DRAM Clock/Drive Control
DRAM Clock
This control enables the user to choose either automatic or one of memory clock
frequencies.
Settings: [By SPD, 100 MHz, 133 MHz, 166 MHz, 200 MHz, 266 MHz, 333 MHz]
DRAM Timing
The value in this field depends on the memory modules installed in your system.
Changing the value from the factory setting is not recommended unless you install
new memory that has a different performance rating than the original modules.
Settings: [Manual, Auto By SPD]
SDRAM CAS Latency Control
This item adjusts the speed it takes for the memory module to complete a
command. Generally, a lower setting will improve the performance of your
system. However, if your system becomes less stable, you should change it to a
higher setting. This field is only available when “DRAM Timing” is set to “Manual”.
Settings: [1.5/2, 2/3, 2.5/4, 3/5]

Bank Interleave
Set the interleave mode of the SDRAM interface. Interleaving allows banks of
SDRAM to alternate their refresh and access cycles. One bank will undergo its
refresh cycle while another is being accessed. This improves performance of the
SDRAM by masking the refresh time of each bank. This field is only available
when “DRAM Timing” is set to “Manual”.
Settings: [Disabled, 2 Bank, 4 Bank, 8 Bank]
Precharge to Active (Trp)
This field controls the length of time it takes to precharge a row in the memory
module before the row becomes active. Longer values are safer but may not offer
the best performance. This field is only available when “DRAM Timing” is set to
“Manual”.
Settings: [2T - 5T]
Active to Precharge (Tras)
This field controls the length of time it a row stays active before precharging.
Longer values are safer but may not offer the best performance. This field is only
available when “DRAM Timing” is set to “Manual”.
Settings: [5T – 20T]
Active to CMD (Trcd)
This field is only available when “DRAM Timing” is set to “Manual”.
Settings: [2T - 5T]

This option is for setting a password for entering BIOS Setup. When a password
has been set, a password prompt will be displayed whenever BIOS Setup is run.
This prevents an unauthorized person from changing any part of your system
configuration.
There are two types of passwords you can set. A supervisor password and a user
password. When a supervisor password is used, the BIOS Setup program can be
accessed and the BIOS settings can be changed. When a user password is used,
the BIOS Setup program can be accessed but the BIOS settings cannot be
changed.
To set the password, type the password (up to eight characters in length) and
press <Enter
Enter>.
Enter The password typed now will clear any previously set password
from CMOS memory. The new password will need to be reentered to be
confirmed. To cancel the process press <Esc

Driver Utilities
Getting Started
VIA VB8002 developer kits include a driver CD that contains the drivers and
software for enhancing the performance of the mainboard. The drivers can also
be downloaded from http://www.viaembedded.com
Note:
The driver utilities and software are updated from time to time. The latest
updated versions are available at http://www.viaembedded.com
Running the Driver Utilities CD
To start using the CD, insert the CD into the CD-ROM or DVD-ROM drive. The CD
should run automatically after closing the CD-ROM or DVD-ROM drive. The
driver utilities and software menu screen should then appear on the screen. If the
CD does not run automatically, click on the “Start” button and select “Run…” Then
type: "D:\Setup.exe".
For Linux drivers, click the right button on mouse and click open. Linux drivers
are located in the "Driver" folder.
Note:
D: might not be the drive letter of the CD-ROM/DVD-ROM in your system.
