The first authoritative guide to optimizing your PC's BIOS

Your PC's BIOS enables your software and hardware to work together. But they can work together better—way better. If you want the best possible PC performance and stability, this book shows you exactly what to tweak, and how to tweak it.

Until now, most BIOS information was terse, incomprehensible...practically useless. Not anymore! Breaking Through the BIOS Barrier: The Definitive BIOS Optimization Guide for PCs reveals the secrets behind 200 of today's most important BIOS settings. You won't just learn what they're for: You'll learn exactly how to use them in both optimization and troubleshooting.

Author Adrian Wong created the Web's #1 BIOS resource: the BIOS Optimization Guide at Adrian's Rojak Pot. Nobody knows more about your PC's BIOS... and no other book delivers this much accurate, usable information!

Learn about:

  • The BIOS—what it really is, what it does, and how to optimize it safely
  • All the different BIOS features and how to optimize them
  • Optimizing your system memory, CPU, PCI bus, AGP port, USB ports, hard disks, and more
  • Customizing the boot sequence and accelerating the bootup process
  • Maximizing system security and stability
  • Restoring your BIOS in any emergency, step by step
  • Myths and misconceptions surrounding the BIOS—and the truth

If you're a gamer, PC enthusiast, or tech support professional... if you care about PC performance and reliability... if you're passionate about what goes on under the hood... this is the book you've been searching for!
