Hardware Setup
Central Processing Unit: CPU
The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™
processors in the 462 pin package. The mainboard uses a CPU socket called
Socket-462 for easy CPU installation. When you are installing the CPU, make
sure the CPU has a heat sink and a cooling fan attached on the top to
prevent overheating. If you do not find the heat sink and cooling fan, contact
your dealer to purchase and install them before turning on the computer.

Thermal Issue for CPU
AMD Athlon™/Athlon™ XP/Duron™ processor with a speed
of 600MHz and above requires LARGER heatsink and fan.
You also need to add thermal grease between the CPU and
heatsink to improve heat dissipation. Then, make sure that the
CPU and heatsink are securely fastened and in good contact
!
WARNING!

Memory
The mainboard provides 3 slots for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) modules and supports the memory size up
to 3GB. You can install PC3200/DDR400, PC2700/DDR333, PC2100/
DDR266 or PC1600/DDR200 modules on the DDR DIMM slots (DDR 1~3).

Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM modules
rather than 168-pin DIMM modules used by SDR SDRAM. High memory
bandwidth makes DDR an ideal solution for high performance PC, workstations
and servers.

(clocks). 2 (clocks) increases the system performance the most while 3
(clocks) provides the most stable performance.
Row Precharge Time
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. Available settings:
Auto, 2, 3, 4, 5.
RAS Pulse Width
This setting allows you to select the number of clock cycles allotted
for the RAS pulse width, according to DRAM specifications. The less
the clock cycles, the faster the DRAM performance. Settings: Auto, 6,
7, 8, 9.
RAS to CAS Delay
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, 2, 3, 4, 5.
Write Recovery Cycle
You may set the write recovery cycle of DRAM. The less the clock
cycles, the less time the DRAM recovery cycle writes. Setting options:
Auto, 1T, 2T.

SDRAM Burst Length
This setting allows you to set the size of Burst-Length for DRAM. Bursting
feature is a technique that DRAM itself predicts the address of the next
memory location to be accessed after the first address is accessed. To
use the feature, you need to define the burst length, which is the actual
length of burst plus the starting address and allows internal address
counter to properly generate the next memory location. The bigger the
size, the faster the DRAM performance. Settings: 4 QW, 8 QW.
SDRAM1TCommand
This setting controls the SDRAM command rate. Selecting Enabled

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 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.
Plug and Play Aware O/S
When set to Yes, BIOS will only initialize the PnP cards used for booting (VGA,
IDE, SCSI). The rest of the cards will be initialized by the PnP operating system
like Windows® 98, 2000 or ME. When set to No, BIOS will initialize all the PnP
cards. Select Yes if the operating system is Plug & Play.
ClearNVRAM
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.

problem, leave the setting at Disabled for optimal system stability and
performance. But if you are plagued by EMI, select one of the options for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking
because even a slight jitter can introduce a temporary boost in clock speed
which may just cause your overclocked processor to lock up. Available options:

The option is for power or overclocking users only. Use of high
performance defaults will tighten most timings to increase the
system performance. Therefore, a high-end system configuration
is a must, which means you need high-quality VGA adapter,
RAM and so on. We don’t recommend that users should apply
the high performance defaults in their regular systems.
Otherwise, the system may become unstable or even crash. If the
system crashes or hangs after enabling the feature, please CLEAR
CMOS DATA to resolve the problem. For more information, refer

Introduction
This section gives a brief introduction on the RAID-related background
knowledge and a brief introduction on VIA SATA RAID Host Controller. For
users wishing to install their VIA SATA RAID driver and RAID software,
proceed to Driver and RAID Software Installation section.
RAID Basics
RAID (Redundant Array of Independent Disks) is a method of combining
two or more hard disk drives into one logical unit. The advantage of an Array
is to provide better performance or data fault tolerance. Fault tolerance is
achieved through data redundant operation, where if one drives fails, a mirrored
copy of the data can be found on another drive. This can prevent data loss if
the operating system fails or hangs. The individual disk drives in an array are
called “members”. The configuration information of each member is recorded
in the “reserved sector” that identifies the drive as a member. All disk members
in a formed disk array are recognized as a single physical drive to the operating
system.
Hard disk drives can be combined together through a few different
methods. The different methods are referred to as different RAID levels.
Different RAID levels represent different performance levels, security levels
and implementation costs. The RAID levels which the VIA VT8237 SATA
RAID Host Controller supports are RAID 0 and RAID 1. The table below
briefly introduced these RAID levels.

VIA VT8237 Serial ATA RAID Introduction
RAID 0 (Striping)
RAID 0 reads and writes sectors of data interleaved between multiple
drives. If any disk member fails, it affects the entire array. The disk array data
capacity is equal to the number of drive members times the capacity of the
smallest member. The striping block size can be set from 4KB to 64KB. RAID
0 does not support fault tolerance.
RAID 1 (Mirroring)
RAID 1 writes duplicate data onto a pair of drives and reads both sets of
data in parallel. If one of the mirrored drives suffers a mechanical failure or
does not respond, the remaining drive will continue to function. Due to
redundancy, the drive capacity of the array is the capacity of the smallest
drive. Under a RAID 1 setup, an extra drive called the .spare drive. can be
attached. Such a drive will be activated to replace a failed drive that is part of
a mirrored array. Due to the fault tolerance, if any RAID 1 drive fails, data
access will not be affected as long as there are other working drives in the
array.

The “Channel”, “Drive Name”, “Mode” and “Size (GB)” in the
following example might be different from your system.
Select Array Mode and press <Enter>, a list of array modes will appear.
Highlight the target array mode that you want to create, and press <Enter> to
confirm the selection. If RAID 1 or RAID 0/1 is selected, an option list will
popup and enable the users to select Create only or Create and duplicate.
Create only will allow BIOS to only create an array. The data on the mirroring
drive may be different from the source drive. Create and duplicate lets BIOS
copy the data from the source to the mirroring drive.

After array mode is selected, there are two methods to create a disk
array. One method is “Auto Setup” and the other one is “Select Disk Drives”.
Auto Setup allows BIOS to select the disk drives and create arrays automatically,
but it does not duplicate the mirroring drives even if the user selected Create
and duplicate for RAID 1. It is recommended all disk drives are new ones when
wanting to create an array. Select Disk Drives lets the user select the array
drives by their requirements. When using Select Disk Drives, the channel
column will be activated. Highlight the target drives that you want to use and
press <Enter> to select them. After all drives have been selected, press <Esc>
to go back to the creation steps menu.
If user selects a RAID 0 array in step 2, the block size of the array can also
be selected. Use the arrow key to highlight Block Size and press <Enter>,
then select a block size from the popup menu. The block size can be 4KB to
64KB.

Even though 64KB is the recommended setting for most users, you
should choose the block size value which is best suited to your
specific RAID usage model.
4KB: For specialized usage models requiring 4KB blocks
8KB: For specialized usage models requiring 8KB blocks
16KB: Best for sequential transfers
32KB: Good for sequential transfers
64KB: Optimal setting
Use the arrow key to highlight Start Create Process and press <Enter>.
A warning message will appear, Press Y to finish the creation, or press N to
cancel the creation.
Important note: All existing content in the hard drive will be destroyed
after array creation.

Delete Disk Array
A RAID can be deleted after it has been created. To delete a RAID, use
the following steps:
1. Select Delete Array in the main menu and press <Enter>. The channel
column will be activated.
2. Select the member of an array that is to be deleted and press <Enter>. A
warning message will show up, press Y to delete or press N to cancel.
Deleting a disk array will destroy all the data on the disk array except
RAID 1 arrays. When a RAID is deleted, the data on these two hard disk drives
will be reserved and become two normal disk drives.

Duplicate Critical RAID 1 Array
When booting up the system, BIOS will detect if the RAID 1 array has
any inconsistencies between user data and backup data. If BIOS detects any
inconsistencies, the status of the disk array will be marked as critical, and BIOS
will prompt the user to duplicate the RAID 1 in order to ensure the backup data
consistency with the user data.
If user selects Continue to boot, it will enable duplicating the array after
booting into OS.

Rebuild Broken RAID 1 Array
When booting up the system, BIOS will detect if any member disk drives
of RAID has failed or is absent. If BIOS detects any disk drive failures or
missing disk drives, the status of the array will be marked as broken.
If BIOS detects a broken RAID 1 array but there is a spare hard drive
available for rebuilding the broken array, the spare hard drive will automatically
become the mirroring drive. BIOS will show a main interface just like a duplicated
RAID 1. Selecting Continue to boot enables the user to duplicate the array after
booting into operating system.
If BIOS detects a broken RAID 1 array but there is no spare hard drive
available for rebuilding the array, BIOS will provide several operations to
solve such problem.
1. Power off and Check the Failed Drive:
This item turns off the computer and replaces the failed hard drive with a
good one. If your computer does not support APM, you must turn off your
computer manually. After replacing the hard drive, boot into BIOS and select
Choose replacement drive and rebuild to rebuild the broken array.
2. Destroy the Mirroring Relationship:
This item cancels the data mirroring relationship of the broken array. For
broken RAID 1 arrays, the data on the surviving disk will remain after the
destroy operation. However, Destroy the Mirroring Relationship is not
recommend because the data on the remaining disk will be lost when the hard
drive is used to create another RAID 1 array.

3. Choose Replacement Drive and Rebuild:
This item enables users to select an already-connected hard drive to
rebuild the broken array. After choosing a hard drive, the channel column will
be activated.
Highlight the target hard drive and press <Enter>, a warning message
will appear. Press Y to use that hard drive to rebuild, or press N to cancel.
Please note selecting option Y will destroy all the data on the selected hard
drive.
4. Continue to boot:
This item enables BIOS to skip the problem and continue booting into
OS.
