Modifying a Laptop BIOS for Fun and Profit

19inchdellIn today's hack, we will analyze and modify a laptop BIOS image for fun and profit. Note that this is stupidly dangerous: a bad flash and we'll end up with a doorstop, or we'll have to remove the chip and reflash it manually. But in either case, the outcome can be fun.

Technologies used/Requirements

* Laptop (I'm using a Toshiba Portege 3020ct)
* hex editor (I use ht)
* simple image editor (I used MS Paint - I had a reason!!)
* DEBUG.COM from The FreeDOS Project
* Linux Open-Source Fun: Modifying a Laptop BIOS for Fun and Profit Linked by LT Hacker
