Study Notes
BIOS Access and Configuration
- BIOS initialization occurs during computer startup
- Access BIOS setup using a key (Delete, function key, or key combination) during startup.
- Hyper-V and VMware Workstation allow BIOS access within virtualization software.
- VirtualBox does not offer BIOS access; consider UEFI BIOS simulators.
- Windows 8, 10, and 11 might not offer a key-press BIOS entry option due to fast startup.
- Fast startup places the system in a hibernated state, not a complete shutdown.
- To bypass fast startup, hold Shift while clicking restart or disable from Settings.
- MSConfig offers an alternative system restart option.
- Interrupt boot process three times to bypass fast startup.
BIOS Configuration Settings
- BIOS configuration changes can lead to boot failures.
- Back up BIOS settings before making changes, using images or taking notes.
- BIOS contains numerous settings impacting hardware functionality.
- Selecting boot sequence (order) of devices (e.g., USB, SSD, hard drive).
- BIOS can disable or enable hardware components, e.g., USB ports.
- USB port disabling is important for security, to prevent unauthorized data transfer.
- The US DoD disabled USB ports due to the SillyFDC worm attack (2008).
- BIOS configuration controls computer hardware and software interaction.
BIOS Fan and Cooling Control
- BIOS can manage system fans (CPU, chassis fans), impacting performance and noise levels.
- Motherboards have integrated fan controllers adjusting airflow based on system temperatures.
- Connect fans directly to motherboard connections.
- Adjust performance-to-quietness balance using power options under intelligent cooling.
BIOS Security and Boot Process
- Secure boot (UEFI specification) verifies the boot process using digital signatures.
- Secure boot protects against malware modifications during system start-up.
- Supports various operating systems (Windows, Linux).
- Require OS digital signatures (public keys) for secure boot.
- BIOS includes fail-safes to prevent unauthorized changes to system settings.
BIOS Access Restriction
- Implement user passwords to restrict BIOS access.
- Supervisor passwords restrict BIOS configuration changes.
- BIOS passwords are separate from operating system passwords, stored in flash memory.
- Resetting BIOS configurations involves clearing CMOS data, commonly through shorting pins.
BIOS and Motherboard Components
- Modern BIOS configurations are stored in motherboard flash memory.
- Removing and reinserting motherboard-battery does not affect BIOS configuration anymore, only the time and date settings.
- Modern systems use flash memory for BIOS configurations, not CMOS.
- Older systems used CMOS.
TPM (Trusted Platform Module)
- TPM cryptographic functionality useful for full-disk encryption.
- TPM stores persistent cryptographic keys.
- Use TPM to digitally sign data and verify its origin.
- Modifying TPM configurations within the BIOS.
- Some organizations use Hardware Security Modules (HSM).
HSM (Hardware Security Module)
- Standalone devices or adapter cards for secure cryptographic key management.
- HSMs provide secure key backups.
- HSMs have hardware-based cryptographic accelerators.
- Lightweight HSMs, like smart cards, are used for personal keys.
