Asus P55SP4 - Manual (Page 7)

P/I-P55SP4 User's Manual
Since we are assuming that your mainboard is already installed
in a system, it was most likely set up by your system dealer accord­
ing to the design specifications of your computer. This could mean
that your mainboard's current settings are not the same as the de­
faults shown in this manual. Your system manual may have addi­
tional information on how the mainboard should be set up.
If you want to change the existing configuration, consult all of
your system documentation. Also be certain that opening up and
working on the system yourself won't violate your system warranty.
Most system vendors do allow you to open the system to install ex­
pansion cards or additional peripheral equipment.
This manual provides all the information you need to upgrade
or change the setup of the board. If you don't feel confident of your
ability to work on the computer yourself, ask your dealer or a quali­
fied technician to do it for you.
