The Shiny Black Brick in the Wall

I was messing around with my eee Pc 1000 trying to come up with a modded to bios fix the DSDT table whatever that means.... Of course I managed to reduce it to a functional level of a brick. So now I am in a desperate need of a hardware samurai, someone who is comfortable wielding a soldering iron around and can tell the difference between a BIOS chip and let's say a CPU. Reading some forums I endured the sock of notions like SPI flasher and Atmel AVR but I have no idea what they mean.
Anybody who knows what I am talking about ( cause I don't) : Please HELP!!!! :)
