What's A20?

[YourSurrogateGod]

I saw it in an example (this (http://www.osdever.net/tutorials/a20.php?the_id=4) one) and I have no idea what it even is :confused: . I did some quick-looking up on google, but I got a ton of links to consumer products.

I think you better ask that question in the OS Dever forums, because I don't even know this :p. And give me the link if you got an answer.

Go too google and search for: What is the A20 address line
And you will get it :wave:
