SiS650GL or SiS651 Northbridge and SiS961 (or SiS962) Southbridge chip-
sets that supports built-in AC97 Codec, 2DDR + 2 SDR modules up to 2GB
system memory, and provide Ultra DMA 33/66/100/(133)function. In addition,
the mainboard integrates a256-bit 3D/2D Graphics Engine, Video Accelera-
tor and Advanced Hardware Acceleration MPEGI/MPEGII Video Decoder for

There are many types of computer cases on the market. The mainboard com-
plies with the specifications for the micro-ATX system case. Some features on
the mainboard are implemented by cabling connectors on the mainboard to
indicators and switches on the system case. Ensure that your case supports
all the features required. The mainboard can support one floppy diskette drive
and four enhanced IDE drives. Ensure that your case has sufficient power and
space for all the drives that you intend to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that
the I/O template in the case matches the I/O ports installed on the rear edge
of the mainboard.
Thismainboardhasamicro-ATX form factor of 244 x 244 mm. Choose a case
thataccommodates this form factor.
This concludes Chapter 1. The next chapter explains how to install the main-
board.

Follow these safety precautions when installing the mainboard:
•Wear a grounding strap attached to a grounded device to avoid
damage from static electricity.
•Discharge static electricity by touching the metal case of a safely
grounded object before working on the mainboard.
•Leave components in the static-proof bags they came in.
•Hold all circuit boards by the edges. Do not bend circuit boards.
