Power Management Setup
Sleep State
This item specifies the power saving modes for ACPI function. If your operating
system supports ACPI, such as Windows 98SE/ME/2000/XP, you can choose to
enter the Standby mode in S1(POS) or S3(STR) fashion through the setting of this
field. Options are:
[S1 (POS)] The S1 sleep mode is a low power state. In this state,
no system context is lost (CPU or chipset) and hard-
ware maintains all system context.
[S3 (STR)] The S3 sleep mode is a lower power state where the
in formation of system configuration and open appli-
cations/files is saved to main memory that remains
powered while most other hardware components turn
off to save energy. The information stored in memory
will be used to restore the system when a “wake up”
event occurs.
[Auto]BIOS determines the best mode automatically.
Power Management
This item is used to select the degree (or type) of power saving and is related to the
HDD Power Down item. There are three options for power management:
[Min Saving] Minimum Power Management. Suspend Mode=1 Hour
[Max Saving]Maximum Power Management. Suspend Mode=1 Min
[User Define] Allows end users to configure each mode separately.
MSI Reminds You...
S3-related functions described in this section are available only when
your BIOS supports S3 sleep mode.

PNP/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 communi-
cating 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.
Resource Controlled By
The Award Plug and Play BIOS has the capacity to automatically configure all of the
boot and Plug and Play compatible devices. However, this capability means abso-
lutely nothing unless you are using a Plug and Play operating system such as Win-
dows
® 95/98. If you set this field to [Manual], choose specific resources by going into
each of the sub menu that follows this field (a sub menu is preceded by a “`”). The
settings are: [Auto (ESCD)], [Manual].
IRQ Resources
The items are adjustable only when Resources Controlled By is set to [Manual].
Press  and you will enter the sub-menu of the items. IRQ Resources list IRQ
3/4/5/7/9/10/11/12/14/15 for users to set each IRQ a type depending on the type of
device using the IRQ. Settings are:
[PCI Device]For Plug & Play compatible devices designed for PCI bus
architecture.
[Reserved] The IRQ will be reserved for further request. 
						

							3-21 BIOS Setup
PCI/VGA  Palette  Snoop
When set to [Enabled], multiple VGA devices operating on different buses can handle
data from the CPU on each set of palette registers on every video device. Bit 5 of the
command register in the PCI device configuration space is the VGA Palette Snoop bit
(0 is disabled). For example, if there are two VGA devices in the computer (one PCI
and one ISA) and the:
The setting must be set to [Enabled] if any ISA bus adapter in the system requires
VGA palette snooping.
MSI Reminds You...
IRQ (Interrupt Request) lines are system resources allocated to I/O
devices. When an I/O device needs to gain the attention of the operating
system, it signals 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.
 VGA Palette Snoop
 Bit SettingAction
[Disabled]Data read or written by the CPU is only directed to the PCI
VGA device’s palette registers.
[Enabled]Data read or written by the CPU is directed to both the PCI
VGA device’s palette registers and the ISA VGA device’s
palette registers, permitting the palette registers of both
VGA devices to be identica
