CONCLUSION BRIEF BIOS

DEFINITIONS BIOS BIOS (Basic Input Output System) is a standard controller program installed on the motherboard. These programs are stored in a chip in the computer. BIOS (Basic Input Output System), is a program that set the configuration of input and output components are installed padaPC both software and hardware. BIOS, part of the operating system that can identify the set of programs used to boot the computer. BIOS is in ROM of the system, and in general permanen.Program BIOS is stored mikroprocessor used to light komputer.BIOS also regulate the flow of data between computer operating systems and enhancement that is connected to the computer.
FUNCTIONS OF THE BIOS BIOSpun have functions that are important, and the function of the BIOS itself, among others: • initialization and testing of hardware devices (hardware), • create and run the operation system (OS), • set some settings in the computer, • assist the operating system and applications in the process is the hardware settings using the BIOS runtimen service. BIOS PROBLEM Problems can occur in the BIOS, bios may be corrupted by time-life example that was too long, the wrong use of the BIOS, and the influence of the virus CIH virus misalny.
BIOS TYPE Classified into a BIOS chip and filled with ways elecktromagnetic (lighting). In general, the BIOS is stored in the chip EPROM (Erasable Programmable ROM) or EEPROM (Electrical Erasable Programmable ROM). In the market there are so many computer companies that issued the BIOS products, among others: AWARD BIOS, PHOENIX BIOS, AMIBIOS, compaq, IBM Aptivas and Thinkpads, etc..
Securing BIOS To prevent some incorrect settings in the BIOS, done by the hands of irresponsible. Because one of the settings in the BIOS can harm your computer and our own as a user. For that there are some things that must be considered and the reason why we should secure the BIOS, namely: 1. Dirubahnya prevent the BIOS configuration If someone can enter the BIOS seetting, it can easily randomize-ngacak system. Disable hardware or alter the boot sequence, 2. SYSTEM prevent booting Several types of BIOS provide full password for the user. function so that other people can not enter the BIOS settings, and only you alone can enter the BIOS settings. but if you forget the password that you created trelah, then there are two ways we can do is: 1. With reset jumper. This way can be done by following the instructions from Manual Book. 2. And by removing the CMOS battery, then plugging it in again.
