XK0-004 · Question #67

Which of the following information is stored within the BIOS? (Choose TWO correct answers.)

The correct answer is A. Boot device order D. Hardware configuration. The BIOS stores low-level hardware configuration and firmware settings such as boot order and hardware parameters, not OS-level or user-level settings.

Why each option

The BIOS stores low-level hardware configuration and firmware settings such as boot order and hardware parameters, not OS-level or user-level settings.

ABoot device orderCorrect

The BIOS stores the boot device order in CMOS/NVRAM, which the firmware reads during POST to determine the sequence of devices (disk, USB, network, etc.) from which to attempt booting.

BLinux kernel version

The Linux kernel version is stored on the filesystem (typically in /boot/) as part of the installed OS, not in BIOS firmware or CMOS memory.

CTimezone

Timezone is an operating system or user-space setting stored in files such as /etc/timezone or /etc/localtime; the BIOS tracks only the raw hardware clock time, not timezone context.

DHardware configurationCorrect

The BIOS stores hardware configuration including CPU settings, memory timing, enabled/disabled onboard peripherals, voltage settings, and other platform-level parameters that the firmware needs before any OS loads.

EThe system's hostname

The system hostname is an OS-level identifier configured in files like /etc/hostname and set by the OS during boot; it has no presence in BIOS storage.
