Setup Configuration Utility (SCU) 5-13
Boot Menu
The Boot menu sets the sequence of the devices to be searched for the
operating system.
Boot Sequence
Sets the first, second, third, and fourth boot device. The system will try to
boot from the first device but if it is not available, will try the next boot
device. If you set the first boot device to LAN Boot, the system will boot
from the LAN server first. The options are Hard Disk Drive, CD-ROM
Drive, Floppy Disk Drive, and LAN Boot.
NOTE: If you set all booting options to the same device, then the computer will try to
boot from that device only.
