LOL Oh No ya don't! That's not the right question. The question can only be properly answered by you reading through the manual or ASUS website's instructions for that specific mobo. I have one and I've updated it 3 times but I can't give you what you need to do the job - deliberate confidence. That will only come from you and ASUS. All I can tell you is that you will need the latest BIOS image downloaded and copied to either a floppy or a USB stick and DON'T for any reason shutoff the computer until it completes, no matter how long you think it should take. You will get messages and a progress bar so you will know if you did it right or if you do something wrong and it fails to load the new image. FWIW as long as you let it complete and even if it fails the BIOS will still function properly. The only danger is shutoff before completion or a wrong image. If you insure you get the one for your model it's quite safe. I can only imagine all the paranoid warnings are for those that don't bother to read and check their steps off and just enter in blindly. Don't be blind. Do it right or take it to a tech who will do it properly.

I know that i've to read the manual and i 've to do this by myself. But i was just asking you some support to my quest in this procedure.

First question, if i update BIOS , i've to reinstall the S.O. ?

I'm not certain what you mean by "S.O." but I can't imagine anything would need to be reinstalled especially way up at operating system level. Remember BIOS is an acronym for Basic Input Output System which is just a set of instructions orchestrating how all the many chipsets on your mobo and in peripherals communicate with each other. BIOS is essentially a Ready? Set. Go! device. It just makes certain everything can communicate correctly and then hands it all over to a bootloader which passes it on to an operating system.

This is the reason a BIOS update could help. The older BIOS image firmware was made before some kinds of RAM chips were available. Sometimes this means that no amount of reprogramming can help but in many cases it is possible with just a few instruction changes to handle things it wasn't designed for or possibly even imagined when the original BIOS was released. It can be as simple as an instruction that increases the address range or adopt a new range the system is to monitor and then utilize.

S.o. operating system, Linux. I asked this cause I read in a blog that before installing bios you need to update driver of Chipset..in the operating system..

Look, like I said in a previous post, I managed to find the exact manual of your motherboard:

http://ftp.tekwind.co.jp/pub/asustw/...A8N-SLI_SE.pdf

Also there http://ftp.tekwind.co.jp/pub/asustw/.../A8N-SLI%20SE/ are all the BIOSes released.

You use now this one: http://ftp.tekwind.co.jp/pub/asustw/...E/A8NSE203.zip
The latest is this one: http://ftp.tekwind.co.jp/pub/asustw/...E/A8NSE502.zip

Also, I managed to find the official Asus China page for your motherboard (in English thought)
http://support.asus.com.cn/download....1&m=A8N-SLI+SE

To update the BIOS, you need a perfectly functional floppy drive and a perfectly good floppy, which you should made bootable in DOS.

Floppy images like that you will find in Internet, first you should experiment carefully that you manage to successfully boot to MSDOS 6.22 or FreeDOS from that floppy.

According with the manual, you should download "A8N-SLI SE Bios version 0502" and "Phoenix-Award BIOS flash tool V1.17", extracting both archives to floppy.

So, you save A8NSE502.BIN as A8NSLI-B.BIN and save it to a floppy disk, in its root directory. The AWDFLASH.EXE you save to floppy with name unchanged.

Finally, follow the manual's procedure to update the BIOS, booting from this floppy.

In case of errors, the motherboard is capable to auto-re-flash the BIOS file from your floppy, BUT as safety measures, create also a CD which contains in its root folder the BIOS file with the name A8NSLI-B.BIN, for emergency re-flash, and I strongly recommend you to triple triple check that all things are OK, as floppy drive and CD drive, also as floppy and CD.

AGAIN, read extremely careful the manual and the troubleshooting pages from Asus site, trying to understand and memorize perfectly everything, because you have one shoot, then you are alone to troubleshoot the issues if errors.

---------------------------------------------------------
Finally, I for one I would use FLASHROM https://www.flashrom.org/ instead for flashing, it works nice within Linux.

I made many times BIOS updates via FLASHROM. Heck, I managed even to contribute in the past with a driver for it (it is called pony_spi) to emergency saving a laptop of a friend.

AGAIN, you should read carefully how to use it, and if you use FLASHROM and you get errors, the fundamental rule is to NOT STOP/REBOOT the system and to contact the FLASHROM developers for help.

For that, is better to use an UPS (Uninterruptible Power Supply), thing I strongly recommend also while doing a standard update.

---------------------------------------------------------
AND as bottom line, be aware that you mess with the hardware, and you can put it down.

Please DO NOT trust me and my words, instead you should read carefully the official documentation and understand what you do.

PS. The Linux does not need updating the chipset drivers before updating BIOS. Anyway, you use the latest ones, given by Kernel.

FWIW and assuming your mobo was bought by itself and not some OEM versioned BIOS pretty much all options should be visible. Many OEMs hide options to avoid user caused errors. For those I have used a DOS program called MODBIN to unhide or alter options but that can be substantially more dangerous than a simple firmware update, which I consider trivial and you probably will, too, once you do one. Good Fortune, mate.

Good guys, thank you very much for your continued support ,

I wanna give you good news , i update BIOS and now everything works !!!

i used the utility inside my mobo (ALT+F2) and the .BIN burned in CD - ROM, cause i dont have floppy drive.

it was really simple and fast, i read all the manual and then operate it.

I was afraid cause Upgrading BIOS was the last thing i never done from when i have computer.

Reading on internet i found some strange theory,
"upgrade before the chipset driver in the operating system and after BIOS..."

However it was a good experience, thanks all of you (in particular enorbet, darth vader)

PS for the forum's master, i think it's more correct to change the subject of this topic or section,
cause it was an hardware problem, decide you how is better to do

That's great news! Congrats andros976.
