Boot Process in Linux

Leave a Comment
Ever wondered what happens when you power on your computer, what happens in the background till the time you see the linux login prompt.
This is a very common concept and frequently asked in interviews. This process will explain the basic stages  occurring during booting right from the power on to the point at which a login prompt appears.

  
The above figure shows the basic stages that occurs during boot process. Starts from BIOS stage , followed by MBR, GRUB , kernel , INIT and Runlevel.

Now i will elaborate all the sections:


BIOS

  •  BIOS stands for Basic Input/output System. 
  • It is firmware interface or program. When  you turn on your computer , Microprocessor passes  control to BIOS  which is located at EPROM
  • It performs System Integrity Checks (Connected hardware integrity checks which is called POST : Power on self test) that assures proper functioning of attached devices.
  • Detects and initialize hardware
  • Determine the device to boot from , i.e. Cd-rom  or hard drive
  • In simple terms it prepares the system to load an Operating System and executes the  MBR boot loader.

MBR

  • It stands for Master boot Record
  • Located in the first sector of bootable disk. Typically /dev/hda or /dev/sda
  • Size of MBR is of 512 bytes and it has three components : 1. Primary Boot loader Program of 446 bytes , 2.  64 bytes for Partition table info 3.  MBR validation check in last 2 bytes
  • It contains info about GRUB  and executes GRUB Boot loader

GRUB

  • GRUB stands for  Grand Unified Bootloader
  • GRUB configuration file is  /boot/grub/grub.conf
  • If there are more than one kernel images installed on computer, you can choose which one to be execute
  • It displays a Splash screen, waits for a few seconds , if you don't type anything it will load the default kernel image as specified in grub conf. file
  • So , GRUB just loads and executes Kernel and initrd images

KERNEL

  • Kernel being the heart of O.S.  handles all Operating System Process such as memory management , task scheduling and overall system control
  • Load device drivers for the devices
  • Mount the  root file system as specified in "root=" in grub.conf
  • Executes the /sbin/init program
  • As init is the first program that is executed by linux kernel, it has process ID od 1. Check the process id of the same by ps -ef |grep init' 

INIT Process


  • INIT  decides the Linux Run levels.
  • Execute  ' grep initdefault /etc/inittab ' on your system to find the run level
  • Below are the available Run Levels:
                0 - halt
                1 - Single User mode
                2- Multiuser , without NFS
                3- Full multiuser mode
                4- unused
                5- X11
                6- Reboot
  • Init  identify the default initlevel  from /etc/inittab.

Run-Levels

When you boot your linux system , you must have seen  various services getting started like starting sendmail ... OK . these are the run level programs.
As mentioned above, there are 6 run levels in Linux , from run level 0 to run level 6. Run level 0 is for halt or turn off. Run level 1 is mainly used by system administrator and used for system maintains and  repairing process. It is also called single user mode.
Run level 2 is for multi  user mode  without network while Run level 3 is for multi user mode with network.

4 is unused and 5  is for graphical mode and run level 6 is for turn off


Run levels can be identified in linux using directory
#cd  /etc/initatab


  • Depending on your default init level setting, the system will execute the programs from one of the following directories.
    • Run level 0 – /etc/rc.d/rc0.d/
    • Run level 1 – /etc/rc.d/rc1.d/
    • Run level 2 – /etc/rc.d/rc2.d/
    • Run level 3 – /etc/rc.d/rc3.d/
    • Run level 4 – /etc/rc.d/rc4.d/
    • Run level 5 – /etc/rc.d/rc5.d/
    • Run level 6 – /etc/rc.d/rc6.d/
Important files For Linux Boot Sequence"
 
Boot loader 
/etc/grub/grub.conf
/etc/lilo.conf

  
Mount NFS  partition table from the /etc/fstab file
 
Run level it will refers to the /etc/inittab file

Motorola Moto G is one of the highest selling gadget of year 2014. With all the high end features and powerful configuration, phone is completely value for money. At price point of Rs 13,999 for 16 GB version , the phone offers 4.5 inch LCD with resolution of 1280 x 720  and pixel density of 326 ppi. , powerful Qualcomm's Snapdragon processor of 1.2 Ghz , 1 GB RAM and 5 MP camera is decent enough for normal Photography and front camera works absolutely well for video call. I have already posted unboxing of Motorola Moto G when i ordered this phone


Like every thing in this world is not completely perfect, Moto G also have some loopholes.



Pros and Cons of Motorola Moto G:

Pros:
  • Processor is plus point (1.2 Ghz Snapdragon 400)
  • Latest Android Kit kat 4.4.2
  • Gorilla Glass 3 Protection

Cons:
I have found some loopholes in Moto G:
  •  Battery drains off early in case you regularly use 3G on it.
  • Whenever you move from one state to another (on roaming) ,there is problem of signal reception and you have to manually search for signal.
  • In case you like to play FM radio , you can't play it via Loudspeaker (only via earphones)
No second thought, it is still best phone with best features  specs and performance at reasonable price
