOS chip has its own battery to maintain settings even when the PC chip is turned off.)
The Setup utility has an abundance of hardware settings, ranging from the obvious, like setting the clock time on a PC, up to the invisible, like the amount of "wait states" that coordinate the flow of data between RAM and CPU.
First, Do not Ruin
When working with PC Setup utility, use the same rule of thumb taught in early brain surgery: If you do not know what to do something, do not deal with it. Carelessness change wait state or other settings can degrade performance or even cause system crashes.
If you think you've accidentally changing settings while working with the Setup utility, immediately stop and start from scratch again. All Setup utility has a menu option that lets you exit without saving changes. You may see also the option to restore settings to default values. Ignore this option: If your PC vendor has been doing fine-tune the system, the creator of the BIOS default settings may make it not optimal.
Backup your settings before making changes. When the battery feed chip clock / calendar to death, the settings you die with him. When the Setup utility you have a backup option, use it. If not, record the settings in the paper - or press the Print Screen key to each screen in these utilities (but this does not always work).
What's Wanted
Before you begin, read through the user manual that came with your PC or motherboard. Many manuals offer a brief explanation of each setting. Settings vary according to the manufacturer and model, but you should find this on almost all PCs:
Optimization and compatibility settings: Setup utility often contain settings for hardware performance. Sometimes this is not set optimally at the factory, mainly based on the PC that made the order or generic. Scan all the Setup program. Setting AGP mode and setting the DMA is the leading candidate to be optimized. These settings are also useful for troubleshooting new hardware is installed: Disable or reduce a given setting can trigger non-kompatibelan graphics card, CD-ROM drive, or other devices that happen before.
Setting hard drive: You'll find a table, usually on the second page or the Advanced and under the title "IDE", which lists all the configuration parameters for EIDE hard drives that are directly connected to the motherboard. (SCSI and EIDE hard disk drive that has no expansion card will run the program their own configuration.) While most PCs are made during the last few years can seamlessly detect and configure a new hard drive, most memerlukan manual installation. Read your new disk documentation about these procedures and use the options on-screen to make changes in this table.
Floppy disk: This option lets you set the type of floppy drives (3.5 inch, 1.44 MB, for example) that you assigned as drive A: or B: you. This is a setting that needs to be checked if you experience a problem floppy-drive. Some Setup Utilities have security settings Floppy `own` Read-only prevents your data written to a floppy disk and deleted from your PC.
Boot sequence: This setting determines where the first times when the PC boot-up instructions. Example: `A: then C:`, `C: then A:`, or `C:,` Zip drives. To boot from the CD-ROM drive, Zip, or LS-120, you seem to have to change this setting.
Password protection: When this is enabled, the BIOS will ask for a password before booting up. Very careful with this one: When you forget the password, you have to reset the motherboard jumpers or removing the CMOS battery, which will cause you to lose all the settings, or you even have to buy a new motherboard.
Setting IRQ: When you need extra IRQ settings for the new hardware, you need to free up one IRQ by disabling unused features, such as serial ports, parallel port, or USB port.
Parallel port settings: Select the most suitable mode for hardware. ECP or EPP mode can greatly speed up printers and other devices.
CPU temperature and fan RPM: Two critical parameters should be checked periodically to ensure they are functioning correctly.
Hardware Help Offline Internet is great for finding answers to the questions of hardware, but investigating the Web sites for advice that could be trusted enough to spend time. Sometimes the fastest way to get answers is old-fashioned way: with a good reference book. Below are two of the best.
