Question

Adrian, the Network Administrator for Peach Tree Inc., wants to install a new computer on the company's network. He asks his assistant to make a boot disk with minimum files. The boot disk will be used to boot the computer, which does not have an operating system installed, yet. Which of the following files will he include on the disk?

Options

  • AIO.SYS, MSDOS.SYS, COMMAND .COM, and AUTOEXEC.BAT.
  • BIO.SYS, MSDOS.SYS, and COMMAND .COM.
  • CIO.SYS, MSDOS.SYS, COMMAND .COM, and CONFIG.SYS.
  • DIO.SYS, MSDOS.SYS, COMMAND .COM, and FDISK.

Why each option

The minimum three files required to create a bootable MS-DOS disk are IO.SYS, MSDOS.SYS, and COMMAND.COM; all other files such as AUTOEXEC.BAT and CONFIG.SYS are optional.

AIO.SYS, MSDOS.SYS, COMMAND .COM, and AUTOEXEC.BAT.

AUTOEXEC.BAT is an optional batch file executed at startup for user-defined commands and is not required for the system to boot.

BIO.SYS, MSDOS.SYS, and COMMAND .COM.Correct

IO.SYS and MSDOS.SYS are the two hidden system files that contain the MS-DOS kernel and I/O subsystem, while COMMAND.COM is the command interpreter that provides the user interface. These three files are the absolute minimum required for an MS-DOS system to boot and function; no other files are mandatory for the boot process itself.

CIO.SYS, MSDOS.SYS, COMMAND .COM, and CONFIG.SYS.

CONFIG.SYS is an optional configuration file used to load device drivers and set system parameters at boot, but it is not required for a minimal boot disk.

DIO.SYS, MSDOS.SYS, COMMAND .COM, and FDISK.

FDISK is a disk partitioning utility used to create or manage disk partitions and is not a system boot file required to start the operating system.
