Certain options require that you reboot the computer for new settings to take effect.
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 and enable/disable devices using the Boot Order page of system setup.
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 start-up files. When the computer
finds the files, it stops searching and starts the operating system.
To control the boot devices, select (highlight) a device by pressing the down-arrow or up-arrow key, and then enable or disable the device or change its order
in the list.
l
To enable or disable a device, highlight the item and press the space bar. Enabled items appear as white and display a small triangle to the left;

l

Boot sequence changes take effect as soon as you save the changes and exit system setup.

Changing Printer Modes
Set the Parallel Mode option according to the type of printer or device connected to the parallel connector. To determine the correct mode to use, see the
