Network Boot Prompt

This option allows the user to boot from the Network by pressing F12 after the system is turned on. Pressing F12 will override the normal boot sequence. Select “Enabled“ to display the F12 prompt.

Power-On Status

This option controls the display of the memory count, system check points, and beeps when the system is turned on. Select “Enabled” to allow this information to be displayed. Select “Disabled“ which is the default value to turn these off.

Virus Detection

The system has a built-in virus detection program. The virus detection program runs at boot time, and can be enabled or disabled from this field. The default is set to “Disabled“.

Date and Time

From the Configuration/Setup main menu, select the Date and Time option to view or change the system clock from the Date and Time menu. If you want to change the system date, enter the date in the format shown on the screen.

If you change the time, enter the time in 24-hour format (hours, minutes, seconds). For example:

-12 midnight is 00:00:00

-12 noon is 12:00:00

-1 p.m. is 13:00:00

When setting date and time, press the up- or down- arrow key to highlight a field. The date and time are saved as you type it.

System Security

Enhanced Security Enabled/Disabled

Enhanced Security can be Enabled or Disabled only while flashing the system BIOS. Enhanced Security Enabled gives the highest level of protection of system resources by locking the Administrator password and startup sequence in the EEPROM. This level of security may not be desirable in networking environment.
