This is a picture of a ridiculous PC error. It says that a keyboard is not found so you need to press F1 to continue or DEL to enter Setup. But, dude, there is no keyboard. How can you press something without a keyboard?
Here an interesting picture of keyboard. So did you check your keyboard? I know I did when I first saw this picture!
Very funny apple keyboard. This keyboard have just letters a p p l e and nothing more. Apple are so creative and interesting that people buy their stuff even if it is not the best. I think apple can sell every product what they made and this funny thing too.
