2. Boot Process of Linux

3. The LINUX System:

4. When computer is turned on, it executes
boot code that is stored in ROM.
That code figure out how to load and
start the kernel.
Kernel probes the systems hardware and
then spawn system init process.

5. Automatic and manual booting
 Linux system can boot in automatic or manual mode.
 In automatic mode, system performs complete boot
procedure on its own.
 In manual mode, system follow automatic mode up to
certain point but then turn over control to an operator
before initializing scripts are executed.
 At this point system is in “single user mode”, most
system processes are not running and other users
cannot login.
 In day to day operation, automatic booting is used.
 Manual booting is done mostly for system maintenance
activity or troubleshooting problem such as file-system
corruption.

6. Steps in Boot Process
 Typical Linux boot process consists of following
phases:
 1) Loading and initializing of the kernel
 2) Device detection and configuration
 3) Creation of kernel threads
 4) Operator intervention (manual boot only)
 5) Execution of system startup scripts
 6) Multiuser operation

7. Insert CD in CD-ROM..

What is a Partition?
Partitioning is a means to divide a single hard
drive into many logical drives.
A partition is a contiguous set of blocks on a drive
that are treated as an independent disk.
A partition table is an index that relates sections
of the hard drive to partitions.
