Study Notes
Computer Startup Process: BIOS and UEFI
- BIOS (Basic Input/Output System): Starts when the power button is pressed.
- Firmware: Software that initializes the system (often stored in flash memory).
- Initialization: BIOS initializes CPU and memory.
- POST (Power-On Self-Test): Checks for essential components (memory, CPU, video, input devices). If everything is found, it proceeds to load the boot drive.
- Boot Drive: BIOS identifies the configured boot drive.
- Boot Loader: BIOS searches for a boot loader on the drive to begin the operating system load.
BIOS Types: Legacy vs. UEFI
- Legacy BIOS: Older type, text-based, and has been around for about 25 years.
- UEFI (Unified Extensible Firmware Interface): Modern, standardized BIOS used in most current computers. Created by Intel's EFI standard.
- Standardization: UEFI allows multiple manufacturers to create BIOSes with consistent functionalities.
- Modern Capabilities: UEFI BIOS allows advanced features and easier upgrades. Modern operating systems can interact better with the hardware.
- Examples: UEFI BIOS allows configuration changes (like adding passwords) and installing additional drivers for new hardware.
UEFI BIOS Features
- Sections: UEFI BIOS menus often have sections like "Main", "Security", "Advanced" and "UEFI Drivers".
- Main Section: Allows to view system details (serial numbers, hardware configuration), adjust date/time, run diagnostics.
- Security Section: Enables password settings for user accounts.
- Advanced Section: Configures boot options.
- UEFI Driver Section: Installs drivers for connected hardware (network interfaces, storage devices).
