The BIOS is often referred to as a system opereasi miniatutr and dedicated to low-level communication with the hardware. BIOS is a software code embedded in a computer system.
The function of the BIOS that is,;
- To provide visual information when the computer is turned on
- Provide access to keyboards
- Provides access to low-level communication between hardware components
The BIOS is a chip that is filled with electromagnetic ways (lighting). The BIOS is generally stored in the EPROM chip (Eraser Programmable ROM) or EEPROM (electronical Erasable ROM), so the technology can be updated when iniBIOS (flashing).
The core components in the BIOS,;
1. BIOS Set-up program that allows users to change the computer configuration in accordance denagn keinginan.BIOS menyembunyiakan details how to access the hardware is quite complicated, if done directly.
2. Drivers for the basic hardware, bleak video adapter, input devices, some devices lainnyauntuk processor base operating system 16-bit.
3. Main Boatstraper program that allows the computer to perform the process of booting into the system opersasi installed.
BIOS UPDATE
Prior to 1990, is in the BIOS ROM chip and unbiased changed. Along denagn complex system and also the need for "bias in the upgrade" so now the BIOS firmware is stored in EEPROM or flash memory devices that can easily be upgraded its contents by the user.
The steps to upgrade the BIOS;
1. Identify the manufacturer of the BIOS maker on your computer. Do not let you do different BIOS update
2. Download the latest BIOS from the manufacturers site
3. You menggunuakan floppy to copy all the files have been downloaded. Use a DOS system in a way (format a: / s) that can be used for the booting process.
4. Boot the computer using a computer diskette that has filled a file download. Once entered into the system, DOS, run the flash program for the update process.
BIOS SETTING
Options in the BIOS which is generally divided in several the category, including; Standard CMOS Features BIOS, power management, etc.. Each category consists of the choice options, for example;
- Standard CMOS Setup; kongfigurasi the most basic hardware such as date, time, hd, drive, video.
- BIOS Features Setup, Configuration for warnig advanced level such as viruses, the internal CPU, Exernal cache, etc.
- Advance Chipshet Feature;. Options to optimize for the expert and professionalism, there is DRAM timings, CAS latency, cycle length SDRAM, AGP aperture, AGP mode.
- Integrated Peripherals; control additional functions such as serial port on the motherboard or parrel.
- PnP / PCI Configurations; should select all the configuration on the choice of auto, except the USB port or a 3D graphics that often create problems.
- Load BIOS Default & Load SETUP Default; to restore the function of a standard before it changed.
- Power Management Setup; increasingly sophisticated enregi saving mechanism, the more confusing it choosing manajemen power.
How optimize the BIOS settings;
1. To get a good ynag BIOS setting auto gunakkan
2. Quick Power on Self Test option Enable
3. Boot Virus Dection. Disable option
4. Internal and External Chace option Enable
5. The idea of an unused port select the Disable
6. AGP Aperture Size choose from half the amount of RAM
7. Select the Enable AGP Fast Writer
8. Boot Sqyence to quickly choose from booting from the hard drive
9. Boot Up Floppy Seek Disable select
10. CPU Speed is produced from the multiplication of the clock and multiplier
