CPU Thermal Protection
Aimed to prevent the CPU from overheating, MSI has developed a CPU
Thermal Protection mechanism for AMD Athlon™ XP CPU platform. This CPU
Thermal Protection mechanism works on a thermal signal sensor. If the
mechanism senses an abnormal temperature rise, it will automatically shut down
the system and the CPU temperature will then drop down and resume normal.
With this unique feature, users can better protect their CPU. Please note that
this feature is for AMD Athlon™ XP CPU only.
S-Bracket (Optional)
S-Bracket is a bracket which provides 2 SPDIF jacks for digital audio
transmission and 2 analog Line-Out connectors for additional 4-channel ana-
log audio output. With the S-Bracket, your system will be able to perform 6-
channel audio operation for wonderful surround sound effect, or connect to
Sony & Philips Digital Interface (SPDIF) speakers for audio transmission with
better quality.
The S-Bracket offers two types of SPDIF connectors: one for optical
fiber and the other for coaxial connection. Select the appropriate one to meet
your own need. For more information on S-Bracket, refer to Appendix. Using
4- or 6-Channel Audio Function.
