Hi All,
I tried to upgrade my BIOS using the latest version of ASUS Update
on Vista x64 system. The first try erased present BIOS and flashed 100%. The
checksum verification failed at 0% as seemed unable to read from
motherboard. The status screen instructions said to try again. So I tried
again and erase said 100% but nothing else happened. No matter how many
times I clicked. On re-boot motherboard is dead. PS and fans come on but
nothing else happens.

Anyone have any ideas?

There is a thread here with a similar result.

Badflash.com can sell you a new BIOS chip. You can have it programmed with
whatever BIOS version you feel comfortable with.

The BIOS consists of two sections, the main BIOS code and the "boot block".
The "boot block" contains enough code, to perform a recovery from a bad
flash attempt.

Ideally, the boot block would be installed at the factory, and it should
never be updated. If the boot block was never erased, and no attempt was
made to update it, then no matter how many times you erased the main block
by accident, you could always recover.

The problems come, when both the main code and the boot block are erased
at the same time. It is during that time, that there is no recovery possible.
If the boot block is erased, there is no "CrashFree to the rescue".

I'm convinced this problem could be solved, if the motherboard makers
wanted to solve it. But for now, it's a $25 donation to Badflash.com
that is going to get you running again.

If there was any video on the screen at all, then I could see a recovery
possible. On some older BIOS, listening for attempted floppy access by
the BIOS, would be a sign that the boot block was still present. But since
you don't mention any signs of life, then pulling the BIOS chip and installing
another one, is the quickest answer.

In the past, I would have recommended a BIOS Savior from ioss.com.tw, but they
don't make a version of the BIOS Savior which is big enough to shadow the
BIOS flash chip size Asus is currently using.

I was hoping to see a BIOS chip socket but no luck! Not sure which chip. I
can do simple soldering but the chips on the motherboard have very small
leads. There is no way I going to get the chip out. I am hoping option 3
below involves sending the entire motherboard back to ASUS for repair.

This is what ASUS customer support sent back:

1. If you have access to the internet via another computer please go to
http://helpdesk.asus.com and click on the Order Bios link and fill out the
information needed to order a new bios chip.

2. You can mail your bios chip into us with a five dollar check or money
order to cover shipping. Please send your chip properly packaged to protect
against damage to: ASUS Technology, Attn: Bios dept. 7100 Intermodal Drive
Suite A, Louisville,KY 40258. Any chips not properly packaged will be
returned to the customer un-opened and unflashed.If you are in Canada the
charge for flashing a chip or purchasing a new chip will be 35 dollars U.S.
If paying with a credit card, it will need to be MasterCard or Visa as the
are the only two we are allowed to accept at this time.

3. You can contact our Bios dept at 812-282-2787 and ask to be transferred
to ext. 5126. If contacting our bios dept by phone please go to
http://helpdesk.asus.com and click on the sign up for new user link and
generate a case ID making sure that you put all shipping information in the
problem summary box.( Do Not Put Credit Card Information In when submitting
this all credit card information will be taken by a bios dept
representative.) If you do not have access to the internet to submit a case,
then when you call in please wait for one of our Tech Support operators to
generate you a case before transferring to our bios dept.Again do not give
credit card information to anyone but a bios dept representative.

OK, I am sure is see the EEPROM chip. It is a little 8-pin DIP between the
ICH8R southbridge and the last PCI slot. It has part number X80VIG and seems
to have marker ink X or A written across top. It has an undocumented 7-pin
connector by it labled J1_SPI. I guess a small 8-pin chip could be within my
soldering abilities. I seem to recall even old cheap motherboards had
sockets for the EEPROM chip. I wish the ASUS would have indicated the chip
location in the manual. Maybe I can get out of this for $5.00 I will keep
everyone posted to progress.
