Let me start with reintroducing myself into this forum. My name is Michael Odo. A Nigerian and one of the previous most active members of this great online community.
Well, I know that I have been off from here for quite a very long time due to some hard times but, I am back now and in full force.
Back to the topic of my discussion.
BIOS means Basic Input/Output System. It is a software embedded into your motherboard and which controls everything on your system.
Flashing the BIOS is quite a risky affair and you are better adviced not to try that if nothing is wrong with your computer (though there might still be some people out there like myself who will still go ahead to flash a BIOS irrespective of the fact that nothing is wrong with the computer. I actually flashed the BIOS of a motherboard I just bought newly - Gigabyte P4 Titan - 8S661FXMP-RZ Series .) Yea, I know that it sounds damn crazy bought I went ahead to flash the BIOS of my motherboard because I wanted to incorporate my name (picture should be better) into the system BIOS and I also went ahead to upgrade my BIOS from the previous F2 model to the latest F3 model.
Well, I succeeded and nothing went wrong and right now, whenever I power my system, it displays my name and picture on the monitor's screen during the post screen, before booting the operating system.
Ok, to make the BIOS flashing easier for you, I would recommend you download a free BIOS flashing utility from any of the search engines (Googles or Yahoo is recommended). Make sure that your utility supports the flashing of your particular kind of BIOS (Award BIOS or AMI BIOS). Using the wrong utility can permanently damage your BIOS and that means that your motherboard is gone and gone forever (depending on if the BIOS is fixed or detachable, you have the option of changing the BIOS with another good one of the same model as that you have on your motherboard.
Ok, follow these steps CAREFULLY to flash your BIOS.
FOR AMI BIOS
Step 1
(1) If your mainboard has a BIOS protection jumper, change the setting to allow BIOS flashing.
(2) Make a DOS boot diskette. (See example: Windows 98 O.S.)
Beware: Windows 2000/Me are not allowed to make a DOS boot diskette.
a. With an available floppy disk in the floppy drive. Please leave the diskette "UN-write protected" type. Double click the "My Computer" icon from Desktop, then click "3.5 diskette
(A)" and right click to select "Format (M)".
(
In Win XP simply select the option to make a DOS bootable disc and the OS will automatically make the bootable diskette for you.
©. After the floppy has been formatted completely, please press "Close".
STEP 2
Download BIOS and BIOS utility program from Award or American Megatrends.
Please make sure that you download the particular utility for your kind of BIOS as this can permanently dame your motherboard.
Choose an appropriate model name in accordance with user's manual or based on the motherboard revision that can be found on your motherboard. Unzip or extract the downloaded bios update from *.exe or *.zip to *.rom file (you can download Winzip for free at www.winzip.com).
From the CMOS stup, configure your computer to boot from Floppy (A:\). After the system boot from floppy disk, type "A:\> dir" and press "Enter" to check the entire files in floppy A. Then type the "BIOS flash utility" and "BIOS file" after A:\>. In this case you have to type A:\> aminf330 020429.rom (Assuming that aminf330 020429.rom is your new BIOS rom) and then press Enter.
It will then display the BIOS flashing utility on screen. Please check whether new BIOS tag is correct. Right after that, press Enter to start BIOS flash procedure or press Esc to abort.
Beware: Please do not turn off the system while you are upgrading (flashing BIOS. It will render your BIOS corrupted and system totally inoperative.
When the BIOS flash completed. It will auto restart the system. Immediately go into your CMOS setup (depending on your motherboard manufacturer's configuration, press DEL or F2 as these are the two most popular configuration to enter CMOS setup.)
Normally the system redetects all devices after BIOS has been upgraded. Therefore, I will highly recommend reloading the BIOS optimized defaults after BIOS has been flashed. This important step resets everything after the flash.
Press F10 and ENTER to SAVE AND EXIT from the CMOS. (depending, for older Pentiums, you will be required to also press Y to confirm that you really want to accept the configuration.)
You are done.
FOR AWARD BIOS
The whole procedure is almost the same thing. Follow the procedure till after formatting the diskette, making a bootable diskette, rebooting and booting from your floppy drive.
During the procedures before the BIOS flashing, when prompted, press Y to save current BIOS. If you don't want to save current BIOS, press N to pass this step. Right after that, press Enter to start BIOS Flash Utility.
Input the name that you want to save current BIOS as. In my own case, I input 8S661FXMP-RZ F2.rom to save it. Then I press Enter to start it.
I was upgrading from the F2 BIOS model to the F3.
After the flashing, restart your computer and don't forget to enter the CMOS setup. Load Optimized defaults to load the manufacturer's settings. Press F10 to save and exit. If you want to do any additional configurations in your CMOS like overclocking your processor and stuffs like that (I am one person who likes to overclock my processor. Right now, my processor is running and 3.60 GHz after I gave it a 50% overclocking rate. That is what I call madness of the highest order but, yea, the system is stable except for occassional overheating. Planning to buy a new heatsink though), you will need to re-enter the CMOS a second time to do that.
Well, you are done.
I would like a feedback concerning my little tutorial.
Have a nice day.
