shown on the screen.
If you change the time, enter the time in 24-hour

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.
