							3-18MS-6728 ATX MainboardPNP/PCI Configurations
This section describes configuring the PCI bus system and PnP (Plug
& Play) feature.  PCI, or Peripheral Component Interconnect, is a system which
allows I/O devices to operate at speeds nearing the speed the CPU itself uses
when communicating with its special components.  This section covers some
very technical items and it is strongly recommended that only experienced
users should make any changes to the default settings.
Clear NVRAM
The ESCD (Extended System Configuration Data) NVRAM (Non-volatile
Random Access Memory) is where the BIOS stores resource information for
both PNP and non-PNP devices in a bit string format. When the item is set to
Yes, the system will reset ESCD NVRAM right after the system is booted up
and then set the setting of the item back to No automatically.
PCI Latency Timer (PCI Clocks)
This item controls how long each PCI device can hold the bus before another
takes over. When set to higher values, every PCI device can conduct
transactions for a longer time and thus improve the effective PCI bandwidth.
For better PCI performance, you should set the item to higher values. Settings
are: 32, 64, 96, 128, 160, 192, 224, 248. 
						

							3-19 BIOS SetupIRQ 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 available 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 ISA/EISA setting to it.Init. Graphics Adapter Priority
This setting specifies which VGA card is your primary graphics adapter. Setting
options are:
AGP/PCIThe system initializes the installed AGP card
first.  If an AGP card is not available, it will initial-
ize the PCI VGA card.
PCI/AGPThe system initializes the installed PCI VGA card
first.  If a PCI VGA card is not available, it will
initialize the AGP card.
PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the PCI local
bus has bus mastering capability. Setting options: Disabled, Enabled.
PCI Slot1 IRQ Priority, PCI Slot2/5 IRQ Priority, PCI Slot3 IRQ Priority,
PCI Slot4 IRQ Priority
These items specify the IRQ line for each PCI slot. Setting options: 3, 4, 5, 7, 9,
10, 11, Auto. Selecting Auto allows BIOS to automatically determine the IRQ
line for each PCI slot.
Set IRQs to PCI or ISA
Press  to enter the sub-menu and the following screen appears: 
						

							3-20MS-6728 ATX MainboardOnboard I/O is configured by AMIBIOS. All IRQs used by onboard I/O
are configured as PCI/PnP. If all IRQs are set to ISA/EISA, and IRQ 14/15
are allocated to the onboard PCI IDE, IRQ 9 will still be available for PCI
and PnP devices. Available settings: ISA/EISA and PCI/PnP.
Set DMAs to PnP or ISA
Press  to enter the sub-menu and the following screen appears:
DMA Channel 0/1/3/5/6/7
These items specify the bus that the system DMA (Direct Memory
Access) channel is using.
The settings determine if AMIBIOS should remove a DMA from the
available DMAs passed to devices that are configurable by the system
BIOS. The available DMA pool is determined by reading the ESCD NVRAM.
If more DMAs must be removed from the pool, the end user can reserve
the DMA by assigning an ISA/EISA setting to it. 
						

							3-21 BIOS SetupIntegrated Peripherals
Please note that the options showed on your BIOS might be different
depending on the motherboard you buy.
USB Controller
This setting is used to enable/disable the onboard USB controllers.
USB Device Legacy Support
Set to All Device if you need to use any the USB 1.1/2.0 device in the operat-
ing system that does not support or have any USB 1.1/2.0 driver installed,
such as DOS and SCO Unix. Set to Disabled only if you do not want to use
any USB device. Set to Keyboard+Mouse if you only want to use keyboard
and mouse. Setting options: Disabled, Keyboard+Mouse, All Device.

If you wish to use S-ATA devices on your mainboard while the
ATA devices connected to the IDE1 and IDE2 are also available,
you MUST have Windows XP/2000 operation system in your
computer, and configure the settings listed as following when
you enter the BIOS setup program.
However, if you are using Windows 98/Me, please also refer to
the following settings for the best performance.

This item is used to enable or disable the onboard AC’97 (Audio Codec’97)
feature.  Selecting Auto allows the mainboard to detect whether an audio de-
vice is used.  If an audio device is detected, the onboard AC’97 controller will
be enabled; if not, the controller is disabled.  Disable the function if you want to
use other controller cards to connect an audio device.  Settings: Disabled and
Auto. On-Chip IDE

Parallel Port IRQ
When Onboard Parallel Port is set to Auto, the item shows Auto
indicating that BIOS determines the IRQ for the parallel port
automatically.
Parallel Port DMA Channel
This feature needs to be configured only when Parallel Port Mode is
set to the ECP mode. When Parallel Port is set to Auto, the field will
show Auto indicating that BIOS automatically determines the DMA
channel for the parallel port. 
						

							3-26MS-6728 ATX MainboardPC Health Status
This section shows the status of your CPU, fan, overall system status,
etc.  Monitor function is available only if there is hardware monitoring mecha-
nism onboard.
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.  Settings: Enabled, Reset, Disabled.

components such as CPU voltages, temperatures and all fans’ speeds. 
						

							3-27 BIOS SetupPerformance Mode
This item allows you to control the MAT (memory acceleration technology)
function of CPU. MAT is MSITM
’s exclusive technology, specializing in opti-
mizing the data transfer rate among CPU, north bridge chip and memory, and
also in procuring better memory performance and bandwidth up to 10%. Select-
ing Fast will enable MAT. Please be noted that not every memory is compatible
with MAT. If the system fail to reboot for four times, the BIOS will be restored
to the Default value (Normal). Setting options: Normal, Fast, Turbo (MAT),
Ultra Turbo (MAT).MSI Reminds You...
1.Even though MAT is easy to use, it doesnt mean theres no
risk at all. We recommend you to check if your memory is
able to bear MAT setting or not before deciding to always
use it. If your system will be unstable or reboot incidentally
after switching to Fast, please switch back to Normal.
Moreover, if you want to conduct FSB overclocking, you
should set MAT as Normal.Use this menu to specify your settings for frequency/voltage control. Frequency/Voltage Control
