Here's the manual, you should look at it (section 2.1.4) and print those 3-4 pages if possible. You'll want them for reference so you can do this exactly as it requests and it'll make more sense. You'll need a flash drive, and the motherboard's support cd (likely driver cd), which has a DOS environment boot for it. Also I just read your message before posting this, yes an external hard drive will also work. You just need somewhere to store the files.http://dlcdnet.asus.com/pub/ASUS/mb/SocketFM2/A85XM-A/E8004_A85XM-A.pdf
Here's the bios utility that needs to be extracted, and copied to a flash drive.http://dlcdnet.asus.com/pub/ASUS/misc/utils/Bupdater_V130.zip
And here's the actual bios file that it will reference, also should be copied to flash drive:http://dlcdnet.asus.com/pub/ASUS/mb/SocketFM2/A85XM-A/A85XM-A-ASUS-6603.zip
Now I'm just going to shorthand the steps (they are in more detail in the manual which you should reference).
1) restart to computer, tap f8 to choose boot order. Insert flash drive before starting computer. The flash drive should have the updated utility AND the bios file, already unzipped and copied to it.
2) Choose dvdrom as boot device to access the support cd.
3) From the dos prompt, navigate to the flash drive. It can be any drive letter but it will likely be d:. So you'll type d:
and hit enter.
4) Run the updated by typing it's name and hitting enter. bupdater.exe
and hit enter. If it doesn't find any file, then switch to C:
(C: and hit enter) and type it again and hit enter. Try again with E:
. It will be one of those letters, but it changes based on how many hard drives you have, etc. Furthermore, be sure when you unzip the bupdater, that you navigate to the files and copy the two files directly to the flash drive (not the folder where the files reside)
5) Once the updater is running, tell it where the new bios file is located (also on the flash drive). There's pictures in the manual.
Continue on, let it update, when it's finished it'll restart. When it's updating it's absolutely crucial you let it finish. I can't stress this enough. Only restart when it's ready to. The utility will backup the current firmware, so this process can be reversed if something goes wrong.
If you get stuck anywhere, and you're not in the bios updating portion, just get back to me and i"ll try to guide you in.
This is an advanced process, but relatively harmless if you follow the directions.
I'm also going to post a few DOS commands to assist you.
Drive letter changes are x:
hit enter. X beign the letter
Directory listings are dir
Changing directories, cd nameoffolder
Dropping down a directory, cd..
and hit enter.
Dropping down to root drive path, cd\
and hit enter.
This dos should support DOSkey (name completion), where as if I type BUP
and hit tab, it will auto complete the rest of the name.
Let me know how it goes.
