12. AGP 8X Expansion Slot
10. IEEE 1394 Connectors
This motherboard has two IEEE 1394 connectors onboard. The IEEE 1394 provides data
transfer rate up to 400Mb/s. Therefore the IEEE 1394 interface can connect with the
devices that need high data transferring performance, such as digital camera, scanner or
others IEEE 1394 devices. Please use the proper cable to connect with devices.
This model provides an
AGP
8x slot which is the latest AGP specification. The AGP 8x calls for
the bus to operate at the basic AGP 66-MHz clock frequency and the bandwidth is 2.1Gbytes/s.
It is a great improvement on the performance of 3D graphic. AGP supports only memory
read/write operation and single-master single-slave one-to-one only. AGP uses both rising and
falling edge of the 66MHz clock, for 2X AGP, the data transfer rate is 66MHz x 4bytes x 2 =
528MB/s and AGP 4x mode, 66MHz x 4bytes x 4 = 1056MB/s. Now the transfer rate is 66MHz
x 4bytes x 8 = 2112MB/s.
Dr. Voice
is a great feature which can identify the problems you may encounter in the
operating system. It can clearly “
tell you
” whether the problem is caused from components
or improper installation such as CPU, memory module, VGA, PCI add-on card, FDD, HDD or
keyboard. Dr. Voice provides four language versions:
English
,
German
,
Japanese
and
Chinese
. You can select your preferred language by
JP15
&
JP16
jumpers. However, if you
want to disable this function, you may also adjust both JP1 and JP2 and set them to pin 2-3
to disable the buzzer and speaker from making out voices.

Warning: It is strongly
recommended not to install
a 3.3V AGP card, which is
not supported by SIS648.
When you do so, the AGP
LED on the motherboard
will light up to warn you the
possible damage.

Attach the power LED, speaker, and reset switch connectors to
the corresponding pins. If you enable “Suspend Mode” item in
BIOS Setup, the ACPI & Power LED will keep flashing while the
system is in suspend mode.
Locate the power switch cable from your ATX housing. It is 2-pin
female connector from the housing front panel. Plug this
connector to the soft-power switch connector marked
SPWR
.
