This seems to be the standard response. I've spoken to the manufacturer of my laptop and several dealers, they all want to install a new mobo, and charge accordingly!
Because the BIOS IC is soldered in place, they say it can't be repaired! That's complete rubbish, I've already removed it and fitted a socket in its place.
I'm waiting for a cheap programmer to arrive (35 euro's) then I'll reprogram the IC with the image I downloaded from the manufacturers site, and fingers crossed I should be up and running again.
