Getting Help
After entering the Setup menu, the first menu you will see is the Main Menu.
Main Menu
The main menu lists the setup functions you can make changes to. You can use the
arrow keys ( ­¯ ) to select the item. The on-line description of the highlighted setup
function is displayed at the bottom of the screen.
Sub-Menu
If you find a right pointer symbol (as shown in the right  view) appears to the left of
certain fields, that means a sub-menu can be launched from this field. A sub-menu
contains additional options for a field parameter. You
can use arrow keys ( --> ) to highlight the field and
press  to call up the sub-menu. Then you can
use the control keys to enter values and  move from
field to field within a sub-menu. If you want to return
to the main menu, just press .

Quick Boot
Setting the item to Enabled allows the system to boot within 5 seconds since it will
skip some check items. Setting options: [Enabled], [Disabled].
Boot Sequence
Press  to enter the sub-menu and the following screen appears:
1st/2nd/3rd Boot Device
The items allow you to set the sequence of boot devices where BIOS attempts
to load the disk operating system.
Boot from Other Device
Setting the option to [Enabled] allows the system to try to boot from other device
if the system fails to boot from the 1st/2nd/3rd boot device.MSI Reminds You...
Available settings for “1st/2nd/3rd Boot Device” vary depending on the
bootable devices you have installed. 
						

							3-9 BIOS SetupHard Disk Boot Priority
Press  to enter the sub-menu and the following screen appears:
In the sub-menu, it shows the hard disks information that was installed in the
system, and you can set the hard disk boot priority.
IOAPIC Function
This field is used to enable or disable the APIC (Advanced Programmable Interrupt
Controller). Due to compliance with PC2001 design guide, the system is able to run in
APIC mode. Enabling APIC mode will expand available IRQ resources for the system.
Settings: [Enabled], [Disabled].
MPS Table Version
This field allows you to select which MPS (Multi-Processor Specification) version to
be used for the operating system. You need to select the MPS version supported by
your operating system. To find out which version to use, consult the vendor of your
operating system. Setting options: [1.4], [1.1].
Boot to OS/2
This allows you to run the OS/2®
 operating system with DRAM larger than 64MB.
When you choose [No], you cannot run the OS/2®
 operating system with DRAM larger
than 64MB.  But it is possible if you choose [Yes]. Setting options: [Yes], [No].

AGP & P2P Bridge Control
Press  to enter the sub-menu and the following screen appears:
AGP Aperture Size
This setting controls just how much system RAM can be allocated to AGP for
video purposes.  The aperture is a portion of the PCI memory address range
dedicated to graphics memory address space. Host cycles that hit the aperture
range are forwarded to the AGP without any translation. The option allows the
selection of an aperture size of 32MB, 64MB, 128MB, 256 MB, 512MB and 1GB.
AGP 2.0 Mode
The item sets an appropriate mode for the installed AGP 2.0 card. Selects [4x]
only if your AGP 2.0 card supports it. Setting options: [1x], [2x], [4x].
AGP Driving Control
This field is used to adjust the AGP driving force. Selecting [Manual] allows you
to select an AGP driving force in AGP Driving Value. It is strongly suggested
to select [Auto] to avoid causing any system error. Setting options: [Manual],
[Auto].
AGP Driving Value
This item specifies an AGP driving force. 
						

							3-11 BIOS SetupAGP Fast Write
This option enables or disables the AGP Fast Write feature. The Fast Write
technology allows the CPU to write directly to the graphics card without passing
anything through the system memory and improves the AGP 4X speed. Select
Enabled only when the installed AGP card supports this function. Setting options:
[Enabled], [Disabled].
AGP Master 1 W/S Read
When [Enabled] is selected, one wait state is inserted in the AGP read cycle.
Setting options: [Enabled], [Disabled].
AGP Master 1 W/S Write
When [Enabled] is selected, writeing to the AGP bus are executed with one wait
state inserted. Setting options: [Enabled], [Disabled].
AGP 3.0 Calibration cycle
This setting disables/enables the AGP auto calibration. Setting options: [Disabled],
[Enabled].
VGA Share Memory Size
The system shares memory to the onboard VGA card. This setting controls the
exact memory size shared to the VGA card. Setting options: [Disabled], [16M],
[32M], [64M].
DRAM Configuration
Press  to enter the sub-menu and the following screen appears:
Timing Mode
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. Setting options:
[Auto], [Manual].
Memclock index value (Mhz)
When it is set to Manual in “Timing Mode”, user can place an artificial memory
clock on the system. Setting options: [100MHz], [133MHz], [166MHz], [200MHz].
CAS# Latency (Tcl)
When the Timing Mode is set to [Manual], the field is adjustable.This controls
the CAS latency, which determines the timing delay (in clock cycles) before
SDRAM starts a read command after receiving it. Setting options: [2.0], [2.5], [3.
0]. [2.0] increases the system performance the most while [3.0] provides the
most stable performance. 
						

							3-12MS-7181 Micro-ATX Mainboard
Min RAS# Active Time (Tras)
When the Timing Mode is set to [Manual], the field is adjustable. This setting
determines the time RAS takes to read from and write to a memory cell. Setting
options: [Auto], [5T~15T].
RAS# to CAS# Delay (Trcd)
When the Timing Mode is set to [Manual], the field is adjustable. 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. Setting options: [Auto], [2T~7T].
Row Precharge Time (Trp)
When the Timing Mode is set 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.
Setting options: [Auto], [2T~7T].
Row to Row delay (Trrd)
When the Timing Mode is set to [Manual], the field is adjustable. Specifies the
active-to-active delay of different banks. Setting options: [Auto], [2T], [3T], [4T].
1T/2T Memory Timing
This setting controls the SDRAM command rate. Selecting [Auto] allows SDRAM
signal controller to run at 1T (T=clock cycles) rate. Selecting [1T] makes SDRAM
signal controller run at 2T rate. 1T is faster than 2T. Setting options: [1T], [2T].
LDT & PCI Bus Control
Press  to enter the sub-menu and the following screen appears:
Upstream / Downstream LDT Bus Width
These two item control the utilized widths of the HyperTransport link.  Setting
options: [8 bit], [16 bit].
LDT Bus Frequency
This item specifies the maximum operating frequency of the links transmitter
clock.  Setting options: [Auto], [800 MHz], [600 MHz], [400 MHz], [200 MHz].
