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
