Changing the Boot Sequence
The boot sequence, or boot order, tells the computer where to look to find the software needed to start the operating system. You can control the boot
sequence using the Boot Order page of the system setup program.
The Boot Order page displays a general list of the bootable devices that may be installed in your computer, including but not limited to the following:
l Diskette Drive
l Modular bay HDD
l Internal HDD
l CD/DVD/CD-RW drive
During the boot routine, the computer starts at the top of the list and scans each enabled device for the operating system startup files. When the computer
finds the files, it stops searching and starts the operating system.
To control the boot sequence, you can select (highlight) devices using the the and keys and then enable or disable them or change their order in
the list.
l To enable or disable a device, highlight the item and press . Enabled items appear as white and display a small triangle to the left;
disabled items appear blue or dimmed without a triangle.
l To reorder a device in the list, highlight the device and then press or (not case-sensitive) to move the highlighted device up or down.
Boot sequence changes take effect as soon as you save the changes and exit the system setup program.
