BIOS, which in full means Basic Input Output System is a very important component in the computer system. BIOS helps the Central Processing Unit of a computer communicate with hardware devices as it has software especially for that role. Some of the devices that the BIOS helps the CPU to communicate with are screen play, mouse, keyboard, hard drive and so on. The BIOS is normally stored in the ROM. A user may be required to upgrade their BIOS after a certain duration of time. The upgrading needs to take place if there is an advanced operating system. Users that operate Windows XP can either upgrade their BIOS or change it altogether. Many users opt to upgrade their BIOS instead of changing it as the position of BIOS in ROM makes the process of changing the BIOS very difficult.
The PCs of modern computers contain flash BIOS. This means that a user can upgrade when they want to. Prior to upgrading BIOS in windows XP, the user should make sure the set up they want to use for the upgrading suits their computer. This will help to prevent the BIOS from being corrupted. A corrupted BIOS can make it difficult for a user to start their PC. To get proper information regarding compatibility of the set up and computer when upgrading under Windows XP a user should ask the manufacturers about the most suitable setups for their PCs.
Most of the programs used to upgrade BIOS require booting to DOS from users so that they can get the opportunity to make them run. This is a precaution users should not overlook if they want to upgrade under Windows XP. This is because Windows XP can crash during the upgrading and if it does the user might have to return the motherboard to the manufacturer to reinstall BIOS. Booting DOS from a floppy used for startups is the easiest way to make sure DOS is booted. To create a floppy for MS-DOS startup, the user should place a floppy into the floppy drive then click ‘start’. They should then click ‘My computer’ then Right -click A: drive then click “Format”. One should then check for “Create an MS-DOS start up disk” Finally the user should click the ‘start’ button. A user may need to change the boot devices order in the setup of their computer’s BIOS when booting from the floppy.
