BIOS/UEFI Platform Settings for A+
Short answer
BIOS/UEFI controls how the system boots, what devices are allowed to boot, and whether certain platform security features are active. For support, a technician should know where to look for boot order issues, how Secure Boot can block unsigned boot loaders, whether TPM is enabled for disk encryption scenarios, and whether virtualization must be enabled for certain applications. Temperature readings and fan profiles give quick clues about cooling-related issues, but require contextual interpretation.
Why it appears on the exam
- Identify which firmware setting to check given a scenario (example: USB installer not detected -> Boot options/USB boot). - Decide whether to enable or leave Secure Boot enabled for a given support scenario and explain the reason. - Given a symptom of virtualization feature unavailability, point to the firmware setting that must be enabled.
Key concepts
Concept 1
Required terms
BIOS/UEFI: Firmware interfaces providing low-level platform configuration, boot behavior control, and hardware feature toggles. Boot options: Settings that determine boot device order, USB boot enablement, and legacy/UEFI boot modes. Secure Boot: A firmware security feature that prevents loading unsigned or untrusted OS boot loaders, used to protect the boot process. TPM: Trusted Platform Module support exposed in firmware for features like disk encryption and secure keys.
Example
If a system will not boot from a USB installer, check firmware boot options and USB boot enablement before assuming the installer is bad.

How BIOS/UEFI Platform Settings works
BIOS/UEFI controls how the system boots, what devices are allowed to boot, and whether certain platform security features are active. For support, a technician should know where to look for boot order issues, how Secure Boot can block unsigned boot loaders, whether TPM is enabled for disk encryption scenarios, and whether virtualization must be enabled for certain applications. Temperature readings and fan profiles give quick clues about cooling-related issues, but require contextual interpretation.
Example
If an OS reports encryption features unavailable, verify TPM is present and enabled in firmware.
Concept 3
Common confusion
- Changing Secure Boot without understanding security policy; teach when it is acceptable to toggle it for installation tasks and how to restore settings. - Treating firmware temperature numbers as definitive proof of failing hardware; they are diagnostic cues that should prompt further checks.
Example
For a user wanting to run virtual machines, confirm virtualization support is enabled in firmware (VT-x/AMD-V).
Concept 4
Core 1 (220-1201) question cues
Identify which firmware setting to check given a scenario (example: USB installer not detected -> Boot options/USB boot); Decide whether to enable or leave Secure Boot enabled for a given support scenario and explain the reason; Given a symptom of virtualization feature unavailability, point to the firmware setting that must be enabled.
Example
If a system will not boot from a USB installer, check firmware boot options and USB boot enablement before assuming the installer is bad.
