							3-16MS-7366 Mainboard IRQ Resource Setup
Press  to enter the sub-menu and the following screen appears. IRQ 3/4/5/7/9/10/11/14/15
These items specify the bus where the specified IRQ line is used.
The settings determine if AMIBIOS should remove an IRQ from the pool of avail-
able IRQs passed to devices that are configurable by the system BIOS. The
available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must
be removed from the IRQ pool, the end user can use these settings to reserve
the IRQ by assigning an [Reserved] setting to it. Onboard I/O is configured by
AMIBIOS. All IRQs used by onboard I/O are configured as [Available]. If all IRQs
are set to [Reserved], and IRQ 14/15 are allocated to the onboard PCI IDE, IRQ 9
will still be available for PCI and PnP devices.Important
IRQ (Interrupt Request) lines are system resources allocated to I/O devices.
When an I/O device needs to gain attention of the operating system, it sig-
nals this by causing an IRQ to occur. After receiving the signal, when the
operating system is ready, the system will interrupt itself and perform the
service required by the I/O device.7366v1.0-3_ami.p65  2007/10/1, 下午 03:4316 
						

							3-17BIOS Setup Chassis Intrusion
The field enables or disables the feature of recording the chassis intrusion status
and issuing a warning message if the chassis is once opened. To clear the warning
message, set the field to [Reset]. The setting of the field will automatically return to
[Enabled] later. CPU Smart FAN Target
The mainboard provides the Smart Fan function which can control the CPU fan speed
automatically depending on the current temperature to keep it with in a specific range.
You can select a fan target value here. If the current CPU fan temperature reaches to
the target value, the smart fan function will be activated. It provides several sections
to speed up for cooling down automaticlly. PC Health Status CPU/ System Temperature, CPU FAN/ SYS FAN1 Speed, CPU Vcore,
3.3V, 5V, 12V, 5V SB
These items display the current status of all of the monitored hardware devices/
components such as CPU voltage, temperatures and all fans’ speeds.H/W Monitor7366v1.0-3_ami.p65  2007/10/1, 下午 03:4317 
						

							3-18MS-7366 Mainboard Current CPU/ FSB/ DRAM Frequency
These items show the current clocks of CPU and Memory speed. Read-only. Intel EIST
The Enhanced Intel SpeedStep technology allows you to set the performance level of
the microprocessor whether the computer is running on battery or AC power. This
field will appear after you installed the CPU which support speedstep technology. System Clock Mode
item allows you to select the system front side bus clock frequency (in MHz). Advance DRAM Configuration
Press  to enter the sub-menu: Memory Timings
This field has the capacity to automatically detect all of the DRAM timing. If you
set this field to [Manual], the following fields will be selectable.Frequency/Voltage ControlImportant
Change these settings only if you are familiar with the chipset.7366v1.0-3_ami.p65  2007/10/1, 下午 03:4318 
						

							3-19BIOS Setup tCL (CAS Latency)
When the Memory Timings sets to [Manual], the field is adjustable.This con-
trols the CAS latency, which determines the timing delay (in clock cycles) before
SDRAM starts a read command after receiving it. tRCD
When DRAM is refreshed, both rows and columns are addressed separately.
This setup item allows you to determine the timing of the transition from RAS
(row address strobe) to CAS (column address strobe). The less the clock
cycles, the faster the DRAM performance. tRP
When the Memory Timings sets to [Manual], the field is adjustable. This item
controls the number of cycles for Row Address Strobe (RAS) to be allowed to
precharge. If insufficient time is allowed for the RAS to accumulate its charge
before DRAM refresh, refreshing may be incomplete and DRAM may fail to retain
data. This item applies only when synchronous DRAM is installed in the system. tRAS
When the Memory Timings sets to [Manual], the field is adjustable. This setting
determines the time RAS takes to read from and write to a memory cell. Command Per Clock (CMD)
This field controls the SDRAM command rate. Selecting [1T] makes SDRAM
signal controller to run at 1T (T=clock cycles) rate. Selecting [2T] makes SDRAM
signal controller run at 2T rate. tRRD
When the Memory Timings sets to [Manual], the field is adjustable.  Specifies
the active-to-active delay of different banks. tRC
When the Memory Timings sets to [Manual], the field is adjustable. The row
cycle time determines the minimum number of clock cycles a memory row takes
to complete a full cycle, from row activation up to the precharging of the active
row. tWR
When the Memory Timings sets to [Manual], the field is adjustable. Minimum
time interval between end of write data burst and the start of a precharge
command. Allows sense amplifiers to restore data to cells. tWTR
When the Memory Timings sets to [Manual], the field is adjustable. Minimum
time interval between the end of write data burst and the start of a column-read
command. It allows I/O gating to overdrive sense amplifiers before read com-
mand starts.7366v1.0-3_ami.p65  2007/10/1, 下午 03:4319 
						

							3-20MS-7366 Mainboard Adjust PCI-E Frequency
This field allows you to select the PCIE frequency (in MHz). Auto Disable DIMM/PCI Frequency
When set to [Enabled], the system will remove (turn off) clocks from empty DIMM and
PCI slots to minimize the electromagnetic interference (EMI). Memory Voltage
Adjusting the memory voltage can increase the DDR speed. Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes) of the
pulses create EMI (Electromagnetic Interference). The Spread Spectrum function
reduces the EMI generated by modulating the pulses so that the spikes of the pulses
are reduced to flatter curves. If you do not have any EMI problem, leave the setting at
Disabled for optimal system stability and performance. But if you are plagued by EMI,
set to Enabled for EMI reduction. Remember to disable Spread Spectrum if you are
overclocking because even a slight jitter can introduce a temporary boost in clock
speed which may just cause your overclocked processor to lock up.1.If you do not have any EMI problem, leave the setting at [Disabled] for
optimal system stability and performance. But if you are plagued by EMI,
select the value of Spread Spectrum for EMI reduction.
2.The greater the Spread Spectrum value is, the greater the EMI is reduced,
and the system will become less stable. For the most suitable Spread
Spectrum value, please consult your local EMI regulation.
3.Remember to disable Spread Spectrum if you are overclocking because
even a slight jitter can introduce a temporary boost in clock speed which
may just cause your overclocked processor to lock up.Important7366v1.0-3_ami.p65  2007/10/1, 下午 03:4320 
						

							3-21BIOS Setup
The two options on the main menu allow users to restore all of the BIOS settings to
the default Fail-Safe or Optimized values. The Optimized Defaults are the default
values set by the mainboard manufacturer specifically for optimal performance of the
mainboard. The Fail-Safe Defaults are the default values set by the BIOS vendor for
stable system performance.
When you select Load Fail-Safe Defaults, a message as below appears:
Pressing Y loads the BIOS default values for the most stable, minimal system
performance.
When you select Load Optimized Defaults, a message as below appears:
Pressing Y loads the default factory settings for optimal system performance.Load Fail-Safe/ Optimized Defaults7366v1.0-3_ami.p65  2007/10/1, 下午 03:4321 
						

							3-22MS-7366 MainboardBIOS Setting Password
When you select this function, a message as below will appear on the screen:
Type the password, up to six characters in length, and press . The password
typed now will replace any previously set password from CMOS memory. You will
be prompted to confirm the password. Retype the password and press . You
may also press  to abort the selection and not enter a password.
To clear a set password, just press  when you are prompted to enter the
password. A message will show up confirming the password will be disabled. Once
the password is disabled, the system will boot and you can enter Setup without
entering any password.
When a password has been set, you will be prompted to enter it every time you try
to enter Setup. This prevents an unauthorized person from changing any part of your
system configuration.7366v1.0-3_ami.p65  2007/10/1, 下午 03:4322
