BIOS Upgrading in Windows® XP
Why you might need to upgrading the BIOS in Windows® XP.
BIOS is the integral part of the computer. BIOS mean Basic Input/Output system. It directs the data flow between the computer’s operating system and the attached devices such as hard disks, keyboard, mouse, video adapter and the printer. The primary function of BIOS is to load and start a computer. BIOS software is stored on an erasable programmable read only memory (EPROM). This software is stored along with the EPROM and if you turn on the computer, the microprocessor passes the control to the BIOS. When BIOS boots up your system, it initializes and analyzes whether all attachments work properly and then it loads the operation system into your computer’s random access memory from your hard disk. BIOS always act as a conciliator between the microprocessor and the I/O device control information and data flow. In today’s computers, BIOS chip's contents could be rewritten allowing the BIOS to get upgraded. Up gradation of the BIOS software to a newer version is necessary to fix bugs or improve its performance or giving support to a new hardware. Today most computer manufacturers upgrade BIOS to enhance its performance.
Various tips for BIOS upgradation are as follows:
- Upgrade with care
- Identify the current BIOS version
- Use USB flash drive and scan it
- Read instructions carefully
Upgrade with care
Try to avoid power failure while upgrading the BIOS. The power loss will not allow you to upgrade the BIOS successfully. SO make sure that your system is connected to the UPS before starting the upgradation. In the case of power failure the UPS will be able to provide adequate power supply. It is good to close all unnecessary programs when you upgrade within Windows®. Sometimes you might face problems while upgrading. Sometimes Windows® might show instability. To avert theses issues, you have to close all redundant programs before starting the up gradation.
Identify the current BIOS version
The user must correctly identify the motherboard model and install BIOS according to this model. Your motherboard model will be printed in the mother board itself. After identifying the motherboard model, then install the latest and correct BIOS version. Otherwise you could not make the upgradation effectively.
Using a floppy disk might be very risky for the user. A floppy disk is very sensitive to the environment and there is a great chance for getting tainted. So it is better to use USB flash drive rather than a floppy disk. Before starting the BIOS software upgradation, it is better to scan the USB flash disk .If your USB flash disk has bad sectors then the BIOS file could get corrupted and perhaps you would end up with some problems. So scanning your USB flash disk or floppy disk will help you a lot.
Before upgradation you must carefully read the instructions. Each manufacturer provides different methods of upgrading your BIOS. Before starting the upgradation process read the instructions for the way that you plan to use carefully and continue further.
