We strongly recommend that you do not overclock the mainboard to run processors or other components faster than their rated speed. 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. Components on this mainboard can be damaged by discharges of static electricity. Handle the board carefully holding it by the edges. Don't flex 3 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 support for both AT and ATX power supplies. Wide Choice of Processors This mainboard provides an excellent platform for an inexpensive value PC that is internet-ready thanks to the fax/modem module. The socket370 can be installed with a PPGA Celeron processor. The PPGA Celeron has 32k of internal cache memory, 128K of external cache memory, and operates over a 66 MHz system bus. The PPGA Celeron ships with clock speeds running from 300 MHz through to 500 MHz. The PPGA Celeron is the ideal processor choice for an entry-level PC. For better performance, the MS7101C can be installed with a slot1 processor. The SEPP (Single Edge Processor Package) Celeron is the least expensive slot-1 processor. It has 32K of internal cache memory, 128K of external cache memory (except for older versions), and operates over a 66 MHz system bus. SEPP Celerons ship with clock speeds ranging from 266 MHz through to 500 MHz. For higher-performance business-class computing, the slot1 can be installed with a Pentium-II or Pentium-III processor cartridge. The Pentium-II and Pentium-III have 32K of internal cache memory and 512K of external cache memory. They operate over a 100 MHz system bus (except for older versions). The Pentium-III includes new instructions that are designed to enhance multimedia/internet computing by providing rapid encoding and decoding of the compressed audio and video files which are pervasive in the internet environment. The Pentium-II ships with clock speeds running from 233 MHz through to 450 MHz. The Pentium-III ships with clock speeds of 450 MHz, 500 MHz and 550 MHz. VIA Apollo Pro Plus Chipset The VIA Apollo Pro Plus chipset is a high performance chipset that ensures full support for Intel's Slot1 and socket-370 processors. The chipset supports both 66 MHz and 100 MHz front side buses and SDRAM memory installation of up to 768 MB. Support is provided for a 2x AGP slot and Rev. 2.2 PCI slots with Ultra DMA 33/66. The chipset is compliant with the PC98/99 specifications. 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 must be installed with SDRAM memory chips. The board supports a memory bus of 66 MHz or 100 MHz, so you can choose between inexpensive 66 MHz memory modules or high-performance PC-100 memory modules. Each installed memory module can be populated with 8 MB up to 256 MB of memory, so a maximum total of 768 MB memory can be installed. Highly Integrated Design The ITE LPC I/O controller handles the mainboard's I/O functions. The CMI 8738/PCI C3DX is a two-chip solution that provides an integrated audio and fax/modem system. Built-in PCI 3D Sound The system includes built-in PCI 3D audio support. The chip provides Sound Blaster 16-bit-compatible audio, plus support for Microsoft's DirectSound 3D specification and Aureal A3D interface. The sound ports include jacks for speakers, microphone and stereo in, and a game/MIDI port. The audio system supports full duplex operation and drivers are available for WIN 95/98 and WIN NT 4.0. The audio system can output sound to 4 loudspeakers and also supports SPDIF 24-bit digital sound input and output. Built-in V.90 Fax/modem The mainboard includes an integrated fax/modem. The fax/modem supports 56 Kbps transmission using the V.90 protocol. The fax/modem is integrated with the built-in audio system to support voice as well as data transmissions. You must install a fax/modem module (with line and telephone sockets) in order to use the integrated fax/modem. Expansion Options The board has plenty of expansion potential with one 2x AGP slot for an AGP graphics adapter, three 32-bit PCI slots, and one legacy 8/16-bit ISA slot. The ISA slot is shared with one of the PCI slots which means that you can use either of the slots but not both at the same time. The PCI slots support Ultra DMA with speeds of 33/66 MHz. Integrated I/O Using the ITE LPC I/O chip and the VIA Apollo Pro Plus chipset, the board has a comprehensive set of integrated I/O ports. The I/O ports are installed as connectors on the mainboard and can be installed on the system case using extension brackets. The I/O ports include one PS/2 mouse port, a parallel port, two USB ports, and an infrared port. The 5 mainboard includes connections for floppy diskette drives and two PCI IDE channels. Keyboard Power On Feature Using the system BIOS setup program, you can configure the system to turn on using a keyboard typed password. A green keyboard is not required. Hardware Monitoring The system supports hardware monitoring so that monitoring software applications can generate warnings if critical parameters, such as voltages and temperatures, are exceeded Programmable Firmware The mainboard includes Award BIOS which allows BIOS setting of CPU parameters. The fully programmable firmware enhances the system features and allows users to set power management, CPU and memory timing, LAN and modem wake-up alarms, and so on. The firmware can also be used to set parameters for different Celeron processor clock speeds so that you don't need to change mainboard jumpers and switches. 6 Chapter 2: Installation Quick Installation Table This chapter explains how to successfully install the mainboard into a computer case and build a working system.

Ensure too that you are installing the mainboard into a suitable case. Static Electricity In adverse conditions, static electricity can accumulate and discharge through the integrated circuits and silicon chips on this product. These circuits and chips are sensitive and can be permanently damaged by static discharge. If possible wear a grounding wrist strap clipped to a safely grounded device during the installation. If you don't have a wrist strap, discharge any static by touching the metal case of a safely grounded device before beginning the installation. Leave all components inside their static-proof bags until they are required for the installation procedure. Handle all circuit boards and electronic components carefully. Hold boards by the edges only. Do not flex or stress circuit boards. 9 Choosing a Case This is a baby-AT sized mainboard that measures 220mm x 220mm. It has 3 PCI slots, one ISA slot and an AGP slot. The mainboard has connectors for either an ATX or an AT power supply so it can be installed in almost all computer cases. 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 MS7101C mainboard can support one or two floppy diskette drives and four enhanced IDE drives. Ensure that your case has sufficient power and space for all the drives that you intend to install. How to Set Jumpers A jumper consists of two or more pins mounted on the mainboard. Some jumpers might be arranged in a series with each pair of pins numbered differently. Jumpers are used to change the electronic circuits on the mainboard. When a jumper cap is placed on two jumper pins, the pins are SHORT. If the jumper cap is removed (or placed on just a single pin) the pins are OPEN. OPEN This illustration shows a 2-pin jumper. When the jumper cap is placed on both pins, the jumper is SHORT. If you remove the jumper cap, or place the jumper cap on just one pin, the jumper is OPEN. SHORT This illustration shows a 3-pin jumper. The jumper cap is placed on pins 2 and 3, so this jumper setting is SHORT PINS 2-3. This illustration shows the same 3-pin jumper. The jumper cap is placed on pins 1 and 2, so this jumper setting is SHORT PINS 1-2. In this manual, all the jumper illustrations clearly show the pin numbers. When you are setting the jumpers, make sure that the jumper caps are placed on the correct pins to select the function or feature that you want to enable or disable. 10 Preparing the Mainboard Mainboard Guide Use the following illustration and key to identify the components on your mainboard.

Install the Processor This mainboard has a Slot1 processor slot and a Socket-370 processor socket. You can only install one processor however, so you must choose what kind of processor to run on this board. To choose a processor, you need to consider the performance requirements of the system and also the price of the processor. Performance is based on the processor design, the clock speed and system bus frequency of the processor, and the quantity of internal cache memory and external cache memory. Higher clock speeds and larger amounts of cache memory deliver greater performance. About Slot1 Processors You can install three kinds of processor into the Slot1: Pentium-III, Pentium-II, and SEPP Celeron. Intel Pentium-III The Pentium-III has the highest performance. This processor is similar to the Pentium-II but it includes new instructions to improve the throughput of multimedia data such as 3D audio and video, speech recognition. MPEG2 motion picture encoding/decoding and TCP/IP internet connections. However, only recently released software has the capability of using these improved instructions. The Pentium-III has 32K of internal cache memory and 512K of external cache memory. Currently PentiumIII processors are available at clock speeds up to 550 MHz and they operate over a 100 MHz system bus. The Pentium-III is the most expensive of the processors supported by this mainboard. Intel Pentium-II The Pentium­II has a wide range of performance. Pentium-II processors have shipped with clock speeds of 233 MHz through to 450 MHz. Currently you might find that stores only stock Pentium-IIs with clock speeds of 350 MHz and higher. Pentium-IIs with a clock speed of 350 MHz or higher operate over a 100 MHz system bus. Pentium-IIs slower than 350 MHz operate over a 66 MHz system bus. All Pentium-IIs have 32K of internal cache memory and 512K of external cache memory. Pentium-IIs are less expensive than Pentium-IIIs with the same clock speed. 18 Intel SEPP Celeron SEPP stands for Single Edge Processor Package. The SEPP Celeron is similar to a Pentium-II except that it only has 128K of external cache memory. The first generation of SEPP Celerons had no external cache memory at all and ran at 266 MHz. These Celerons do not ship currently but are still supported by this mainboard. SEPP Celerons are available with clock speeds of 266 MHz through to 500 MHz. They all operate over a 66 MHz system bus. The SEPP Celeron is less expensive than a Pentium-II with the same clock speed. About Socket-370 Processors The socket-370 only supports the Intel PPGA Celeron processor. Intel PPGA Celeron PPGA stands for Plastic Pin Grid Array. This is a description of the square plastic package that the processor is embedded in. The PPGA Celeron is identical to the SEPP Celeron, except for the external packaging. PPGA Celerons run at clock speeds from 300 MHz through to 500 MHz. All the current PPGA Celerons operate over a 66 MHz system bus. The PPGA Celeron is less expensive than a SEPP Celeron with the same clock speed. 19 Installing a Slot1 Processor This board has a SLOT1 processor cartridge slot. The slot must be installed with a cartridge holder that supports the processor cartridge. The cartridge holder may be already installed on your mainboard with the support brackets folded over. In this case simply pull the support brackets into the upright position. Cartridge holder Slot1 If the cartridge holder is not already installed, install it onto the slot1. Some cartridge holders are in two parts, one part for each end of the slot1. Other cartridge holders are a single assembly that sits over the whole length of the slot1. Some cartridge holders are secured in place with screws. If you have this kind of cartridge holder, don't overtighten the screws as this can stress the mainboard. Some cartridge holders are secured in place with plastic pins. In this case, place the mainboard on a foam plastic mat when you push the pins into place. Some cartridge holders also include a support bar for the processor heat sink. This bar installs to the side of the cartridge holder. Some processor cartridges have support struts for the heat sink which lock into the support bar. The documentation supplied with the processor shows how to do this. 20 Install the Processor Cartridge After you have installed the cartridge holder, follow the instructions supplied with the processor cartridge to insert the cartridge into the holder. If the processor has a cooling fan, connect the power cable of the fan to the power supply connector on the mainboard FAN1. Cooling fan power cable Processor Cartridge FAN1 cooling fan power connector The mainboard must be configured to deliver the correct clock speed and the correct system bus for the kind of processor that you have installed. You can do this by using the system setup utility. The first time you start the system, immediately enter the setup system and make the appropriate settings. Usually, you can automatically configure the CPU by using the BIOS Features page of the setup utility. See Chapter 3 for more information. Note: If you have installed a Slot1 processor cartridge, make sure that the Select Slot1 or Socket-370 jumper JP4 is at the appropriate setting. For a Slot1 processor, pins 1-2 are SHORT. 21 Installing a Socket-370 Processor If you have decided to install the mainboard with a PPGA Celeron processor, follow the steps below. Locate the Socket-370 and CPUFAN1 Locking lever Pin-1 corner Socket-370 FAN1 1. On the mainboard, locate the socket-370 and FAN1. 2. On the socket-370, pull the locking lever away from the socket to unhook it and then raise the locking lever to the upright position. 3. Identify the pin-1 corner on the socket-370 and the pin-1 corner on the processor. The socket pin-1 corner is adjacent to the handle of the locking lever. The processor pin-1 corner is beveled. 4. Matching the pin-1 corners, drop the processor into the socket. No force is required and the processor should seat into the socket easily. 5. Swing the locking lever down and hook it under the latch on the edge of the socket. This locks the processor in place. 6. Locate the power cable on the heatsink/cooling fan assembly that is attached to the top of the processor. 7. Plug the power cable into the CPUFAN1 12V power supply on the mainboard. 22 Socket-370 processor with heatsink/cooling fan assembly Cooling fan power cable Socket-370 with locking lever in upright position FAN1 cooling fan power supply The mainboard must be configured to deliver the correct clock speed and the correct system bus for the kind of processor that you have installed. You can do this by using the system setup utility. The first time you start the system, immediately enter the setup utility and make the appropriate settings. Usually, you can automatically configure the CPU by using the CPU & BIOS Features page of the setup utility. See Chapter 3 for more information. Note: If you have installed a socket-370 processor, make sure that the Select Slot1 or Socket-370 jumper JP4 is at the appropriate setting. For a socket-370 processor, pins 2-3 are SHORT. 23 Install the Memory Modules For this mainboard, you must use 168-pin 3.3V non-buffered Dual In-line Memory Modules (DIMMs). The memory chips must be standard or registered SDRAM (Synchronous Dynamic Random Access Memory). The memory bus can run at 66 MHz or 100 MHz. If your processor operates over a 100 MHz system bus, you must install PC-100 memory that also operates over a 100 MHz bus. If you install a processor that operates over a 66 MHz bus, you can install memory chips that operate at 66 MHz. You must install at least one memory module. You can install the memory module in either DIMM1, DIMM2 or DIMM3. Each module may be installed with up to 256 MB of memory so the maximum capacity is 768 MB. The mainboard supports memory chips that have EC (Error Correction) or ECC (Error Correction Code). 1. Locate the DIMM slots on the mainboard. DIMM2 Memory module Locking latches DIMM1 DIMM3 2.

Install a Hard Disk Drive and CD-ROM/DVD This section describes how to install IDE devices such as a hard disk drive and a CD-ROM/DVD drive. Note: Ribbon cable connectors are usually keyed so that they can only be installed correctly on the device connector. If the connector is not keyed make sure that you match the pin-1 side of the cable connector with the pin-1 side of the device connector. Each connector has the pin-1 side clearly marked. The pin-1 side of each ribbon cable is always marked with a red stripe on the cable. About IDE Devices. Your mainboard has a primary IDE channel interface (IDE1) and a secondary IDE interface (IDE2). The mainboard ships with one IDE ribbon cable which supports one or two IDE devices. All IDE devices have jumpers or switches that can be used to set the IDE device as MASTER or SLAVE. If you install two IDE devices on one cable, you must make sure that one device is set to MASTER and the other device is set to SLAVE. The documentation of your IDE device explains how to do this. If you want to install more than two IDE devices, obtain a second IDE cable and you can add two more devices to the secondary IDE channel. If there are two devices on the cable, make one MASTER and one SLAVE. Installing a Hard Disk Drive 1. Install the hard disk drive into the drive cage in your system case. 2. Plug the IDE cable into the primary IDE channel on the mainboard IDE1. 3. Plug one of the connectors on the IDE cable into the IDE connector on the back edge of the hard disk drive.

The setup utility stores data about the mainboard components and the configuration of devices that are connected to it. This information is used to test and initialize components at start-up time and to make sure everything runs properly when the system is operating. The setup utility is installed with a set of default values. You will probably have to make changes to the setup utility whenever you add new components to your system such as new disk drives. You may be able to generate increased performance by changing some of the timing values in the setup, but this can be limited by the kind of hardware you are using, for example the rating of your memory chips. In certain circumstances, the system may generate an error message that asks you to make changes to the setup utility. This happens when the system finds an error during the POST (Power On Self Test) that it carries out at start up. Starting the Setup Utility You can only start the setup utility shortly after the computer has been turned on. A prompt appears on the computer display which says "Press DEL to run Setup". When you see this prompt, press the Delete key, and the system will start the setup utility and display the main menu of the utility. Using the Setup Utility When you start setup, the main menu appears. The main menu of the setup utility shows a list of the options that are available. A highlight shows which option is currently selected. You can use the cursor arrow keys to move the highlight to other options. When an option is highlighted, you can execute the option by pressing the Enter key. Some options lead to dialog boxes which ask you verify that that you wish to execute that option. You usually answer these dialogs by typing Y for yes and N for no. Some options lead to dialog boxes which ask for more information. Setting passwords have this kind of dialog box. 38 Some options lead to tables of items that usually have a value on the right side. The value of the first item is highlighted, and you can use the cursor arrow keys to select any of the other values in the table of items. When an item is highlighted, you can change the value by pressing the PageUp or PageDown keys, or the Plus or Minus keys. The PageUp and Plus keys cycle forward through the available values, the PageDown and Minus keys cycle backwards through the values. When you are in the main menu, you can exit the utility by pressing the Escape key. You can save the current selections and exit the utility by pressing the F10 key. You can change the color scheme of the utility by pressing the F2 key while holding down the Shift key. When you are in one of the options that displays a dialog box, you can return to the main menu by pressing the Escape key. When you are in an option that displays a table of items, you can return to the main menu by pressing the Escape key. For some items, you can display a help message by pressing the F1 key. You can change the color scheme of the utility by pressing the F2 key while holding down the Shift key. Press F5 to discard any changes you have made and return all items to the value that they held when the setup utility was started. Press F6 to load the displayed items with a standard list of default values. Press F7 to load the displayed items with a high-performance list of default values. 39 How to Flash a New BIOS You can install an updated BIOS for this motherboard that you can download from the manufacturer's website. A new BIOS may provide support for new peripherals, improvements in performance or fixes to address known bugs. Install a new BIOS as follows: 1. Some mainboards have a Flash BIOS jumper that protects the current BIOS from being changed or overwritten. If your mainboard has this jumper, change the setting to allow flashing a new BIOS. 2. Your computer must be running in a real-mode DOS environment, not the DOS window of Windows NT or Windows 95/98. We recommend that you create a new formatted DOS system floppy diskette. 3. Locate the flash memory utility on the support CD-ROM. It's called AWD66.EXE. Copy this file to the new system diskette. 4. Copy the new BIOS file that you downloaded from the manufacturer's website to the newly formatted system diskette. 5. Turn off your computer and insert the newly formatted DOS diskette in your computer's diskette drive. 6. You might need to run the setup utility and change the boot priority items on the BIOS Features Setup page, to force your computer to boot from the floppy diskette drive first. 7. At the A:\ prompt, after your computer has booted a clean DOS from the diskette, type in the filename AWD66 and press Enter. 8. In the opening dialog box, type in the filename of the new BIOS and follow the onscreen directions to flash the new BIOS. 9. When the installation is complete, remove the floppy diskette from the diskette drive and restart your computer. If your mainboard has a Flash BIOS jumper, don't forget to reset the jumper to protect the newly installed BIOS from being overwritten. 40 Standard CMOS Setup Option This option displays a table of items which defines basic information about your system. Date and Time The Date and Time items show the current date and time held by your computer. If you are running a Windows OS, these items are automatically updated whenever you make changes to the Windows Date and Time Properties utility. Hard Disks Defaults: 0 These items show the characteristics of hard disk drives on the two available IDE channels. (Note that SCSI hard disk drives do not appear here.) You can automatically install most hard disks using the IDE HDD Auto Detect Option from the main menu. If you find that a drive cannot be automatically detected, you can use these items to select USER, then manually enter the characteristics of the drive. The documentation provided with your drive provides the data you need to fill in the values for CYLS (cylinders), HEAD (read/write heads), and so on. The drive documentation drive may not tell you what value to use under the MODE heading. If the drive is smaller than 528 MB, set MODE to Normal. If the drive is larger than 528 MB and it supports Logical Block Addressing, set MODE to LBA. Very few high-capacity drives do not support Logical Block Addressing. If you have such a drive, you might be able to configure it by setting the MODE to Large. If you're not sure which MODE setting is required by your drive, set MODE to Auto and let the setup utility try to determine the mode automatically. 41 Drive A and Drive B Default: 1.44M, 3.5 in., None These items define the characteristics of any diskette drive attached to the system. You can connect one or two diskette drives. Floppy 3 Mode Support Default: Disabled Floppy 3 mode refers to a 3.5" diskette with a capacity of 1.2 MB. Floppy 3 mode is sometimes used in Japan.
