Every Linux distribution embodies some more or less clever hack for circumventing the normal boot process and causing your computer, when it is turned on, to organize itself, not as a PC ru
Linux exploits this chink in the defenses. Your computer notices a bootable disk in the floppy or CD-ROM drive, loads in some object code from that disk, and blindly begins to execute it. But this is not Microsoft or Apple code, this is Linux code, and so at this point your computer begins to behave very differently from what you are accustomed to. Cryptic messages began to scroll up the screen. If you had booted a commercial OS, you would, at this point, be seeing a "Welcome to MacOS" cartoon, or a screen filled with clouds in a blue sky, and a Windows logo. But under Linux you get a long telegram printed in stark white letters on a black screen. There is no "welcome!" message. Most of the telegram has the semi-inscrutable menace of graffiti tags.

The only parts of this that are readable, for normal people, are the error messages and warnings. And yet it's noteworthy that Linux doesn't stop, or crash, when it encounters an error; it spits out a pithy complaint, gives up on whatever processes were damaged, and keeps on rolling. This was decidedly not true of the early versions of Apple and Microsoft OSes, for the simple reason that an OS that is not capable of walking and chewing gum at the same time ca
