Linux System Startup
If you usually run for a coffee refill while your computer is booting up, here's a look at what you're missing.
Today, you can purchase a Linux distribution, install it and use it, all without really understanding much about the operating system itself. For those perhaps new to Linux who want to know a bit more about their OS, this article looks inside the startup sequence of Linux on a PC.
The techie word for starting up a computer is "bootstrapping", and the short version is "booting" or "boot". The initial part of this booting process is performed by code stored in ROM. This code is general in nature and is not specific to Linux. Its task is to load the Linux-specific boot loader and turn control of the system over to it.
