Chapter 7: BIOS

Change (Serial Port 1 / Serial Port 2) Settings
This option specifi es the base I/O port address and the Interrupt Request
address of Serial Port 1 and 2. Select Auto to let the BIOS automatically
assign the base I/O and IRQ address.
The options for Serial Port 1 are Auto, (IO=3F8h; IRQ=4), (IO=3F8h;
IRQ=3, 4, 5, 6, 7, 9, 10, 11, 12), (IO=2F8h; IRQ=3, 4, 5, 6, 7, 9, 10, 11,
12), (IO=3E8h; IRQ=3, 4, 5, 6, 7, 9, 10, 11, 12) and (IO=2E8h; IRQ=3,
4, 5, 6, 7, 9, 10, 11, 12).
The options for Serial Port 2 are Auto, (IO=2F8h; IRQ=3), (IO=3F8h;
IRQ=3, 4, 5, 6, 7, 9, 10, 11, 12), (IO=2F8h; IRQ=3, 4, 5, 6, 7, 9, 10, 11,
12), (IO=3E8h; IRQ=3, 4, 5, 6, 7, 9, 10, 11, 12) and (IO=2E8h; IRQ=3,
4, 5, 6, 7, 9, 10, 11, 12).

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 confi guration 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 confi gurations. The options are Full Speed
(@100% of PWM Cycle) and Standard (@50% of PWM Cycle).
The following items will be displayed:
• CPU Temperature (PECI)
• Front Side Sys. (System) Temperature
• Rear Side Sys. (System) Temperature
• PCH Temperature
• Fan1 Speed/Fan2 Speed/Fan3 Speed/Fan4 Speed/Fan5 Speed
• VCORE
• 12V
