SB-Link is a connector(J1) on the mainboard which is especially for use with
a Creative Labs PCI soundcard. The SB-link guides signals from the ISA bus
to the PCI soundcard through a cable which comes with the PCI soundcard .
This is necessary because some DOS based games address the ISA bus
d i re c t l y. In this way compatibility with these games is guaranteed.

N O T E : SB-Link
The official explanation of SB-Link (as posted on Creative Labs website) is
as follows:

SB-LINK combines Intel's PC-PCI and "Serialized IRQ" protocols. These
technologies can be found in Intel's TX, LX and newer core logic chip sets.
This technology provides the DMA and IRQ signals present in ISA Bus
t o d a y, but not available on the PCI Bus. The SB-LINK serves as a bridge
between the motherboard and PCI sound card to deliver Sound Blaster 16
compatibility for real-mode DOS games, a widely accepted audio standard
in Multimedia Personal Computers.
SB-LINK, endorsed by leading motherboard suppliers, is becoming a
s t a n d a rd audio connector on new motherboards. With SB-LINK, sound
c a rd users can look forward to the best gaming experience ever.

2-11. Integrated VGA (SiS620)

2-11-1 Overview

The CB649M-SI provides built-in 3D AGP VGA controller (SiS620).
The integrated graphics accelerator is compatible with AGP1.0 and
PCI2.2 configuration.
The CB649M-SI provides two options -- UMA and Non-UMA modes
for display memory allocation.
In UMA mode, the display memory is shared with system memory and
user can select 2/4/8MB of system memory as dispaly memory on the
system SETUP.
In Non-UMA mode, on-board SGRAM (up to 4MB) is used as display
memory and the display memory size is fixed from factory 2 or 4MB
S G R A M .
The SiS620 super-AGP arc h i t e c t u re provides 800MB/s bandwidth
between VGA and host bus, which is 50% more than the AGP 2X
mode(532MB/s). The display memory interface bus frequency can also
be operated at up to 100MHz, with 64-bit data path.
In summary, CB649M-SI provides consistent 800MB/s bandwidth
among internal module as well as external memory interfaces, and

delivers high performance in 2D and 3D applications.

NOTE :

In UMA mode, System will use First Bank of system memory as dispaly
memory so that user install the system memory into the DM1 slot.

NOTE :

CB649M-SI motherboard provides built-in AGP video contro l l e r.
If you need to change video card for your special purpose, use JP3 to
disable the internal VGA.

3 BIOS Setup

This chapter provides information on how the setup program allows you to
c o n f i g u re the functions and devices of your computer and how to configure
each item on the setup menus.

B e f o re the computer can operate, it must be known what devices are
installed in it. These devices include floppy and fixed-disk drives, video,
and so forth. Taken together, the presence or absence of these devices
comprise the system configuration. Use the SETUP program to verify or
change the system configuration.

CB649M-SI User’s Manual

O rd i n a r i l y, there should be no need to run SETUP the first time you start up
your system, since your computer comes from the factory ready to use. Yo u
must, however, run the SETUP program each time you make any changes
to your computer’s configuration, such as adding drives, and so forth. Yo u
can also run it to verify the system configuration.

3-1 Starting Setup

The SETUP program is permanently stored in a “Flash EEPROM” and not
contained on disk. The SETUP program can be accessed:

• When powering up the system & When resetting the system

• When the system detects an error and prompts for the setup pro g r a m

1. Accessing SETUP When Powering Up the System

To access the SETUP program when powering up the system, turn the
computer power on. The system BIOS will first test the system components
and then display a message similar to the following:

IDE HDD AUTO DETECTION

” o p t i o n

LBA : This stands for Logical Block Addressing, the current standard access

mode for large IDE hard disk drive. It allows the use of hard disks
l a rger than 528MB by causing the IDE controller to translate between
the logical address, it create and the hard disk’s actual physical
a d d ress. The maximum drive size supported is 8.4GB.

L a rge : For 1GB or smaller drives with more than 1024 cylinders and no

LBA support. This access mode causes the Operating System to
t reat the drive as if it has fewer than 1024 cylinders by dividing the
cylinders in half and doubling the number of heads. Drives needing
this mode are less common.

Most large IDE hard disk drives currently available use the LBA
m o d e .

Use the Auto setting to automatically detect the correct mode for
new drives.

CB649M-SI User’s Manual

The first chipset settings deal with CPU access to dynamic random access
memory (DRAM). The default timings have been carefully chosen and
should only be altered if data is being lost. Such a scenario might well occur
if your system have mixed speed DRAM chips so that greater delays may
be re q u i red to preserve the integrity of the data held in the slower memory
c h i p s .

It also coordinates communications between the conventional ISA bus and
the PCI bus. It must be stated that these items should never need to be
a l t e red. The default settings have been chosen because they provide the best
operating conditions for your system. The only time you might consider
making any changes would be if you discovered that data was being lost
while using your system.
