Legacy USB support operates as follows:
1. When you apply power to the computer, legacy support is disabled.
2. POST begins.
3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to
enter and configure the BIOS Setup program and the maintenance menu.
4. POST completes.
5. The operating system loads. While the operating system is loading, USB keyboards
and mice are recognized and may be used to configure the operating system.
After the operating system loads the USB drivers, all legacy and non-legacy USB
devices are recognized by the operating system, and Legacy USB support from the
BIOS is no longer used.
To install an operating system that supports USB, follow the operating system's
installation instructions.

is not a bootable CD in the CD-ROM drive, the system attempts to boot from the next
defined drive. Refer to
to change this setting.

Network Boot
A network can be selected as a boot device provided you have plugged in the PCI
Express* Intel gigabit NIC. This selection allows booting from a network add-in card
with a remote boot ROM installed.
