  30. Activity—Booting the SystemFig 1.2 Powering on the Computer p. 8 Ch1

  31. Activity—Booting the System Windows XP Professional Startup Sequence: 1. BIOS initiates POST, finds boot device and then loads first physical sector or booting device into memory. 2. Ntldr is loaded and then it loads Ntdetct.com for hardware detection. 3. Hardware configuration selection (if needed). 4. Kernel loading. Ch1

  32. Activity—Booting the System Windows XP Professional Startup Sequence: 5. Determine which Plug and Play devices are installed. 6. Media support files for hard drive and any special video drivers are loaded. 7. Drivers for all services system supports are loaded. 8. Operating system logon process Ch1
