Options
- ABoot device order

Explanation
The BIOS (stored in CMOS) holds firmware-level hardware settings such as boot device order and hardware configuration, not OS-level or software data.
Common mistakes.
- B. The Linux kernel version is part of the operating system software and is stored on disk; the BIOS has no knowledge of or storage for OS-level software versions.
- C. Timezone is an operating system or application-level setting stored in files such as /etc/timezone; the BIOS only tracks the hardware clock value, not the timezone interpretation.
- E. The system hostname is configured within the OS (e.g., /etc/hostname) and is never stored in BIOS firmware.
