Hi All

I have an old machine with an AV7 motherboard(Rev 1.02) 900mhz 256mb
ram(generic) that I use as a second machine.

It was running OK before but I was getting occasional crashes/freeze-ups so I
tried to update to the latest 1011 Bios from the asus site. The update seem to
go OK. It reported back that the flash was successful and that I need to power
down and then restore default bios settings etc. But after powering down and
power on again nothing happens. I mean the PSU powers up, CPU fans are
running,
but I get nothing on the monitor (no signal seems to get sent so monitor stays
off). I don't get any error beeps. Nothing else happens.

If I take out the ram then I do get the No RAM Detected beeps, does this meam
the bios is still functioning in some way ?

Please can any help me get this machine back up and running.

Thanks

Wai

For A7V family boards, I recommend checking this site before flashing.
Asus also has warnings on their site, but this site has more info
that may help you.

If nothing else works out for you, there is always http://www.badflash.com
to the rescue.

"Hot flashing", where the flash chip is removed from the bad board,
and plugged into a good board and flashed while the good board is running
is another alternative. This could damage the good board, so if you want
to remain friends with the owner of the good board, this would be the
option of last resort. If the flash chip is a DIP plastic (dual inline)
package, removing the chip and plugging it into another board isn't
that difficult, but you would almost need the donor motherboard to
be assembled on a piece of cardboard on a table top, in order to
safely access the flash socket on the donor board. Tools used to remove
the flash chip while the good board is powered should be plastic, to
eliminate the possibility of shorting pins on the chip while it is
powered.

For any flash repair of the above types to be possible, the flash chip
cannot be soldered to the board - it has to be socketed so the chip can be
removed. If the chip is soldered to the board, this leaves the "boot block"
method, which relies on a small boot loader still being alive inside the
flash chip. For the people who have tried this, I've never gotten a
post back saying it worked, so I have to assume that the "boot block"
method, of preparing a floppy with an exec file on it to blindly try
reflashing the chip, is also a low probability of success. Boot block
methods are more likely to work on newer Asus motherboards with the
CrashFree or CrashFree2 feature.

I don't know if it applies to this board or not, but I had an older
board, that looked to be messed up after being flashed. Everything
seemed to go as a normal boot should, but no Video. It needed a PCI
Card to see the Video and to get into the Bios! Then you could change
back to AGP and all worked OK. Hope that's true in this case too!
