							3-7 BIOS SetupDevice/ Vender/ Size
It will showing the device information that you connected to the IDE/SATA con-
nector .
LBA/Large Mode
This allows you to enable or disable the LBA Mode. Setting to Auto enables LBA
mode if the device supports it and the devices is not already formatted with LBA
mode disabled. Setting options: [Auto], [Disabled].
DMA Mode
Select DMA Mode.
Hard Disk S.M.A.R.T.
This allows you to activate the S.M.A.R.T. (Self-Monitoring Analysis & Reporting
Technology) capability for the hard disks. S.M.A.R.T is a utility that monitors your
disk status to predict hard disk failure. This gives you an opportunity to move
data from a hard disk that is going to fail to a safe place before the hard disk
becomes offline. Setting options: [Auto], [Enabled], [Disabled].
Floppy A
This item allows you to set the type of floppy drives installed. Available options:
[None], [360K, 5.25 in.], [1.2M, 5.25 in.], [720K, 3.5 in.], [1.44M, 3.5 in.], [2.88M, 3.5 in.].
Halt On
The setting determines whether the system will stop if an error is detected at boot.
Available options are:
[No Errors]The system doesn’t stop for any detected error.
[All, But Keyboard]The system doesn’t stop for a keyboard error. 
						

							3-8MS-7210 Micro-ATX MainboardSystem Information
Press  to enter the sub-menu and the following screen appears:
Total System Memory/ BIOS Version/ CPU Information
The items show the CPU information, BIOS version and memory status of your
system (read only). 
						

							3-9 BIOS SetupAdvanced BIOS Features
Quick Boot
Select Enabled to reduce the amount of time required to run the power-on self-test
(POST). A quick POST skips certain steps. We recommend that you normally disable
quick POST. It is better to find a problem during POST than lose data during your work.
Setting options: [Enabled], [Disabled].
Boot Up Num-Lock LED
This setting is to set the Num Lock status when the system is powered on. Setting to
[On] will turn on the Num Lock key when the system is powered on. Setting to [Off]
will allow users to use the arrow keys on the numeric keypad. Setting options: [On],
[Off].
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].
Hyper-Threading Technology
The processor uses Hyper-Threading technology to increase transaction rates and
reduces end-user response times. The technology treats the two cores inside the
processor as two logical processors that can execute instructions simultaneously.
In this way, the system performance is highly improved. If you disable the function,
the processor will use only one core to execute the instructions. Please disable
this item if your operating system doesn’t support HT Function, or
unreliability and instability may occur. Setting options: [Enabled], [Disabled]. 
						

							3-10MS-7210 Micro-ATX Mainboard
Execute Disable Bit
Execute Disable Bit is designed for memory buffer overflow protection, it can prevent
viruses from proliferating. Setting options: [Enabled], [Disabled].
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.
Setting options: [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].
Full Screen LOGO Show
This item enables you to show the company logo on the bootup screen. Settings are:
[Enabled]Shows a still image (logo) on the full screen at boot.
[Disabled]Shows the POST messages at boot.
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. 
						

							3-11 BIOS SetupAdvanced Chipset Features
Configure DRAM Timing by SPD
Selects whether DRAM timing is controlled by the SPD (Serial Presence Detect)
EEPROM on the DRAM module. Setting to [Auto] enables DRAM timings and the fol-
lowing related items to be determined by BIOS based on the configurations on the
SPD. Selecting [Manual] allows users to configure the DRAM timings and the follow-
ing related items manually. Setting options: [Manual], [Auto].
DRAM CAS# Latency
The field controls the CAS latency, which determines the timing delay before SDRAM
starts a read command after receiving it. Setting options: [By SPD], [2.5T], [2T]. [2T]
increases system performance while 2.5T provides more stable system performance.
Setting to By SPD enables DRAM CAS# Latency automatically to be determined by
BIOS based on the configurations on the SPD (Serial Presence Detect) EEPROM on
the DRAM module.
DRAM RAS# to CAS# Delay
This field allows you to set the number of cycles for a timing delay between the CAS
and RAS strobe signals, used when DRAM is written to, read from or refreshed.
Fast speed offers faster performance while slow speed offers more stable
performance.  Setting options: [6 DRAM Clocks], [5 DRAM Clocks], [4 DRAM Clocks].MSI Reminds You...
Change these settings only if you are familiar with the chipset.
