Operating System Setup
If you are installing new system software, or are re-configuring your computer for a different system, make sure you
configure the appropriate OS setting in the BIOS before installing a new operating system (Note: If you have installed
the Windows Vista/Windows 7 operating system with AHCI mode enabled, DO NOT disable AHCI mode or you
will need to reinstall the Windows Vista OS).
1. Start-up the computer and press <F2> to enter the BIOS.
2. Go to the Advanced menu, select “Installed O/S” and make sure the appropriate operating system is selected.
3. Go to the Exit menu and select “Exit Saving Changes” (or press F10 and select “Yes” then press Enter) and
press Enter to exit the BIOS and reboot the computer.

SATA Mode Selection
Make sure that you have selected the appro-
priate SATA Class ID for your hard disk. If
you have installed the Vista/Win 7 O/S with
AHCI or IDE mode selected, do not change
the setting (otherwise you will need to rein-
stall your O/S).
