BIOS Updates, start here:
Read and heed all instructions!
Start with the BIOS directory:
Download the correct version. (Betas are not typically recommended, so
this means you want Version 1205.) If you already have version 1205, just
move on down to the memory remapping instructions.
Now go to the BIOS Utilities directory:
You will quicly notice there is not a version for Windows Vista!
This means you cannot flash the BIOS from Windows.
(Your manual will state that ASUS Update can run from windows. It was
not written for Vista.)
Instead, copy the file you downloaded to a USB Flash drive and stick it
in one of the rear slots on your machine.
Additionally, burn this file to a CD (not DVD.) More on this later.
Reboot and press <Alt>+<F2> when you normally pressed <Del> to enter BIOS
This starts the EZ Flash utility. (See section 4.14 of manual. If you
don't see this, do not proceed. Instead follow your manual's section 4.1 for
creating a boot floppy. If you don't have a floppy drive, get one for $25.
Then, use the AFUDOS utility.)
When prompted for a drive, select C: drive which is actually the USB
When offered the option to save a copy of your current BIOS. Do so.
Then, you will select your new BIOS file and select Flash.
Do not do this operation if it's cloudy.
Should you lose power during this 10 second operation, your BIOS will
be corrupt and you're machine worthless until you restore the BIOS. Your BIOS
has an internal check that detects a corrupt BIOS and will seek the CD drive
for a restoration file. Let's hope you don't have to go there.
Otherwise, you have just updated your BIOS, and like 99.9% of everyone
who does this, you won't see anything different other than the text on the
screen when you reboot indicating BIOS version 1205.
Now, back to the ASUS page:
Go to the Manuals directory and download the appropriate language
manual for your computer. (I'll assume English.)
The first thing I noticed is NForce4. This, based on other posts and
Google searches results in the need to move memory mapping of the BIOS to see
all your RAM.
Onward to Chapter 4.
Find section 4.4.4: CPU Configuration
Boot to BIOS. Select Advanced. Select CPU Configuration. Select
Memory Configuration. Set Hardware Memory Hole to Enable.
Hope that fixes you up!
