Board Dimensions 1.4 Microprocessor The motherboard operates with 3.3 volt Pentium processors and 2.8 volt MMX technology Pentium processors. An onboard circuit detects the presence of a 3.3 volt or 2.8 volt processor. A linear voltage regulator circuit provides the required voltage from the 5.0 volt tap of the power supply. An on-board jumper enables use of VRE specified processors. Pentium processors that run internally at 75, 90, 100, 120, 133, 150, 166, 180, and 200 MHz are supported. The Pentium processor maintains full backward compatibility with the 8086, 80286, i386TM and Intel486TM processors. It supports both read and write burst mode bus cycles, and includes separate 8 KB on-chip code and data caches that employ a write-back policy. The Pentium processor includes an advanced numeric coprocessor that increases the speed of floating point operations, while maintaining backward compatibility with Intel486 DX math coprocessor and complying to ANSI/IEEE standard 754-1985. 1.4.1 Microprocessor Upgrade The board contains a 321-pin Socket 7 ZIF processor socket. Socket 7 supports a processor upgrade path that includes higher performance Pentium OverDrive processors than can be supported with socket 5. 9 TC430HX TC430HX ATX Motherboard Technical Product Specification 1.5 Memory 1.5.1 Main Memory The motherboard provides four 72-pin SIMM sockets that make it possible to install up to 128 MB of RAM. The sockets support 1M x 32 (4 MB), 2M x 32 (8 MB), 4M x 32 (16 MB), and 8M x 32 (32 MB) single- or double-sided modules. Minimum memory size is 8 MB and maximum memory size, using four 8M x 32 SIMM modules, is 128 MB. Memory timing requires 70 ns fast page devices or, for optimum performance, 60 ns EDO DRAM. If the maximum external microprocessor clock speed is 60 MHz or slower, 70 ns EDO DRAM may be used. Parity, ECC, and non-parity memory are all supported. The four sockets are arranged in two banks of two sockets each. The sockets are designated Bank 0 and Bank 1. Each bank provides a 64/72-bit wide data path. Both SIMMs in a bank must be of the same memory size and type, although the different types of memory may differ between banks. It is even possible to have 70 ns Fast Page DRAM in one bank and 60 ns EDO DRAM in the other, in which case each bank is independently optimized for maximum performance. Bank 0 only, Bank 1 only, or both of the banks may be populated. There are no jumper settings required for the memory size or type, that is automatically detected by the BIOS. Use only tin lead SIMMs when adding DRAM. 1.5.1.1 EDO DRAM Extended Data Out (or Hyper Page) DRAM holds the memory data valid until the next CAS# falling edge, unlike standard fast page mode DRAM which tri-states the memory data when CAS# negates to precharge for the next cycle. With EDO, the CAS# precharge overlaps the data valid time, allowing CAS# to negate earlier while still satisfying the memory data valid window time. 1.5.1.2 Parity/ECC DRAM Memory error checking and correction is supported via parity or ECC SIMMs. Parity or ECC SIMMs are automatically detected. However, the user must enter Setup to configure the SIMMs for either Parity or ECC operation. Parity memory will detect single bit errors. ECC memory will detect double bit errors and correct single bit errors. Errors may be generated by a defective memory module, different speeds of memory modules, or DMA or memory conflicts. 1.5.2 Second Level Cache The Xcelerated Controller device supports a second level cache that uses the high performance synchronous pipeline burst static RAM (PBSRAM). One factory option on some motherboards is an integrated 256 KB direct mapped write-back second level cache implemented with two 32K x 32 Pipeline Burst SRAM devices that take advantage of the Global Write Enable pin. An 8KB x 8 external Tag SRAM provides caching support for up to 64 MB of main memory. A second factory option is for the motherboard to be built with the Type 1 CELP connector, specified by Intel's COAST Module Specification version 3.0. The Type 1 CELP connector has a keying "hip" located at one end of the connector. This connector allows the use of both a GWE PBSRAM COAST module, and a GWE Asynchronous COAST module. The GWE PBSRAM 10 Board Description module will work in 82430FX 82430FX and 82430HX 82430HX designs from Intel. The GWE Asynchronous modules built for Intel's 82430VX 82430VX designs are not interchangeable with Asynchronous modules built for 82430FX 82430FX designs and will not work. The reason for this is the additional logic added to the 82430VX 82430VX modules to account for the GWE functionality built into the chipset. 1.6 Chipset The Intel 82430HX 82430HX PCIset consists of the 82439HX 82439HX Xcelerated Controller (TXC) and one 82371SB 82371SB PCI/ISA IDE Xcelerator (PIIX3) bridge chip. 1.6.1 82439HX 82439HX Xcelerated Controller (TXC) The 82439HX 82439HX provides all control signals necessary to drive a second level cache and the DRAM array, including multiplexed address signals. The TXC also controls access to memory and generates snoop controls to maintain cache coherency. The TXC comes in a 324-pin BGA package and includes the following features: · · · · 1.6.2 Microprocessor interface control Integrated L2 write-back cache controller Pipeline burst SRAM 256 KB direct-mapped Integrated DRAM controller 64 bit path to memory Support for EDO and fast page DRAM Parity and non-parity support Fully synchronous PCI bus interface 25/30/33 MHz bus speed PCI to DRAM > 100 Mbytes/sec Up to four PCI masters in addition to the PIIX3 and IDE. PCI/ISA IDE Xcelerator (PIIX3) The PIIX3 provides the interface between the PCI and ISA buses and integrates a dual channel fast IDE interface capable of supporting up to four devices. The PIIX3 integrates seven DMA channels, one 16-bit timer/counter, two eight-channel interrupt controllers, PCI-to-AT interrupt mapping circuitry, NMI logic, ISA refresh address generation, and PCI/ISA bus arbitration circuitry together onto the same device. The PIIX3 comes in a 208-pin QFP package and includes the following features. · · · · Interface between the PCI and ISA buses Universal Serial Bus controller Host/hub controller Integrated fast IDE interface Support for up to four devices PIO Mode 4 transfers up to 16 MB/sec Integrated 8 x 32-bit buffer for bus master PCI IDE burst transfers Bus master mode PCI 2.1 compliant 11 TC430HX TC430HX ATX Motherboard Technical Product Specification · · · · 1.6.3 Enhanced fast DMA controller Interrupt controller and steering Counters/timers SMI interrupt logic and timer with fast on/off mode Universal Serial Bus (USB) Support The motherboard provides two USB ports. This permits the connection of two USB peripheral devices directly to the system without an external hub. If more devices are required, an external hub can be connected to either of the built-in ports. The motherboard completely supports the standard universal host controller interface (UHCI) and takes advantage of the standard software drivers written to be compatible with UHCI. Features of the USB include: · · · · · · 1.6.4 Self-identifying, "hot plugged" peripherals Automatic mapping of function to driver and configuration Support for isochronous and asynchronous transfer types over the same set of wires Support for up to 127 physical devices Guaranteed bandwidth and low latencies appropriate for telephony, audio, and other applications Error handling and fault recovery mechanisms built into protocol IDE Support The motherboard provides two independent high performance bus-mastering PCI IDE interfaces capable of supporting PIO Mode 3 and Mode 4 devices. The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Sector Head (ECHS) translation modes as well as ATAPI (e.g. CD-ROM) devices on both IDE interfaces. Detection of IDE device transfer rate and translation mode capability is automatically determined by the BIOS. Normally, programmed I/O operations require a substantial amount of microprocessor bandwidth. In true multi-tasking operating systems like Windows 95, the microprocessor bandwidth freed up by using bus mastering IDE can be used to complete other tasks while disk transfers are occurring. When used in conjunction with the appropriate driver for the Windows 95 environment, the IDE interface can operate as a PCI bus master capable of supporting PIO Mode 4 devices with transfer rates of up to 16 MB/sec. 1.7 I/O Controller Control for the integrated serial ports, parallel port, floppy drive, RTC and keyboard controller is incorporated into a single component, the National Semiconductor PC87306B PC87306B. This component provides: · · · · 12 Two NS16C550-compatible UARTs with send/receive 16 byte FIFO Support for an IrDA compliant Infra Red interface Multi-mode bi-directional parallel port Standard mode; IBM and Centronics compatible Enhanced Parallel Port (EPP) with BIOS/Driver support High Speed mode; Extended Capabilities Port (ECP) compatible Industry standard floppy controller with 16 byte data FIFO (2.88 MB floppy support) Board Description · · Integrated real-time clock accurate within +/- 13 minutes/year at 25° C and 5V when the computer is continuously powered on Integrated 8042 compatible keyboard controller By default, the 87306B 87306B interfaces are automatically configured by the BIOS during boot-up. You can also manually configure the interfaces with the BIOS Setup program. Chapter 3 describes the BIOS Setup program. 1.7.1 Floppy Controller The I/O controller is software compatible with the DP8473 DP8473 and 82077 floppy disk controllers. You can configure the floppy interface for 360 KB or 1.2 MB 5¼ inch media or for 720 KB, 1.2 MB, 1.44 MB, or 2.88 MB 3½ inch media with the BIOS Setup program. By default, the Floppy A interface is configured for 1.44 MB and Floppy B is disabled. A Setup option makes it possible to prevent a user from being able to write to a floppy drive. A driver is required for configuring the floppy interface for 1.2 MB 3.5-inch (3-mode floppy) operation. 1.7.2 Keyboard and Mouse Interface PS/2 keyboard and mouse connectors are located on the back panel side of the motherboard. The 5V lines to these connectors are protected with a PolySwitch circuit that acts much like a selfhealing fuse, re-establishing the connection after an over-current condition is removed. While this device eliminates the possibility of having to replace a fuse, you should still be sure to turn off the computer power before installing or removing a keyboard or mouse. The PC87306B PC87306B contains the AMI Megakey keyboard and mouse controller code that, besides providing traditional keyboard and mouse control functions, supports Power-On/Reset (POR) password protection. The POR password can be defined by the user via the Setup program. The keyboard controller also provides for the following "hot key" sequences: · · · 1.7.3 : Computer software reset. This sequence performs a software reset of the computer by jumping to the beginning of the BIOS code and running the POST operation. and : Turbo mode selection. sets the computer for de-turbo mode, emulating an 25 MHz AT, and sets the computer for turbo mode. Changing the Turbo mode may be prohibited by an operating system, or when the microprocessor is in Protected mode or virtual x86 mode under DOS. : A power down hot-key sequence takes advantage of the SMM features of the Pentium Processor to greatly reduce the computer's power consumption while maintaining the responsiveness necessary to service external interrupts. A security hot-key sequence provides password protection to the computer. Real-time clock, CMOS RAM and battery The integrated real-time clock (RTC) is DS1287 DS1287 and MC146818 MC146818 compatible and provides a time of day clock, 100-year calendar with alarm features. The RTC can be set via the BIOS Setup program. The RTC also supports 242-byte battery-backed CMOS RAM in two banks which is 13 TC430HX TC430HX ATX Motherboard Technical Product Specification reserved for BIOS use. The CMOS RAM can be set to specific values or cleared to the default values using the BIOS Setup program. Also, the CMOS RAM values can be cleared to the defaults by using a configuration jumper on the board. An external coin-cell style battery provides power to the RTC and CMOS memory. The battery has an estimated lifetime of three years if the computer is not plugged into the wall socket. When the computer is plugged in, power is supplied from the power supply's +5 V standby current to extend the life of the battery. 1.7.4 Infra-Red Support A 5-pin interface on the front panel I/O connector is provided to allow connection to a Hewlett Packard HSDSL-1000 HSDSL-1000 compatible Infra-red (IrDA) transmitter/receiver. For Consumer Ir, a Sharp GP1U58X GP1U58X (second sourced by Litton), Panasonic PNA4602M PNA4602M, ICX IRR538 IRR538 and ICX model IRR638 IRR638 or equivalent receiver module is required. Both modules can be connected/supported, however only one can be active at a time. Once the module is connected to the front panel I/O header, Serial port 2 can be re-directed to either the IrDA or Consumer Ir module. Once configured for IrDA, the user can transfer files to or from portable devices such as laptops, PDA's and printers using application software such as LapLink. The IrDA specification provides for data transfers at 115 Kbps from a distance of 1 meter. The Consumer Ir is receive only (for the motherboard) and can be used to control telephony functions and multimedia operation such as volume control, CD track change etc. 1.7.5 Parallel port A 25-pin D-Sub header is provided on the back panel for a multi-mode bi-directional parallel port. The Parallel port can be configured in the BIOS Setup as output only compatible mode, bi-directional mode, ECP or EPP modes. The highly flexible parallel port can also be assigned to I/O addresses 278H, 378H, or 3BCH and IRQs 5 or 7. Furthermore, a routable DMA scheme allows Plug and Play operating systems such as Windows 95 to route either DMA channels 1 or 3 to the parallel port for ECP mode. EPP BIOS support must be provided by a device driver or TSR. 1.8 Graphics Subsystem The TC430HX TC430HX motherboard is available with a factory option of an S3 Trio64 V+ or S3 ViRGE SVGA graphics. The TC430HX TC430HX motherboard supports the S3 media channel for HW MPEG. CAUTION When removing graphics memory from the on board sockets, use an approved SOJ IC removal tool, so that damage does not occur to the traces on the etched circuit board. 1.8.1 S3 ViRGE Graphics The NV430VX NV430VX motherboard is available with a factory option of an S3 ViRGE SVGA graphics controller with 2 MB of 50 ns EDO SOJ DRAM. The S3 ViRGE has a high performance 64-bit 2D/3D graphics engine and incorporates the S3 Streams Processor that enables the device to convert YUV formatted video data to RGB and provides acceleration for scaling the video display 14 Board Description without compromising picture quality or frame rate.

Hardware acceleration for graphics functions such as BitBLTs with ROPs, 2-point line draws, trapezoidal and polygon fills, clipping and cursor support provide high performance operation under Windows and other GUI environments. In addition, a fast linear addressing scheme based upon DCI reduces software overhead by mapping the display memory into the microprocessor's upper memory address space and permitting direct microprocessor access to the display memory. 15 TC430HX TC430HX ATX Motherboard Technical Product Specification Table 2.

Drivers for SCO UNIX are available from SCO. 1.9 Audio Subsystem The motherboard features a 16-bit stereo audio subsystem as a factory installed option. The audio subsystem is based upon the Yamaha YMF701 YMF701 OPL3-SA FM synthesizer. The OPL3-SA provides all the digital audio and analog mixing functions required for recording and playing of audio on personal computers. These functions include stereo analog-to-digital and digital-to-analog converters, analog mixing, anti-aliasing and reconstruction filters, line and microphone level inputs, and digital audio compression via selectable A-law / µlaw, and full digital control of all mixer and volume control functions. 16 Board Description 1.9.1 Yamaha OPL4-ML The Yamaha OPL4-ML wavetable is an option if the OPL3-SA is installed. The OPL4-ML is a ROM table containing live instrument sound samples. Wave synthesis results in richer and more realistic sounds then that of FM synthesis. If the OPL4-ML option is not installed, a wavetable upgrade connector header (J1F1) is installed allowing use of an ISA bus add in wavetable card. 1.9.2 SRS SRS Labs, Inc. Sound Retrieval System (SRS) technology enhanced audio is available as a factory installed option. SRS is a patented and licensed audio circuit that creates 3D spatial sound from conventional mono, stereo, or surround sound, using only two speakers. This is achieved by summing portions of the right channel audio into the left and vice versa, and does not require signal encoding/decoding, time delay or phase shift of the audio signal. The resultant effect is the creation of virtual speakers, which expands the audio image, creating a 3D sound experience, and eliminating the speakers as discrete point audio sources. Table 3.

The Powerman utility supplied for Windows 3.1x allows for soft-off as does the shutdown icon in Windows 95 Start menu. The BIOS will turn the computer power off when it receives the proper APM command from the OS. For example, Windows 95 will issue this APM command when the user selects "Shutdown the computer" option. APM must be enabled in the BIOS and OS in order for the soft-off feature to work correctly. If power to the computer is interrupted due to a power outage or the power cord being unplugged, when power is reapplied, the computer will return to the state it was in when the power was disconnected. If the computer was turned on when power was disconnected, the computer will turn back on when power is reapplied. 25 TC430HX TC430HX ATX Motherboard Technical Product Specification 1.10.13 Front panel Connectors The board provides header connectors to support functions typically located on the chassis bezel. Front panel features supported include: · · · · · · · Speaker Reset Sleep LED Hard drive activity LED Infra-red (IrDA) connector Sleep/Resume Power on J10K1 J10K1 SPKR SLEEP LED HD LED IR RESET PWR ON SLEEP OM04729A OM04729A Figure 4. Front Panel I/O Connectors 1.10.13.1 Speaker The external speaker provides error beep code information during the Power-On Self Test, if the computer cannot use the video interface. If there are no speakers plugged into the audio output jack, the audio output is redirected to the external speaker. 1.10.13.2 Reset This header can be connected to a momentary SPST type switch that is normally open. When the switch is closed, the computer will hard reset and run POST. 1.10.13.3 Sleep LED This header can be connected to an LED to provide a visual indicator for when the system power is turned on or when the system is in sleep mode. When the system is powered on, the LED will be continuously lit. When the system is in sleep mode, the LED will blink at 1 HZ. 1.10.13.4 Hard Drive Activity LED This header can be connected to an LED to provide a visual indicator for when an IDE hard drive connected to the onboard IDE controller is being read or written. 26 Board Description 1.10.13.5 Infra-Red (IrDA) Connector Serial port 2 can be configured to support an IrDA or Consumer Ir module via a front panel header connector. Once configured for IrDA, the user can transfer files to or from portable devices such as laptops, PDA's, and printers using application software such as LapLink. The IrDA specification provides for data transfers at 115 Kbps from a distance of 1 meter. Consumer Ir is typically used for remote control of telephony and multimedia functions. 1.10.13.6 Sleep/Resume When Advanced Power Management (APM) is activated in the BIOS and the Operating System's APM driver is loaded, Sleep mode (Stand-By) can be entered in one of three ways: an optional front panel "Sleep/Resume" button, a user defined keyboard hot key, or prolonged inactivity. The Sleep/Resume button is supported by a 2-pin header located on the front panel I/O connector. Closing the "Sleep" switch will generate an SMI (System Management Interrupt) to the processor which immediately goes into System Management Mode (SMM), the so called "Sleep" mode. The front panel "Sleep mode" switch must be a momentary two pin SPST type that is normally open. The function of the Sleep/Resume button can also be achieved via a keyboard hot-key sequence, or by a time-out of the inactivity timer. Both the keyboard hot-key and the inactivity timer are programmable in the BIOS Setup (timer is set to 10 minutes by default). To re-activate the computer, or "Resume", the user must press the sleep/resume button again, or use the keyboard or mouse. Mouse activity will only "wake up" the computer if a mouse driver is loaded. While the computer is in Stand-By or "sleep" mode it is fully capable of responding to and servicing external interrupts (such as incoming FAX) even though the monitor will only turn on if a user interrupt (keyboard/mouse) occurs as mentioned above. 1.10.13.7 Power On This header can be connected to a momentary SPST type switch that is normally open. When the switch is closed, the computer will power up and run POST. If the system is already powered up, closing the switch will power off the system. 27 TC430HX TC430HX ATX Motherboard Technical Product Specification 1.10.14 1.10.14.1 Audio Connectors CD-ROM Audio Input A four pin connector is provided for interfacing the audio output stream from a CD-ROM reader into the audio subsystem mixer. This connector is compatible with the typical cable that is supplied with CD-ROM readers for interfacing to audio add-in cards. 1.10.14.2 Wavetable Upgrade There are two different ways to provide hardware wavetable on this motherboard. The first is a manufacturing option to include the Yamaha OPL4 on the motherboard. The second is to use the 8-pin wavetable upgrade connector on the motherboard and install an ISA based wavetable upgrade card. This card fits into an ISA slot, and cables to the header such that it only uses the power pins of the ISA connector. 1.10.15 Back Panel Connectors The back panel provides external access to PS/2 style keyboard and mouse connectors, two Universal Serial Bus (USB) connectors, one serial port connector, one parallel port connector, a VGA connector, a MIDI/game port connector, and the external audio jacks.

The computer should then be turned off and the jumper should be returned to the 1-2 position to restore normal operation. This procedure should only be done if the user or administrative password has been forgotten. The password function is effectively disabled if this jumper is in the 2-3 position. Default is for the password to be enabled (1-2 position). 1.11.3 Clear CMOS (J10C1-A J10C1-A, Pins 4, 5, and 6) Allows CMOS settings to be reset to default values by moving the jumper from pins 4-5 to pins 5-6 and turning the computer on. When the computer reports that "NVRAM cleared by jumper", the computer can be turned off, and the jumper should be returned to the 4-5 position to restore normal operation. Default is for this jumper to be on pins 4-5. 1.11.4 Setup Access (J10C1-B J10C1-B, Pins 1, 2, and 3) Allows access to Setup program to be disabled by moving this jumper from the 1-2 position to the 2-3 position. Default is for access to Setup to be enabled (1-2 position). 1.11.5 Microprocessor Voltage (J5K1) This jumper block changes the output of the on-board voltage regulator. Pins 1-2 should be jumpered for processors that require standard voltage regulation. Pins 2-3 should be jumpered for processors that require the VRE specification. This jumper should not be changed by the user unless changing to a new processor type. Some upgrade processors may require a different setting. Check the processor's documentation for the correct setting.
