I've been wondering about this for a while. How is it that people can take the BIOS from a console and make it work on a computer?
Any answer would be greatly appreciated.

The BIOS is just some built in code that interacts with the hardware on behalf on other code. It must be accessible to the processor like anything else, and on Von Neumann architecture machines code is data so it can be read like any other data.
That's not to say that it isn't difficult to access. Systems will often be designed so that once the BIOS has finished setting things up it is no longer accessible. So there may be some hardware hacking involved...
