Thanks for your reply Brett.
I ordered the BIOS chip from bios-repair.co.uk
And no I used just a standard soldering iron with a fine tip.
The reason it did this to the board is because I used a needle to bend each leg of the bad chip as the solder melted. Obviously it created too much force and ripped some contacts off.
And yes, this is the first time I have tried this sort of thing and I learned a lot from it
