don't use the asus online bios upgrade utility!!!
I think they called it "live update utility."
When you do this well, it goes fine. but it can be challenging to just find a straightforward instruction. Since I have updated BIOS on a couple Asus boards, I have made my own notes. I will post them here, below.
I agree that there is not necessariliy a need to update. Better to let sleeping dogs lie. I myself was looking at some compatability issues, such as getting mb to be able to use a newer CPU.
I myself have decided to upgrade BIOS to next-to-most-recent version unless I need most-recent version specifically.
There are two key, crucial steps that are not obvious: first, back up all data files! However you want to back them up. Just in case you mess everything up. next: when bios is done updating, you need to follow instructions to re-set the cmos!
and a third: you will need to determine the bios name for the a8n-sli bios, regardless of version. it wants a file of some specific name - you will need to rename the bios file to the correct name. this info is in the mb manual.
**I have no idea what your computer literacy level is. I myself and great at getting into difficulties, then figuring it out in the long run - an hour, a few days. Largely by expereince and hunting around enthusiast websites including techspot. If you need help, you may need to go to a computer repair place in your neighborhood. I have no way to totally coach a beginner in a brief note. I remember the days of "DOS, and remember working in DOS - many ppl today are not familiar with DOS commands such as cd/a:**
UpdateBIOSinstructions
Get desired BIOS
[mb websites should have info on each bios, as bios adds ability to handle things such as recent cpu etc.]
Figure out correcnt name – [sometimes, will not yet be correct name, but will have a download name, or be zipped.]
Put this correctly named bios on a floppy with AWDFLASH.exe
Make note of this name somewhere, since you will have to type it out soon…
Have a windows boot disc.
Shut down computer.
Restart computer with boot disc in floppy drive.
You should get dos prompt. Get to a:
1. It sez
c:\
2. You enter a:
C:\a:
3. You hit return.
It should now have
a:\
at this a: prompt, type
awdflash
and hit ‘return’ button (same as ‘enter’ button.)
it will ask for the file name of the bios you want. Enter that name.
for example
m2nsli.bin
hit enter.
Some things will happen.
Do NOT select option to “save” old bios.
A long time of flashing will occur…
When bios is done updating, DO NOT CONTINUE; turn the computer OFF definitively—
Pull power cord, let computer sit for a minute.
--some people say that capacitors will hold power for 5-10 minutes,
enabling computer to hold the old bios.
AND
Clear CMOS. This may be essential to avoiding a confusing episode!!
People believe CMOS battery power can be used to sustain the former bios!!
CMOS can be cleared by either pulling CMOS battery
(a battery that usually looks like watch battery)
Or pull the jumper that ‘clears’ the CMOS: manual would be needed to pull the jumper.
I find it easier to pul a jumper than to remove a battery.
So pull plug AND pull CMOS juper or batt.
Press on/off button a few times. This is a superstitious behavior that is believed to clear any residual power out of the mb capacitors.
Now, wait a while.
Get a refreshment.
Restart.
If you have restarted because you have changed processor,
anticipate seeing an “error” message about “CMOS error:”—
If you see this, it is GREAT!!
--this means that the computer has figured out that the CMOS settings do NOT match your comp-
Because the CPU has changed!
It will act appropriately.
Done. Test.
