bios

If Windows is the friendly face who presented 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 the keyboard button or put pixel to screen.

This small program works behind the scenes, translating the Windows command-friendly people into numbers zero and one which is only understood by your hardware. And as the human subconscious, the BIOS can be a very strong influence on behavior and performance of your PC.

Therapy BIOS

As new technologies emerge and old bug is found, computer makers often published version has been updated BIOS that 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 screen 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 if there are problems, you can only mourn the motherboard that you can no longer use. So make sure that you have read all the instructions in the readme file BIOS update. And always do exactly what the instructions say.

If the BIOS is a PC unconscious, then the Setup utility is the foundation for building character PC. Utility has a user setting to control the hard disk, memory, graphics cards, power saving, USB ports, and other hardware. The program is usually included in the disk, but now it is stored in the same chip ROM with the PC BIOS.

To open the setup, simply press the button (or key combination) is recommended to you for inclusion as a PC to start up. Each BIOS manufacturer uses a different key - Delete, F1, or F10. On your screen should show the buttons or knobs which need to setup the right button after the screen displays the BIOS version number. If not, check your system documentation.

Because the Setup utility created by the BIOS manufacturer and are in the same chip with the BIOS, it is often called the BIOS Setup utility. And because of this utility in the chip storing settingnya clock / calendar - chip complementary metal-oxide semiconductor, or CMOS - it is sometimes referred to as the CMOS Setup program. (Chip CMOS have their own batteries to maintain even a PC chip set is turned off.)

Setup utility has an abundance of hardware settings, ranging from the obvious, like setting the clock time on a PC, to the invisible, like a number of "wait states" which coordinates 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 him. 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 utilities Setup menu choice that lets you exit without saving changes. You may see also the option to restore the settings to default values. Ignore this option: If your PC vendor has been doing fine-tune the system, the default settings of the BIOS manufacturer may make it not optimal.

Backup your settings before making changes. When the battery feed chip clock / calendar to die, your settings to die with him. If you have a setup utility backup option, use it. If not, record the settings in the paper - or press the Print Screen key for each screen in these utilities (but this does not always work).

What Wanted

Before you begin, read to the end 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 Utilities often contain settings for hardware performance. Sometimes this is not an optimal set at the factory, mainly on the PC are made by order or generic. Scan the entire Setup program. AGP mode settings and DMA settings are prime candidates for optimized. These settings are also useful for troubleshooting new hardware installed: Disabling or lowering the settings provided can trigger kompatibelan lack of 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 Advanced, and under the title "IDE", which lists all the configuration parameters for EIDE hard drives are directly connected to the motherboard. (SCSI and EIDE hard disk drive that has no expansion card will run the configuration program itself.) While most PCs are made over the last few years can seamlessly detect and configure a new hard disk, some require 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 have specified as drive A: or B: you. This is a setting that needs to be checked if you have a floppy-drive problems. Some utilities have setup the security settings `Floppy Read only` in itself prevent your data is written to the floppy disk and deleted from your PC.

Boot sequence: This setting determines where the first views the PC as boot-up instructions. Example: `A: then C:`, `C: and D:`, or `C:,` Zip drive. To boot from the CD-ROM drive, Zip, or LS-120, you seem to have to change this setting.

Password protection: If this is enabled, the BIOS will ask for a password before booting up. So be careful with this one: If 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: If you need extra IRQ settings for the new hardware, you need to free the IRQ by disabling unused features, such as serial ports, parallel port, or USB port.

Parallel port settings: Select the most appropriate mode for the hardware. ECP or EPP mode can greatly speed up the printers and other devices.

Fan RPM and temperature of the CPU: Two critical parameters should be checked periodically to ensure they function properly.

Help Hardware Offline
Internet is great for finding answers to the questions of hardware, but investigating the Web sites for advice that can be trusted enough to spend time. Sometimes the fastest way to get an answer is old-fashioned way: with a good reference book. Below are two of the best.

Problem vote

Generally sound 'beep' will come out every time the computer to process or the process of booting up the computer before finally successful entry into the operating systems that sit in the komupter us.

But you know that sound 'beep' is not created without reason. try to see you, how many types of beep sound that you hear out of your computer?

For a troubleshooter (citation to analyze a problem on a computer) 'beep' on the computer is a tool that is useful in analyzing a problem. This type of analysis called analysis of voice, will usually be very helpful in knowing with certainty about the failure masalah2 booting process on the computer.

There are several types of 'beep' on the computer every so often we hear, are:

1. The sound of 'beep' 1 short time, indicates that your computer has been successfully conducted and all the components needed for the boot-up computer. If noise is heard, but also your PC is not on, you try to check your VGA cable, if installed correctly or not, or try to check your monitor, if your monitor is functioning properly or not. Conversely, if the computer works on, but no sound 'beep' ... before you try to check internal speaker on your motherboard, or check the motherboard or if necessary, please check your settings in the bios.

2. The sound of 'beep' 2 times shorter, meaning that there is a problem in the configuration or settings in the CMOS.

3. The sound of 'beep' long and short times 1 times 1, meaning there is a problem in the hardware or memory your motherboard, try to re-check that both devices are still able to function / installed properly or not.

4. Beep beep 1 long and short time 2 time, meaning there is a problem on the monitor or VGA Card.

5. The sound of 'beep' the length of time 1 and 3 times shorter, meaning that there is a problem on the keyboard, try to check your keyboard, or try to tighten the connection cable from the keyboard that is usually connected to the serial port, ps2 or usb.

6. The sound of 'beep' long and 1 short times 9 times, this means there is a problem in the ROM BIOS.

7. The sound of 'beep' long ongoing, meaning there is a problem in the DRAM.

8. The sound of 'beep' of ongoing, meaning there is a problem acceptance voltage (power).

9. In some brand motherboard issue akan sound 'beep' several times when processornya temperature is too high (hot).

Note: The sound of beep code above apply to the AWARD BIOS, the BIOS for the possibility that other code has a different beep sound.

Problem video Problems with the monitor

Analysis & solutions:
1. See the indicator light
2. Check the contrast and brightnes
3. See self test on the display screen
4. Perikasa power cable on the monitor
5. Perikasa cable data cable connection on the video out port and the display adapter
Other causes:
1. Damage display adapter card (sounds normal: BIP & sound ... there is a problem: bip4x)
2. Memory / RAM

Analysis & solutions:
1. Check the hardware and software display adapter
2. Setting resolution display adapter with a restart in safe mode with a press F8, right click desktop select properties and select the settings tab. Setting down the tabs on the display resolution and select Apply - OK.

Problem on Disk (Data Storage Media)

Problem:
Hard disk failure
After Power On self test, the BIOS melaporka message kesalahan'harddisk failure "After that the process of booting koputer and failed to stop the system

Solutions:
• check whether the BIOS setup can still be hard to detect
• If check disk is not recognized before the connection cable connection that is hard in the casing may have a loose or does not stick properly.
• If the disk is still not known to consult with experts oramg the hard disk.

Problem in Memory

This causes Windows to detect the less RAM than the previous:
1. "Damage" physical ". To overcome this you must check the condition of the physical RAM. Open your computer case, and pull the RAM is. Clean RAM and when socketnya dirty. Check also whether there is rust. You must also ensure that the RAM is of the same (golden or silvery). If different, you should replace the RAM.
2. ROM BIOS Shadowing On some 16 bit drivers and, sometimes wearing some (read: little) RAM before Windows is started. There are also some BIOS ROM shadowing feature that will copy the contents of system and video BIOS ROM to RAM in order to improve the performance of your computer (On DOS and Windows 3.1). This is because the ROM speed is lower than the RAM. But if you're using Windows 95/98/NT with minimal memory that should feature ROM shadowing off course (from the CMOS setup), for Windows 95/98/NT rarely access the ROM so that RAM can be used by Windows.
3. Use VGA card on board. If for example you have 32 Mb RAM and 2 MB VGA card, the RAM that can be used only as much as 30 Mb (32 Mb - 2 Mb). So should not the VGA card on board.
4. There is a driver or program that is run from autoexec.bat or config.sys that work using the RAM. The solution: Edit autoexec.bat and config.sys file using Notepad. Then edit the line that "suspicious" or that some are used to load the program. When you add the word REM met (but when you add the word REM program is not akan di-load/dijalankan). When you use the driver CD-ROM 4x from Teac, change the parameters xmssize = -1 in the autoexec.bat into xmssize = 0.
5. Virtual device driver running from system.ini. To overcome this open system with the click Start - Run - type sysedit. Select system.ini. Then edit the line which approximately is used to load virtual device driver. Other alternative is to create a new file system.ini.
6. There is a line on Maxphyspage Please see the system.ini file in the system.ini file, whether there is a line Maxphyspage or not. If so, delete the line.
7. Error in the CMOS settings. On some computers there is a feature Memory Hole at 16 Mb or Hold to 15 Mb RAM. If the feature is enable the RAM if you have a greater than 15 Mb or 16 Mb, Windows will detect as much as 15 Mb or 16 Mb. To overcome this, please disable the feature is.
8. Ramdrive.sys load from config.sys Check your Config.sys file for a line containing "Ramdrive.sys." If you have this line, it means you are using a RAM drive. To disable the RAM drive, remove or disable the line in the Config.sys file that contains "ramdrive.sys." To disable the line, use a text editor (such as Notepad) to edit the Config.sys file and place a semicolon (;) at the beginning of the line. Open the config.sys file with Notepad. Check on the file, whether there is a line ramdrive.sys. If so, delete the line
Why errors occur after I install new RAM?
You can look at a manual booknya. For some of the BIOS: If you install (for example) 2-4 Mb 2-8 Mb Simms and Simms, you have to put more RAM in Bank 1.
After I install new RAM, why frequent Blue Screen?
On computers that use the bus 66 MHz (Pentium 133 or higher), RAM is required with a speed of 60 ns or higher. You can only use RAM with a speed that is less than 60 ns, but you must change the settings in the BIOS Wait State. Change the setting from 0 (zero) to 1 (one).
After adding RAM, the RAM is detected still the same? After you install the RAM, you have to reset the BIOS Setup. How, at the first turn on the computer until the BIOS logo appears, press Del (for some machines may be Ctrl + Alt + Del key combination or another). When finished, select Save Settings and Exit. For additional information on these settings, you can read in the manul booknya.
Why am I seeing any posts parity Check Error?
Posts parity error check can show if there is damage in one of the RAM, one of the DMA is not running smoothly, or that there is parity boot virus on your hard disk.

Problem in the Processor / CPU

Problem:
Place the new processor but not terdeteksi.Tetepi at the time of booting the first time, the CPU speed that does not appear in the BIOS with the default number is a new processor.



Solutions:
If at the time of booting pertamakalisetelah replace the processor, the CPU speed shown in the BIOS does not like the default processor angkka new langkahpengecekan then do the following:
~ Check again if the CPU is installed correctly.
~ If the CPU is installed correctly, but is still not detected dangan well, try to check the settings motherboard.Apakah-jumpers jumpers that have been installed correctly?
~ Be careful for this step. At least you have to understand the exact position of the CPU dangan learn manual prosesor.Jika engineers need to call or the more experienced to assist you.

Problem when running computer

Problem:
Computer hangs frequently
Booting the computer can be well used and normal.tetapi time work, often experience computer hangs and the jammed-tiba.Kondisi arrived at the hang-macam.Mulai any variety of programs that do not want to run, the mouse can not be driven Keyboard does not work, until appear blue screen.hal is of course very possible because the work is often forgotten because lost data stored on the work.
Solutions:
Many things can happen and cause the computer seringmacet or hang.Tetapi the outline, which often cause the computer hangs because the software crashes and hangs caused because the hardware crash.Jika computer often hangs due to software crash, trying to do things following:
 Press the key combination [ctrl + [alt] + [del] bersamaan.bila the close program dialog box appears, then there will be some programs that have active information 'not responding' program that is causing the computer hangs.
 Click on the program hangs, then click "end task" to shut the program tersebut.tutup also programs that do not need to.
 If the computer still hangs the only way is merestartnya.

BIOS create code

BIOS, stands for Basic Input Output System, in a computer system or kompatibelnya IBM PC (computer based on Intel x86 processor family) refers to the routine collection of software that is capable of doing the following:

1. Initialisation (ignition) and the testing of the hardware (in a process called the Power On Self Test, POST)
2. Loading and running the operating system
3. Set some basic configuration in the computer (the date, time, media storage configuration, the configuration process of booting, performance, stability and computer)
4. Help the operating system and applications in the process of the hardware settings using the BIOS Runtime Services.

BIOS provides a low-level communication interface, and can control many types of hardware (such as a keyboard). Because proximity to the hardware, the BIOS is generally made by using assembly language (assembly) that is used by the engine.

You Must Know BIOS Beep Code On Your Computer!

Booting is not perfect

Computer Booting But How Slow Boot Process

Problem:
And booting the computer can enter operating system, but the process is very slow when booting if dilihatdari computer specifications that have not sharusnya podići at this process.

Solutions:
If kompiter slow in the process was due to specification of the processor and memory capacity of a low, that is so halnya.Tetapi if the computer specification is there enough memadahi while booting process masihlambat, that solution should be sought.
Koputer that the process is too slow booting, usually caused by too many programs that is uploaded during a star padfa up. It may make extravagant computer memory. to overcome it, trying to do the following steps:
• Close all applications that are currently active on the computer.
• The dialog box appears Utilities system configuration with the click to make Start Menu Programs> run.
