5-12     Chapter 5:  BIOS Setup configuration
Stop CPU clock in sleep state
When set to Yes, the system internal clock stops, along with 
other internal devices, when the computer enters the sleep 
state. When set to No, the system internal clock continues to 
run when the system is in the sleep state. This item turns 
gray and is non-configurable when the System Sleep Timer 
is off. The default setting is Yes.
Power switch < 4 sec.
When set to Suspend, this parameter adds the suspend 
function to the system power button on the front panel. The 
suspend function allows you to put the system into suspend 
mode by pressing the power button for less than four 
seconds while the system is on. When this parameter is set 
to Power off, the power button simply turns the system 
power on or off. This parameter is set to Power off by default.
Modem Wake-Up on Ring
This parameter allows you to enable or disable the Modem 
Wake-Up on Ring feature. If the computer is in suspend and 
this parameter is enabled, the computer will automatically 
resume the normal power on mode when it receives an 
incoming call. When disabled, the system does not return to 
the “normal on” state even if there is an incoming modem 
access. The default setting is Enabled.
Startup options
From the Setup main menu, select 
Startup Options 
to view 
or change startup configuration settings. The Startup 
Options menu appears. This menu identifies the startup 
devices.
Fast POST mode
When set to Auto, which is the default, this parameter allows 
the system to boot faster by skipping some power on self-
test (POST) routines.
Silent boot
This parameter enables or disables the silent boot function. 
When set to Enabled, which is the default, BIOS is in 
graphical mode and displays the IBM logo while booting. If 
an error occurs while booting, the system automatically 
switches to text mode.
Even if your setting is Enabled, you may also switch to the 
text mode while booting by pressing 
F9
 after you see the 
message “Press <F1> to go to the Setup Utility”.
When set to Disabled, BIOS is in the conventional text mode 
where you see the system initialization details on the screen.
