Find another bios file. The awd is some award proprietary file. For uniflash to work you need .bin file.

Hmm, where from?

Will I get these?

I’d say go for a bootlock flash and see if that helps. Also, double-check all your cables and connections to be sure

Where can I get just the bootblock?

I start uniflash, I change the chips, but when I try to flash the bios....

I think that's your problem right here. You change the chips before you launch uniflash.

But you also said later on that the image from your working board works on the asus chip. Might it be that you've done it correctly now?

I don't think this is the problem, but I'll try.
Without exiting the program, I first flashed a7v6x009.awd unsuccessfully, then 7515PLS1.40 successfully.

And if it matters, the first time I flashed all the squares were green, only 2-3 were red - but again unsuccessful.
All subsequent times I tried, all but 2 were red.

uniflash is the best in my opinion, with others usually you have a bunch of different switches you need to add such as
"awdflash bios.rom /cc/cd/cp/py/sn/cks/r", or for afudos "/i /n /pbnc"which tell it what to do including writing the boot block,
also you may have to rename the bios for certain programs to .bin or .rom, as far as i remember for uniflash it can be anything even numbers,
i've used uniflash plenty of times for hotswapping the same chips and never had any problems,
when uniflash loads and you swap your chip, did you make sure to select redetect chip before flashing the bios,
if its all green after flashing, but you still have a blank screen, and you're sure its not your ram, i'd check if your cpu is actually supported by the bios.

Try Flashrom and also change the mobo you're doing hotflash with. I've personally had no success doing hotflashes with ASRock mainboards whatsoever.

I managed to flash the chip with another motherboard - ECS 915G-A.
But the system does not boot again.

I accidentally saw that there is a drop of liquid metal in the AGP slot. I am 99% sure that it shorted at least 4 pins. I cleaned it, but it does not boot again. Maybe it caused damage.

Does it "boot" with the bios from the asrock board? By that I mean do you get any kind of beeping. If it still does then it's the BIOS file at fault or the BIOS chip.
As for the shorted pins check with an multimeter if they are actually shorted. Or tell us the pin numbers so we can check what do they do.

Also an POST analyzer card would very much be useful here. We could tell if the board does something or if it's completely dead.

It doesn't beep.
Again, there is a faint noise from the speaker when it is turned on and again after a few seconds.

These are the shortened pins:
A57 C/BE0#
A58 Vddq 3.3
A59 Reserved

B57 AD8
B58 Vddq 3.3
B59 AD STB0

I accidentally touched this chip from the above picture IP101 and it gets very hot, I can't touch it. I removed it with hot air, but it won't boot again.

I don't have an analysis card, which one should I buy from Aliexpress?

The one with 8 LED's. The one with 3 has bad ISA slot which doesn't even connect to the IC's on it.
Here is an example of a good POST card.

Oh, Vdd shorted with data adresses.... that's not good at all... I think the NB/SB is now dead. But to confirm this we need something to see the post codes.

As for the IP101 I think that's the ac97 audio chip.... If it's bad then low chances the board will work. Try to play around with the BIOS'es from TRW and see which one will flash.
If that's an AWARD bios I think I had some from generic boards I could send you for testing.

I tried 2-3 bios files. They all flash successfully on this ECS 915G-A motherboard.
I ordered the PCI card, I'll write again when it arrives.
