Study Notes
Boot Process and BIOS
- POST stands for Power-On Self-Test, which is a process that occurs during computer booting.
- The BIOS (Basic Input/Output System) chip contains a small program that controls communication between the operating system and hardware.
- The motherboard manual or online documentation should be consulted to obtain beep codes for a specific computer's motherboard.
Troubleshooting
- Removing all RAM modules and powering on the computer during installation helps to identify if the issue is related to RAM.
- If a device is malfunctioning during the power-on self-test (POST), the boot process will halt and an error message or beep code will be displayed.
BIOS and UEFI
- BIOS stands for Basic Input/Output System in the context of computer hardware.
- The role of the BIOS in a computer motherboard is to control the communication between the operating system and hardware.
- UEFI (Unified Extensible Firmware Interface) is a successor to BIOS, providing a more modern and flexible way of handling computer booting and configuration.
