First-Time DIY System Builder
Welcome to the DIY world! Building your own computer system is not as diffi-
cult as you may think. To make your first computer DIY experience successful,
right from the start, we have designed the 3.1 Hardware Installation section
in a step-by-step fashion for all the first-time DIY system builders. Prior to instal-
lation, we also suggest you to read the whole manual carefully to gain a com-
plete understanding of your new Shuttle AB49/AB49N mainboard.
Experienced DIY User
Congratulate on your purchase of the Shuttle AB49/AB49N mainboard. You
will find that installing your new Shuttle AB49/AB49N mainboard is just easy.
Bundled with an array of onboard functions, the highly-integrated AB49/AB49N
mainboard provides you with a total solution to build the most stable and reli-
able system. Refer to sections 3.2 Jumper Settings and Chapter 4 Drivers/
Software Utilities to find out how to get the best out of your new mainboard.
Chapter 5 BIOS Setup also contains the relevant information on how to tune
up your system to achieve higher performance.
System Integrator
You have wisely chosen Shuttle AB49/AB49N to construct your system.
Shuttle AB49/AB49N incorporates all the state-of-the-art technology of the
845PE (GMCH) chipset from Intel. It integrates the most advanced functions
you can find to date in a compact ATX board.
This manual is all-purpose for two kinds of mainboards: AB49 and
AB49N. The main difference between them is that AB49N is equipped
with an onboard LAN. In the manual, if there are some standards, charac-
teristics, equipment, or software adopted only by AB49N, it will be high-
lighted in brackets.
