Study Notes
Clearing CMOS
- Clearing CMOS resets the BIOS/UEFI to default settings.
- Reasons for clearing CMOS:
- Resolving boot issues or system instability caused by incorrect BIOS/UEFI settings.
- Fixing hardware compatibility issues when new components are added.
- Resolving BIOS/UEFI password issues by clearing password protection.
- Clearing configuration errors such as system time and date misconfigurations.
How to Clear CMOS
- Common methods of clearing CMOS:
- Using the Clear CMOS jumper, located on the motherboard and labeled “CLR_CMOS”, “JCMOS” or “CLR”.
- Removing the CMOS battery, a round silver battery similar to a coin, located on the motherboard.
- Using the BIOS/UEFI reset option, accessible through the BIOS/UEFI menu during boot.
Losing CMOS RTC Settings
- The CMOS battery on the motherboard provides power to the CMOS RAM to keep the internal clock running and store settings.
- Error messages indicating CMOS data loss:
- CMOS configuration mismatch.
- CMOS date/time not set.
- BIOS time and settings reset.
- No boot device available.
- CMOS battery state low.
- Reasons for losing CMOS data:
- Pulling and inserting cards.
- Touching the motherboard.
- Dropping something on the motherboard.
- Dirt on the motherboard.
- Faulty power supplies.
- Electrical surges.
BIOS/UEFI Advanced Mode
- Advanced Mode in BIOS/UEFI:
- Provides in-depth access to system configuration and optimization, allowing for comprehensive changes.
- It is intended for experienced users as improper modifications can affect system stability and performance.
- Tabs and features under Advanced Mode (may vary based on motherboard model):
-
Main Tab:
- Displays system hardware information.
- Allows for system language and date/time settings adjustment.
-
Ai Tweaker Tab (or Overclocking Tab):
- Offers CPU and memory overclocking options.
- Provides voltage control for various components.
- Offers XMP profiles for enhanced performance.
-
Advanced Tab:
- Allows detailed configuration of CPU settings, including enabling/disabling cores and virtualization.
- Provides options to manage chipset and SATA configurations.
- Offers USB and integrated peripherals management.
-
Monitor Tab:
- Provides real-time system health data like CPU and motherboard temperatures, fan speeds, and voltages.
- Offers fan control options.
-
Boot Tab:
- Offers advanced settings for configuring boot device priority and bootable devices.
- Provides Secure Boot configuration options.
- Includes additional boot configuration settings such as fast boot, boot logo display, and boot delay adjustments.
-
Security Tab:
- Allows users to configure BIOS and system access passwords.
- Provides TPM (Trusted Platform Module) configuration options for enhanced hardware-based security.
-
Tool Tab:
- Includes Profile Management, BIOS Flash Utility, and Memory Diagnostics tools.
-
Exit Tab:
- Offers options to save and exit, discard changes, restore defaults, and boot overrides.
-
Main Tab:
Trusted Platform Module (TPM)
- TPM is a hardware component designed to enhance computer security.
- Key features of TPM:
- Secure cryptographic functions: Generates, stores, and manages encryption keys.
- Secure storage: Provides safe storage for cryptographic keys, passwords, and digital certificates.
- Platform integrity: Measures and verifies the boot process and system states.
USB Port Security
- Disabling USB ports is common practice in high-security environments to mitigate risks associated with inserting bootable USB drives.
BIOS/UEFI Settings Management
- Care and Feeding of BIOS/UEFI:
- Always document current settings before making changes.
- Only adjust settings that you are familiar with.
- Make incremental changes to identify potential issues.
- Default/Optimized Settings:
- Load Default Settings (or Fail-Safe Defaults): Resets all settings to conservative defaults, prioritizing compatibility and stability over performance.
- OS Optimized Defaults: Configures the system for optimal performance and stability based on the operating system.
