Discuss what the BIOS does when you first power on a Linux system.
What will be an ideal response?
When you first power on your system, the BIOS on your motherboard takes charge of the boot process and performs several tasks. It:
• Runs a Power-On Self Test (POST)
• Conducts the initial detection and setup of hardware
• Identifies bootable storage devices (such as your optical drive or hard disk drive).
If the bootable device is a hard drive, the BIOS also reads the master boot record (MBR) on the drive. The MBR resides in the boot sector of your hard drive and it tells the BIOS where a bootloader resides on the hard drive. A bootloader is software that the BIOS can load from the MBR of the hard drive that allows the CPU to access the hard disk drive and load an operating system into RAM.
During the Linux boot process, the BIOS starts the bootloader (such as GRUB), which loads the Linux kernel and the initrd image into memory.
