Updating of the BIOS
The BIOS ensures that the mother board works properly. This large board holds all the devices, so we recommend keeping it updated at all times.
Through this operation you can add supports for new peripherals. Boards made after 1994 usually allow updating by software (Flash Bios), but for those prior to that date it is necessary to replace the chip of the bios.
If it is not done correctly the mother board may be made useless. Never interrupt the operation once it has started. It is also possible to update the bios from other devices such as graphics cards, modems or network cards.
In the case of the last two, if the operation is not successfully completed you can reinitialise and start again; however, if there are problems with the graphics card it is possible that nothing will be seen on the screen after reinitialising the computer.
Updating is a delicate, dangerous operation.
The updating of the bios is usually done in a DOS environment. Before doing it, open up the manufacturer's website, search for the installation instructions and follow them to the letter.
Create a temporary folder (which you could call "Drivers", for example) and download the manufacturer’s software into that folder.
When you download the updating files you will find a file called "README.txt" which also has detailed instructions.
The next step is to create a start-up disk and save the downloaded files from the Internet onto it.
How to create a start-up disk
Insert a 31/2 diskette in drive A.
In Explorer, click on the right-hand button of your mouse and select the "Format" option. A new window will open, so now mark the check box "Copy system files" and press "Accept". Your new start-up disk is now ready.
Copy the files from the temporary file ("Drivers") and add them to the diskette in drive A. Leave the diskette in drive and boot up the system.
Note: it is only possible to create these disks under Windows 3.* - 95.* or 98.* . It is impossible from Windows NT or 2000.
Bios is usually configured so that it starts by default from drive A. If this is not the case, configure the bios to change the order. Once the computer has been reinitialised from diskette A, run the program to update the bios.
