Study Notes

Observing the Boot Routine

Turn on all peripherals and the computer to observe the system for any indications of problems
Check the power supply fan and ensure it runs normally
Observe the Num Lock, Caps Lock, and Scroll Lock indicators on the keyboard, which should flash momentarily and then settle on the Num Lock indicator

Beep Codes and System Error Messages

Beep codes are a series of beeps indicating an error condition
System error messages provide information on problems or status

Device Drivers

Device drivers are software programs that control specific hardware devices attached to a computer
They are essential for a computer to work properly
Device drivers provide the means for a computer to interact with hardware devices

Types of Device Drivers

Kernel-mode Device Drivers:
- Include BIOS, motherboard, processor, and other hardware drivers that load with the operating system
- Examples include BIOS and motherboard drivers
User-mode Device Drivers:
- Include drivers for devices brought by the user, such as plug and play devices
Hardware Drivers:
- Designed to allow pieces of computer hardware to function on a computer
- Examples include video cards, sound cards, and network cards
Virtual Device Drivers:
- Emulate a piece of hardware, tricking the computer into thinking it is reading from actual hardware
- Example: reading .iso files without an actual disc

Updating Device Drivers in Windows

Driver updates are automatically downloaded and installed through Windows Update
Manual updates can be done through the Device Manager
Steps to update a device driver include searching automatically for updated driver software and selecting Update Driver
