M6VLB with VIA Apollo PLE133 northbridge which graphics core is taken from Trident Blade3D with 8Mb of system frame buffer sizes.However, the M6VSA Is using PM133 as northbridge which taken a graphics core from S3(a combination of the 3D-component from Savage4 and 2D from Savage2000) with 32Mb of system frame bffer size. The larger the system frame buffer size the better the Video perfromance.

The TWL0423F BIOS, which is published on the website is only for the latest version of M6TWL, Version 2.0. In TWL Version 2.0, the BIOS EEPROM sizes are reduced to 2MB. Therefore, "The File Size Does Not Match" message will pop-up, when reflash 2M BIOS into 4M EEPROM.

Basically, the M6VCG and M6VCT have same functionality and specifications .The major different is M6VCT can support Intel Tulatin CPU.Tualatin CPU utilized .13-micron process technology also come with 512KB of Level 2 cache. For further information regarding the Tualatin CPU please visit http://www.intel.com.

The system is designed to support Intel Tulatin CPU, so it is just to support Vcore voltage between 1.25V and 1.8V, only. The Intel Celeron (PPGA Type) CPU and Cyrix III CPU are used over this voltage range, so the motherboard is unable to support it.

The BIOSTAR Watchdog Technology was designed to protect PC from inappropriate over-clock situations. Any Over-Clock that reaches the threshold settings, the system will lock up. In this case to active the system again, you must opening the case and Clear the CMOS. However the Watchdog technology can be able to squandering your time to skip this procedure. The only things you need to do are unplugging and re-plug the Power cord. After that, press the key and power on the system simultaneously to restart the system. The Watch Dog technology will Load the Fail Save default. M7NCG Motherboard support this function.

The SPDIF (Sony/Philips Digital Interface) is the newest audio transfer file formatting which provides impressive quality through optical fiber and allows the users to enjoy digital audio instead of analog audio. Normally there are two S/PDIF outputs, one for RCA connector, the most common one used for consumer audio products, and the other one is for optical connector with a even better audio quality. Through a specific audio cable, users can connect the SPDIF connector to other end of the S/PDIF audio module, which bears S/PDIF digital out put.
Attached is the Pin assembly of SPDIF connector for your reference

Basically, the anti-Intrusion is the name as "Chassis Open". This function is able to detect whether the PC Case is open or not. For instance, if the PC case is Open, the Motherboard will cause the beep sound and the error Message will also show up on the screen to warn the customer that the PC case was not closed properly. For your information, you can active this function under the CMOS Setup Menu by following the instructions below

1. Press "Delete" Key to enter into the CMOS Setup Menu during the boot screen.
   
   
2. Select "PC Health Status"
   
   
3. Setup the "Chassis Open Warnning" to "Enabled"
   
   
   
4. Save and Quit the CMOS Setup Menu.
   

By the way, the PC case must support anti-Intrusion to use this function.

Biostar has to design a new technology to protect your AMD XP CPU. Our name as CPU Savior. The AMD latest XP CPU has been integrated a function to provide CPU working temperature. We had to put an IC to detect the current AMD XP CPU temperature, then report to system PWM IC and turn off your system. That mean if your AMD XP CPU current temperature was detected higher, then the CPU allow limit by your CPU FAN stop to run or that's a Gap between CPU and Heatsink, your system will shut down, automatically.

Note!K You must clear your system CMOS before to turn on your system, again. Also, the new CPU Savior technology just to depend on AMD XP CPU, only. In early stage, the AMD Athlon and Duron which are not support this function. Last, let us to summarize this work procedure as below.

1. AMD XP CPU Temperature is reached the limit.
2. System will shut down, automatically.
3. Clear CMOS.
4. Make sure the CPU ran is working properly, the contact area between CPU and the heatsink is evenly.
5. Turn On your computer.

Both of USB 2.0 and I1394 are increased system transfer speed for external devices. Now, let us to explain these Spec. for USB 2.0 and I1394 as below:

1. USB 2.0:
   A core team from Compaq, Hewlett Packard, Intel, Lucent, Microsoft, NEC and Philips is leading the development of the USB Spec. For Example: An external USB 2.0 hub has an input rate of 480Mb/s and output rates of 480Mb/s for attached high speed USB 2.0 peripherals. This backwards-compatible extension of the USB 1.1 Spec. Uses the same cables, connectors and software interfaces so the user will see no change in the usage model. In Biostar, most of motherboards able to support this function, such as P4TPT, P4TDQ P4TGV!K.
2. I1394:
   IEEE STD 1394-1995, Standard for a High Performance Serial Bus, defines facilities in the cable environment for the distribution of power to connected devices. For Example: An external I1394 hub able to provide 400Mb/s for attached high-speed I1394 peripherals. In Biostar product, you can find 10 Pins Red Header on motherboard.

Intel's Hyper-Threading (HT) Technology is an essential element of Intel's strategy to successfully ramp performance, control power consumption, and manage heat dissipation into the coming decades. In its current implementation, HT Technology delivers two logical processors that can execute different tasks simultaneously using shared hardware resources. Of course, the new technology must be used with BIOS and Microsoft New Operating System as Windows XP. The pervious O/S as 98SE, ME and 2000 those are unable to support this function. Also, Intel has release new 3.06GHz or above CPU which able supported this function. The mean that you are need to use the Intel 3.06GHz, supported BIOS and Microsoft Windows XP operating system.

Currently, we have launched these products as below to support the Intel New Technology.
