CPU
The VIA VB7007 mainboard is packaged with a standard VIA C7®-D 1.5 GHz
NanoBGA2 processor. The VIA C7®-D 1.5 GHz processor requires a heatsink with
fan to provide sufficient cooling.
CPU Fan and System Fan: CPUFAN and SYSFAN
The CPU_FAN (CPU fan) and SYS_FAN (system fan) run on +12V and maintain
system cooling. When connecting the wire to the connectors, always be aware
that the red wire (positive wire) should be connected to the +12V. The black wire
is Ground and should always be connected to GND.

Jumpers
The mainboard provides jumpers for setting some mainboard functions. This
section will explain how to change the settings of the mainboard functions using
the jumpers.
Clear CMOS Connector: CLEAR_CMOS
The onboard CMOS RAM stores system configuration data and has an onboard
battery power supply. To reset the CMOS settings, set the jumper on pins 1 and 2
while the system is off. Return the jumper to pins 2 and 3 afterwards. Setting the
jumper while the system is on will damage the mainboard.

CautionCaution
Except when clearing the RTC RAM, never remove the cap on CLEAR_CMOS
jumper default position. Removing the cap will cause system boot failure.
Avoid clearing the CMOS while the system is on; it will damage the
mainboard.

Peripheral Component Interconnect: PCI_SLOT
The PCI slot allows you to insert a PCI expansion card. First unplug the power
supply before adding or removing expansion cards. Read the documentation for
the expansion card to see if any changes to the system are necessary.
PCI Interrupt Request Routing
The IRQ (interrupt request line) are hardware lines over which devices can send
interrupt signals to the microprocessor. The “PCI & LAN” IRQ pins are typically
connected to the PCI bus –INT_A ~ -INT_D pins as follows:

Parallel Port Mode
Set the parallel port mode. To operate the onboard parallel port as Standard
Parallel Port, choose SPP. To operate the onboard parallel port in the EPP mode,
choose EPP. By choosing ECP, the onboard parallel port will operate in ECP mode.
Choosing ECP + EPP will allow the onboard parallel port to support both the ECP
and EPP modes simultaneously.
Settings: [SPP, EPP, ECP, ECP + EPP]
EPP Mode Select
EPP (Enhanced Parallel Port) comes in two modes: 1.9 and 1.7. EPP 1.9 is the
newer version of the protocol and is backwards compatible with most EPP
devices. If your EPP device does not work with the EPP 1.9 setting, try changing
the setting to EPP 1.7.
Settings: [EPP 1.9, EPP 1.7]
ECP Mode Use DMA
ECP (Extended Capabilities Port) has two DMA channels that it can use. The
default channel is 3. However, some expansion cards may use channel 3 as well.
To solve this conflict, change the ECP channel to 1. Select a DMA channel for the
port.

SDRAM CAS Latency
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

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

Driver Utilities
Getting Started
VIA VB7007 Developer kits include a driver CD that contains the drivers and
software for enhancing the performance of the mainboard. Regular kits do not
include a driver CD. However, the latest drivers can be downloaded from
http://www.via.com.tw.

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.
