Caution! When installing a CPU heatsink and cooling fan make sure that you DO NOT scratch the motherboard or any of the surface-mount resistors with the clip of the cooling fan. If the clip of the cooling fan scrapes across the mainboard, you may cause serious damage to both the mainboard and the processor. On most mainboards, there are small surface-mount resistors near the processor socket, which may be damaged if the cooling fan is carelessly installed. Avoid using cooling fans with sharp edges on the fan casing and the clips. Also, install the cooling fan in a well-lit work area so that you can clearly see the mainboard and processor socket.

The MS7127C mainboard is an ATX mainboard that uses a 4-layer printed circuit board and measures 304 mm x 190 mm. The mainboard features a Socket 370 that accommodates PPGA Celeron, FC-PGA Pentium III, and Cyrix III processors that support frontside bus (FSB) speeds up to 133 MHz. The MS7127C uses the VIA family chipset and features the AC 97 audio codec. The mainboard is equipped with a 2xAGP (Accelerated Graphics Port) slot and two PCI Bus Master Ultra DMA (UDMA) ports that support up to four ATAPI (AT Attachment Packet Interface) devices. The PCI IDE also supports PIO Mode 3 and 4, UDMA33/66 IDE (UDMA100 is optional), and an ATAPI CD-ROM. Note: The MS7127C supports two VIA South Bridge chipsets-- the VIA VT82C686A and the VIA VT82C686B. The VIA VT82C686A is standard and supports UDMA33/66. The VIA VT82C686B is optional and supports UDMA100. The mainboard accommodates PC 100 SDRAM (Synchronous DRAM) up to 1.5 GB using three 3.3V unbuffered DIMM modules. The MS7127C also has a full set of I/O ports, such as dual channel IDE interfaces, a floppy controller, two FIFO serial port connectors, an EPP/ECP-capable bi-directional parallel port connector, a dual USB (Universal Serial Bus) connector, and PS/2 keyboard and mouse connectors.

Software support CD-ROM disc Recommendations This mainboard automatically determines the CPU clock frequency and system bus frequency for the kind of processor that you install. You may be able to change these automatic settings by making changes to jumpers on the mainboard, or changing the settings in the system Setup Utility. We strongly recommend that you do not overclock the mainboard to run processors or other components faster than their rated speed. Warning: Overclocking components can adversely affect the reliability of the system and introduce errors into your system. Overclocking can permanently damage the mainboard by generating excess heat in components that are run beyond the rated limits. 2 Components on this mainboard can be damaged by discharges of static electricity. Handle the board carefully holding it by the edges. Do not flex or stress the circuit board. Keep the board in its static-proof packing until you are ready to install it. Follow the static guidelines given at the beginning of Chapter 2. Features The key features of this mainboard are the wide range of processors that can be installed, and the high level of integration. Value-class Processors Functioning as a platform for a value PC, the MS7127C features a Socket 370 that accommodates PPGA Celeron, Pentium III, and Cyrix III processors. The MS7127C supports 66/100/133 MHz FSB speeds. VIA North Bridge Chipset This board features the VIA VT82C693A NB (North Bridge) chipset, enabling synchronous and asynchronous frequency operation between the processor and the memory over a wide frequency range. The NB chipset is optimized for Pentium III processors at 66/100/133 MHz Front Side Bus (FSB) frequency and supports 32-bit processor bus addressing. The following host/DRAM clocking configurations are supported: · · · · · · · 66/66 66/100 100/66 100/100 100/133 133/100 133/133. The integrated DRAM controller supports up to three doublesided DIMMs or six banks up to 1.5 GB using 256 MB DRAM technology. The NB chipset provides SDRAM with a 64-bit data interface. 3 The AGP interface is AGP specification Rev 2.0 compliant, and supports 2x devices. The PCI bus interface complies with PCI Rev. 2.2, and supports 3.3V and power supplies. Five PCI bus masters are supported in addition to the host and PCI-to-ISA I/O bridge. VIA South Bridge Chipset Note: The MS7127C supports two VIA South Bridge chipsets-- the VIA VT82C686A and the VIA VT82C686B. The VIA VT82C686A is standard and supports UDMA33/66. The VIA VT82C686B is optional and supports UDMA100. The VIA VT82C686A SB (South Bridge) chipset comes in a 352-pin BGA package. The PCI to ISA Bridge has an integrated ISA bus controller with integrated DMA, timer, and interrupt controllers. The VIA VT82C686A chipset supports UDMA33/66. As an option you can get the MS7127C with the VIA VT82C686B SB chipset, which supports UDMA100. The Real Time Clock features extended 256 byte CMOS RAM and a day and month alarm for the ACPI (Advanced Configuration and Power Interface). There is an integrated USB controller with a built-in root hub and four function ports. The integrated Ultra DMA33/66 master mode EIDE controller with enhanced PCI bus commands. The UltraDMA33/66 Master Mode PCI EIDE controller features dual channel master mode PCI supporting Enhanced IDE (EIDE) devices and employ transfer rates up to 33 MB/sec to cover PIO mode 4, multi-word DMA mode 2 drives, and UltraDMA-33 interface. The SB chipset also supports ATAPI compliant devices including DVD devices and four USB 1.1 ports for serial transfers at 12 or 1.5 Mbits/sec. The integrated super IO controller supports two serial ports, an IR port, parallel port, and floppy disk controller functions. There is also system monitor support, providing system feedback of voltage, temperature, and fan speed conditions. 4 Inexpensive Memory The board has three DIMM sockets for the installation of 168-pin, 3.3V non-buffered DIMM memory modules. The DIMM memory modules can be SDRAM or VCM memory chips. AGP Graphics Adapter Slot The MS7127C includes a 2xAGP slot that provides twice the bandwidth of the original AGP specification. AGP technology provides a direct connection between the graphics sub-system and the processor so that the graphics do not have to compete for processor time with other devices on the PCI bus. The AGP design allows the graphics controller to use part of the main memory when it needs it, for example, in handling the very large texture maps required by virtual reality and 3D video games and applications. AC 97 Audio Codec The AC 97 Audio codec is compliant with the AC 97 2.1 specification, and supports 18-bit ADC (Analog Digital Converter) and DAC (Digital Analog Con ...
