IOS Setup
In most cases, the USC-250 device will have been setup and configured by the
dealer or systems integrator prior to delivery. However, some of the BIOS settings
may need adjustment to set the system configuration data, such as the current date
and time, or type of hard drive installed. The setup program is stored in read-only
memory (ROM) and can be accessed when activating or resetting the computer, or
by pressing <Delete> upon boot up.
3.1 Introduction
With the AMI BIOS Setup Utility, users can modify BIOS settings to control the com-
puter functions. The BIOS Setup Utility features a number of menus with configurable
items for adjusting the settings. The basic navigation of the BIOS menu screens is
described in this chapter.
3.2 BIOS Setup
The BIOS configuration settings are saved in Flash memory on the motherboard.
When the power is turned off, the battery on the board supplies the necessary power
to preserve the Flash memory. To access the BIOS CMOS Setup Utility, after system
bootup, press the <Del> or <Esc> button during the BIOS POST (power-on Self test).
