Kind of - It tells the computer to start up the initial files to get the computer 'up and running'. These are files such as driver programs for the display, keyboard, mouse, screen, printer etc, along with disk controllers, operating system and internet access programs.

What is the difference between sector slipping and sector sparing?
Sector sparing also known as sector remapping / sector forwarding remaps the disturbed / corrupted logical block with the available spare leaving everything else alone. Consider a track with eight sectors mapped to logical block 1 to 7. Sector 8 is not used and has been allocated for spare initially. 1 2 3 4 5 6 7 S S = spare sector Now consider sector 3 has been corrupted as a result sector remapping will result in allocation of spare (S) sector to logical block 3 : 1 2 C 4 5 6 7 3 C = corrupted sector Whereas sector slipping change mapping to skip over defective region. Considering the above example sector slipping will result the following arrangement: 1 2 C 3 4 5 6 7 C = corrupted sector

What is the pre-boot sequence?
Preboot Sequence During startup, a Windows Server 2003-based computer initializes the boot portion of the hard disk and the preboot sequence begins. This sequence consists of four steps: • The computer runs power-on self test (POST) process to determine the amount of physical memory; and • The hardware components are present. • If the computer has a Plug and Play (BIOS), enumeration and configuration of hardware devices occurs. • The computer BIOS locates the boot device and loads and runs the master boot record (MBR). Note: Windows Server 2003 modifies the boot sector during installation so that Ntldr loads during system startup. Therefore you should disable the Boot Sector Virus Protection in your BIOS Setup.

A boot sector virus is a virus that's located in or directly modifies a special part of the hard disk in a computer called the boot sector. The boot sector, in basic terms, directs the computer to the things it needs to load the operating system and user interface so you can use it. Viruses that modify the boot sector can be loaded into memory at the same time or even before the operating system, and can prevent the computer from starting up correctly in some cases. Boot sector viruses were more common during the days of DOS, when such viruses had easier access to the boot sector and other sensitive parts of the system. Today, these viruses are not very common because it is more difficult for them to spread and infect.
