S1 (OS Control) - Enables system wake up from S1 (default).
S5 (OS Control) - Enables system wake up from S1/S3/S4/S5.
Force Enable - Wake up support is always enabled regardless whether
it is disabled in the O/S.
Force Disable - Wake up support is always disabled regardless whether
it is enabled in the O/S.
ITE LPC I/O - IT8760
Serial Port 3 / Serial Port 4
Select Enabled to enable the onboard serial port. The options are Enabled
and Disabled.
Serial Port 3 / Serial Port 4 Settings
This option species the base I/O port address and the Interrupt Request
address of Serial Port 1 ~ 2. Select Auto to let the BIOS automatically assign
the base I/O and IRQ address.
The options for Serial Port 3 are Auto, (IO=3E8h; IRQ=11), (IO=3F8h; IRQ=3,
4, 10, 11), (IO=2F8h; IRQ=3, 4, 10, 11), (IO=3E8h; IRQ=3, 4, 10, 11) and
(IO=2E8h; IRQ=3, 4, 10, 11).
The options for Serial Port 4 are Auto, (IO=2E8h; IRQ=10), (IO=3F8h; IRQ=3,
4, 10, 11), (IO=2F8h; IRQ=3, 4, 10, 11), (IO=3E8h; IRQ=3, 4, 10, 11) and
(IO=2E8h; IRQ=3, 4, 10, 11).
Hardware Health Conguration
Fan Speed Control Mode
This feature allows the user to decide how the system controls the speeds of the
onboard fans. The CPU temperature and the fan speed are correlative. When the
CPU on-die temperature increases, the fan speed will also increase for effective
system cooling. Select "Full Speed" to allow the onboard fans to run at full speed
(of 100% Pulse Width Modulation Duty Cycle) for maximum cooling. This setting
is recommended for special system conguration or debugging. Select "Standard"
for the onboard fans to run at 50% of the Initial PWM Cycle in order to balance the
needs between system cooling and power saving. This setting is recommended for
regular systems with normal hardware congurations. The options are Full Speed
(@100% of PWM Cycle), and Standard (@50% of PWM Cycle).
