This is the largest collection of beep codes I know of.

Section 2.1.3 in the user manual indicates the board
has "Crashfree BIOS 2". Your motherboard CD contains
a BIOS file at the root level of the CD, and depending
on what version of the BIOS that happens to be, you could
try to recover the motherboard with that. If you had
a Sempron for example, you may want to do a BIOS recovery
with a later version of the BIOS than the one on the
motherboard CD. (The paper label on the BIOS chip
may indicate the release number of the factory BIOS.
Compare it to the table on this page, for your board.
http://www.asus.com.tw/support/cpusu...pusupport.aspx )
Crashfree supports operation from a floppy disk or from
a CD. According to the manual, CrashFree will look for
the exact file "A7V600-X.rom" on either of those disks.
If you download an Asus BIOS to flash, you would
rename the file to match the above file name.
Boot block recovery is another form of BIOS recovery,
and in that case, a floppy containing a MSDOS boot
system, an autoexec.bat with a one-liner BIOS flash
command, a BIOS flashing program, and the BIOS file,
could be used to reflash the BIOS. But, in a sense,
CrashFree is the same thing, as you are relying on
the CrashFree code in the Boot Block of the BIOS
chip, to orchestrate the recovery. I would think if
CrashFree doesn't work, or the BIOS cannot get past
the error condition it is finding, then attempting
recovery via a Boot Block procedure won't work either.
For the Boot Block procedure to work, you would need
to be seeing the BIOS making attempts to read the
floppy drive - if it won't touch the floppy drive,
then another recovery procedure will be required.
What typically has happened to most users, is the
BIOS flashing program erases the Boot Block and
the Main BIOS code, and then the new code fails to
be flashed into the chip. With the Boot Block
erased, there is no longer any CrashFree code
available to run. (CrashFree would only really
live up to its name if there were two BIOS flash
chips. Some Gigabyte motherboards have that
feature.)
Now, since you are getting beep codes, that means
there is _some_ amount of BIOS code present. What
I cannot tell you, is where that BIOS code is
getting stuck. If somehow, you flashed the wrong
motherboard BIOS into the board, there is no way
to predict what the symptoms might be. Try
inserting a floppy into the floppy drive, with
a .ROM file on it for Crashfree to use, and see
if the BIOS will read the floppy. Wait several
minutes, as you don't want to interrupt the
flash operation, if it is happening.
If you visit the badflash.com website, they offer
a service, where they will ship you a BIOS chip with
a BIOS code programmed into it. In a couple of
days, you could have a BIOS chip in your hand. You
unplug the computer, take note of the BIOS chip
orientation (has an arrow on the plastic top), pull
the old BIOS chip out with the "U" shaped tool, then
push the new chip into place with your thumb. You have
to be careful not to bend the pins in the BIOS chip
socket while doing this, which is why the "U" shaped
removal tool is a good thing to use. The arrow mark
on the top of the new chip has to match the alignment
of the old chip, as otherwise the chip will get
burned.
In some countries Asus also offers the BIOS chip
replacement for $25, but it may take Asus longer
to ship the chip to you, than an Internet-based BIOS
chip replacement firm like badflash.com .
When doing the "clear CMOS" procedure, I hope you
have been unplugging the computer...
Good luck,
