The BIOS Chip Recovery

I hope many of you will thank me for this. I'm not overestimating, because what I'm about to tell you is a little secret that almost everyone can do. I mean almost, because not all of you know how to do it or you don't have all the resources needed for this. I must tell you that this article contains certain information that require some technical skills and also I must use a disclaimer. I can't be responsible for your actions. The technique involved works, I used it several times.
OK, let me tell you what this is about. How many of you flashed a BIOS with the latest version available? ...you must than know that there is a small chance of write failure or power failure during the update procedure. What happens then?? YOU MAY WANT TO THROW THE MOTHER BOARD TO GARBAGE; at least this is the first tendency. DON'T! There is a way that you can "recover" your BIOS back.
If you don't know how to flash a BIOS check this .
Basically a BIOS chip is a EEPROM(Electrically Erasable Programmable Read-Only Memory- I won't enter in further details) or flash memory device. That means that the BIOS code is stored in a memory device and the computer on startup reads the instruction code in the BIOS and let's say it does his job there for the computer to start up.
You're saying it's not possible? Sure it is, but you need a specialized flash programmer that allows you to write back the BIOS you want.
What about every one else that can't afford one or don't know how to do that? Well you need to gain access(own or know someone who does) to another mother board exactly like yours. The basic idea is that if your mother board won't start up for another BIOS flash, you flash the BIOS on another motherboard.
Let's take it slowly:
1. the first, after the part of finding another mother board exactly like yours, is to extract the BIOS chip from your MB. Be very careful not to crack it or bend it's pins. If you own a chip extractor use it, or else use a pin with a bended end and slowly get the chip out of it's socket. Maybe you should write down or make a schematic on it's socket positioning;
2. the second step is to take the "new" MB and start the process of flashing the BIOS. make sure that the flash program won't auto start or if so keep pressed Shift so the autoexec.bat won't execute. It's important to do it this way;
3. when the flashing program gets to the part when it should write the new BIOS on the chip(usually they ask permission to do this), this is the part where you interfere;
4. CAREFULLY you take the good BIOS chip out of it's socket(make sure you don't touch any connections on the MB, case of a short-circuit);
5. place in the socket the bad BIOS chip(watch out for any bended pins before placeing an make sure it's right positioned);
6. go ahead with the flashing procedure;
7. After everything is done, stop the computer, take out the "new" BIOS and place it on your mother board.
It should be like new!
