Is there a way to fix a wrong bios flash? The file that i used must have been the wrong one and now the computer will not boot! It is an ECS mainboard (k7s5a) and the bios chip is an AMI bios.

Generally not unless you replace the bios chip. Once the bios is flashed with the wrong version, it's usually not fixable. I've replaced system boards because of this.

Sometimes replacing the bios isn't enough. Other capacitors usually fry at the same time. Replacing the system board resolves the whole issue.

Start by re-setting the CMOS memory.

I thought I had killed a motherboard with a BIOS update. Turned out that the BIOS changed enough to require a full reset of the CMOS memory BIOS settings.

If you did install the wrong BIOS, and the motherboard does not POST, you have 3 options:

Contact the motherboard mfg / local dealer to see if you can purchase a BIOS chip.

Purchase a BIOS upgrade from Unicore software. www.unicore.com

Find a friend that has a EEPROM programmer. (Someone who works as an engineer in an electronics company is a potential source.)
And have them re-programm your BIOS IC with the correct BIOS code.

Beyond that, a new motherboard is your next option.

Generally in the past mainboard replacement is your most cost effective option but, I have also seen more BIOS flash utilities that offer the ability to make a back up copy before the flash process is carried out. I would recommend booting up on the floppy disk you flashed your BIOS from and then start the flashing program again to see if it has a restore option.

You did not specify the beeps length and frequency, anyway, the beeps could indicate two things of that I know, one, is bad or not working RAM (the pins are loose) and two, bad or not working AGP/VGA card.

So you should first try to clean the pins on the RAM and AGP/VGA by rubbing them on both sides with a pencil eraser (I do it a lot of time) to make them clean and free from obstcles that preventing them contacting the slot sockets.

Because I am not sure if you have bad BIOS since you said there are beeps sound, but if you are sure it's from the wrong BIOS flashing then go to this site and you'll find good advice there.
