CAS# Latency
This controls the timing delay (in clock cycles) before SDRAM starts
a read command after receiving it.  Settings: [2], [2.5] (clocks).  [2]
(clocks) increases the system performance the most while [2.5] (clocks)
provides the most stable performance.
RAS# Precharge
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, refresh may
be incomplete...

4.6 Power Management Features
ACPI Standby State
This item specifies the power saving modes for ACPI function. If your operating
system supports ACPI, such as Windows 98SE, Windows ME and Windows
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 hardware
maintains all system context.
[S3/STR]The S3 sleep...

4-15BIOS Setup
Re-Call VGA BIOS at S3 Resuming
Selecting [Enabled] allows BIOS to call VGA BIOS to initialize the VGA card
when system wakes up (resumes) from S3 sleep state. The system resume time
is shortened when you disable the function, but system will need an AGP driver
to initialize the VGA card. Therefore, if the AGP driver of the card does not
support the initialization feature, the display may work abnormally or not func-
tion after resuming from S3.

FDC/LPT/COM Ports, Primary/Secondary Master/Slave IDE
These items specify if the BIOS will monitor the activity of the specified
hardware peripherals or components. If set to [Monitor[, any activity
detected on the specified hardware peripherals or components will wake
up the system or prevent the system from entering the power saving
modes. Settings: [Monitor], [Ignore].

Resume On RTC Alarm
This is used to enable or disable the feature of booting up the system on
a scheduled time/date from the power off (S5) state. Settings: [Enabled],
[Disabled].
RTC Alarm Date/Hour/Minute/Second
If Resume On RTC Alarm is set to [Enabled], the system will automatically
resume (boot up) on a specific date/hour/minute/second specified in these
fields. Available settings for each item are:
Alarm Date01 ~ 31, Every Day
Alarm Hour00 ~ 23
Alarm Minute00 ~ 59
Alarm Second00 ~ 59 

4-18 Chapter 4
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...

4-19BIOS Setup
Init. Graphics Adapter Priority
This setting specifies which VGA card is your primary graphics adapter. Setting
options are:
          [ Internal VGA]The system initializes the onboard VGA device.
[PCI/Int-VGA]        The system initializes the installed PCI VGAcard
first.  If a PCI VGA card is not available, it will
initialize the onboard VGA device.
PCI IDE BusMaster
Set this option to [Enabled] to specify that the IDE controller on the PCI local
bus has bus mastering capability. Setting...

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 used.
The settings determine if BIOS 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 a...

USB Controller
This setting is used to enable/disable the onboard USB controllers.
USB Device Legacy Support
Set to [Enabled] if your need to use any USB 1.1/2.0 device in the operating
system that does not support or have any USB 1.1/2.0 driver installed, such as
DOS and SCO Unix.  Setting options: [Disabled], [Enabled].
On-Chip IDE Configuration
Press  to enter the sub-menu and the following screen appears: 4.8 Integrated Peripherals 

4-22 Chapter 4
On-Chip ATA(s) Operate Mode
This setting allows you to determine how the RAID controller on the
south bridge is going to switch to SATA controller. [Legacy Mode] means
you may use the traditional 14 and 15 IRQs, while [Native Mode] means
you may use all the available IRQs.
Legacy  Mode:
--- In this mode, system BIOS just assign the traditional 14 and 15 IRQs to
use for HDD.
--- Older  OSs  that do not support switch to Native Mode (DOS, Win2K,
Win98/ME...) should set SATA and PATA to...
