In addition to the CPU, this board houses the bridge battery and speaker. It controls important functions including power management, direct drive bus in- terface and memory management. I/O Board The I/O board (G8TUP) contains peripheral subsystems including serial, parallel and video ports. It is located underneath the sound board. I/O board specifications are listed in Table Section 1-8 at the end of this section. Sound Board The sound board (G8UNA) provides the NEC Versa 4000 series system with its audio ca- pabilities via line-in/line-out jacks, and headphone/microphone jacks. It is situated on top of the I/O board., 1-4 Technical Information Infrared (IR) Front Assembly, Rear Assembly Two IR assemblies are connected to the I/O board via connectors P10 and P11 respectively. One is located on the front of the NEC Versa, the second one is located on the rear of the NEC Versa. Each IR assembly consists of a small board with infrared LEDs. The board allows the NEC Versa 4000 series computer to communicate with other infrared-ready computers. For ex- ample, the infrared ports allow the user to transfer files between the NEC Versa and an IR- equipped desktop, or print to an IR-equipped printer without using cables. The NEC Versa 4000 series system ships with the rear IR assembly disabled and the front IR assembly disabled. When the NEC Versa 4000 is docked to the optional NEC Versa Docking Station 4000, the rear IR assembly is automatically disabled, and the front enabled. Battery Pack The system uses a rechargeable lithium-ion (Li-ION) battery as its transient power source. The battery pack installs in the compartment next to the standard diskette drive on the bot- tom of the Versa 4000. The battery uses 10.8 volts with a 2500 mAh capacity. The battery pack powers the NEC Versa 4000 for approximately 5 hours with Power Man- agement or 2.5 hours without Power management. In addition, the battery pack lets the user know how much battery power is available via the LEDs on the front of the system, or the battery gas gauge in the power panel. When battery power is getting low, connect the AC adapter to a wall outlet and recharge the battery. It takes 2.5 hours to recharge the battery pack when the system is powered off, (Quick Charge). It takes 2.5 hours to recharge the battery while the system is powered on, (Normal Charge). CMOS Battery The lithium battery (3.0 Volts, 280 mAh capacity) is attached to connector P12 on the CPU board. It provides battery backup and prevents data loss in the system’s complementary metal oxide semiconductor (CMOS) RAM. This memory area contains information on the system’s configuration like date, time, drives, and memory. The CMOS battery lasts ap- proximately two years. Bridge Battery The bridge battery saves the memory contents and system status for up to 5 minutes while in Suspend mode. It is connected to the CPU board via P8. The AC adapter maintains volt- age in the bridge battery when the system is powered on or off. The bridge battery provides 6 Volts, 60 mAH., Technical Information 1-5 PCMCIA Slots The Versa 4000 providesa5volt, or 3.3 volt interface for either two Type I/Type II PCMCIA cards, or one Type III PCMCIA card. Diskette Drive and the NEC VersaBay II A standard 1.44-MB diskette drive comes installed in the VersaBay II slot on the front of the system. The VersaBay II expansion slot allows the user to replace the standard diskette drive with a number of different NEC options including a CD-ROM reader, a second bat- tery pack, or an additional hard disk drive using the release latches on the bottom of the unit. Keyboard The built-in, 83-key keyboard (U.S) or 79-key keyboard (UK and Germany) uses the stan- dard QWERTY format. The keyboard provides 12 function keys and 8 cursor control keys, with an Fn key for ROM-based key functions. The numeric keypad is embedded in the stan- dard key layout. NEC VersaGlide The NEC VersaGlide is a built-in mechanism that functions as the system’s mouse. It con- trols the on-screen pointer (cursor). To use the VersaGlide, glide your finger across the NEC VersaGlide pad, and the cursor follows. The buttons on either side of the NEC Ver- saGlide allow the user to select or deselect menu items. Tap and double-tap are supported on the VersaGlide pad. The NEC VersaGlide is the system's default pointing device unless a PS/2 mouse is in- stalled. If an external mouse is installed, then the NEC VersaGlide is deactivated. A serial mouse is not supported. SYSTEM MEMORY The system board provides 8-MB of standard random access memory (RAM).The NEC Versa 4000 operates with 4 banks. Banks 0 to 1 are used for the standard 8-MB (with in- terleaved access support). Banks 2 to 4 are used for memory expansion (without interleaved access support). Optional memory cards with a value of 4-, 8-, 16-, or 32-MB can be added to increase sys- tem memory up to a maximum of 40-MB. In addition, 256 KB of read-only memory (ROM), 1 x 28F020, enables the system BIOS to be flashed. Cache RAM is available with L1 write-back access support providing 8 KB for code, 8 KB for data. L2 write-through access support providing 256 KB., 1-6 Technical Information Memory Map The system supports system and video shadowing, both controlled through complementary metal oxide semiconductor (CMOS).

It uses a 25-pin D-subconnector. The port is located on the system's rear panel. The modes of operation available for a PC87334 chip are compatibility mode nibble mode byte mode Enhanced Capabilitied Port (ECP) Enhanced Parallel Port (EPP). The user selects between three parallel interface modes using Auto Setup. These include unidirectional, bidirectional or enhanced. Unidirectional mode sends data output from the standard ISA port only. Bidirectional mode sends data using the standard ISA port or PS/2 technology. Enhanced mode enables high speed data transmission to occur using either the unidirectional or bidirectional modes., 1-12 Technical Information The parallel port address is 378h and the interrupt level is IRQ07. Pin locations for the par- allel interface are listed in Appendix A. SERIAL INTERFACE The RS-232C serial port is a 9-pin connector on the system’s rear panel. The serial port consists of a 16550 compatible serial port controller with a programmable baud rate up to 115,200 bps. The serial port connects an RS-232C device or an external modem. The serial port address is 3F8h and the interrupt level is IRQ04. NEC VERSA 4000 SERIES CHIP SET Refer to Table Section 1-5 for a quick summary of the chip types used in the system.

The CPU has on-chip dual-processing, a local multiprocessor interrupt controller, and power management features. NEC adopted the chip specifically for its pipelined Floating Point Unit (FPU), and local interrupt management., Technical Information 1-13 Cache Controller, Address Logic, Data Controller The Golden Gate PT80C732 and PT80C733 Pico Power controller provides a dual-chip structure that connect the Pentium processor to the industry-standard 486 bus. The chip in- creases data reliability by integrating the following: 8-level write buffer extends battery life and efficient thermal management improved performance for DRAM and VL bus peripherals. System Logic, IDE Interface, Peripheral Controller The PT86C718 Pico Power chip consists of a 176-pin thin-quad flat-package. This chip controller supports fast graphics and I/O processing. The system logic controller adds the following features: built-in level 2 cache controller integrated active power management integrated battery management high performance DRAM controller. Flash ROM The N28F020 flash ROM is a 32-pin, plastic lead chip carrier (PLCC). The chip allows easy updates to the system's BIOS if needed. More specifically, the ROM is flashed electroni- cally, installing the latest BIOS revisions to the system. It is possible to reprogram the BIOS up to 100,000 times. See Section 2, Setup and Operation, for BIOS update procedures. The N28F020 provides the system upgrade capability as well as the following: 256 KB memory Quick-Pulse Programming Algorithm 150 nanoseconds (ns) maximum access time ETOX Nonvolatile flash technology CMOS low power consumption, 1-14 Technical Information ROM BIOS The system uses a Flash ROM known as the system's ROM BIOS to store machine lan- guage programs. The BIOS size is 256 KB, consisting of the system utility (PCMCIA, Auto Setup), system BIOS, video BIOS, and power management. The BIOS programs execute the power-on self-test (POST), initialize CPU controllers, and interact with the LCD indicator panel, diskette drive, hard drive, communication devices and peripherals. The system BIOS also contains Auto Setup and provides VGA controller support. The ROM BIOS is copied into RAM (shadowing) for optimum performance. The ROM BIOS contains both the system and video BIOS. The system BIOS is located in the upper portion of the device, video BIOS is located in the lower portion. System BIOS is located between F000h-FFFFh. The BIOS often changes after the product release to provide enhanced features or bug fixes. To acquire the latest BIOS release, the ROM is flashed electronically allowing the BIOS update to occur without removing the ROM. See Section 2, Setup and Operation, for BIOS upgrade procedures. VGA Controller The video architecture is maintained using the C&T65545B1-5 or C&T65545B2-H Con- troller and support logic. The controller supports video standards including EGA and CGA. This powerful circuitry provides the following features for the system via the controller and LCD: 1-MB VRAM true-color and high-color display capability with 640 x 480 resolution supports external CRT resolutions up to 1024 x 768 hardware windows acceleration bit boundary block transfer simultaneous LCD/CRT display in 640 x 480 VGA display mode optional frame memory high resolution graphics support., Technical Information 1-15 Video Controller Architecture The video controller architecture is broken down into several modules. The five significant modules include the sequencer, CRT controller, graphics controller, attribute controller and dithering engine. For example, the sequencer manages CPU and display memory timing. The CRT controller controls sync and timing signals. The graphics controller permits the flow of communication between the CPU data bus and the 32-bit internal data bus. The attribute controller pro- duces a 4-bit wide video data stream that refreshes the display. Diskette Controller, Serial Interface, Parallel Interface The PC87334 chip is a 100-pin plastic Thin Quad Flat Plastic (TQFP) chip. The controller changes 8-bit parallel data into serial data and writes the data to the diskette. Conversely, the serial data is transmitted from the diskette into parallel data, where it remains until the read operation takes place. Additional PC8733 chip operations include: ISA compatibility low-power CMOS with enhanced power-down mode Keyboard Controller The keyboard controller (M38813E4HP) supports a PS/2-style keyboard, mouse and secu- rity features such as keyboard hot keys and password. Refer to Appendix A for keyboard interface connector pin assignments. When data is written to the output buffer, the controller generates an interrupt, and requests the CPU to receive the data. The controller automatically adds an even parity bit to the data sent and waits for a response. The device must acknowledge that the data was successfully received by sending a response to the controller for each byte of data received. PCMCIA Controller The controller (PD6722) interfaces with the ISA bus, PCMCIA card socket and configura- tion registers to provide: memory address mapping, I/O address mapping power management for each PCMICA card socket, controlled through power and RESETDRV control registers the elimination of interrupt conflicts using interrupt steering., 1-16 Technical Information Interrupt Controllers Using interrupts, it is possible to change the code sequence. To change the sequence, reas- sign the interrupt-levels. Fifteen interrupts can be used with a cascade connection of 8259INTC x 2. Interrupt-level assignments 0 through 15 are listed in Table Section 1-6, in order of de- creasing priority.

The CPU implements a System Management Interrupt (SMI) function that works transpar- ently with the operating system and application software. When activated, the processor mode changes to real mode. Unique “SM-RAM” containing power management software is mapped at address 30000h-3FFFFh. This activity is inherent to the system and does not re- quire any adjustment to the operating system or application software. The power management program is located in ROM at location EA000h-0EFFFh. In on- board DRAM, the software is physically allocated at 0D0000h-0DFFFFh. Use Auto Setup to select specific power management options. For information on how to select these options, see Section 2. NOTE: Some power management features are unavailable when an NEC docking station is con- nected. System Power Management The system power management consists of the following operation modes. These modes are: Active Mode In active mode, the system uses maximum power. It operates with the default clock speed. The system continues to run at this speeds unless overwritten by the power management features. Suspend Mode When the system is powered on, but not in use it enters into Automatic Suspend mode after a specified amount of time (default timeout is 5 minutes). This shut-down mechanism conserves system power while allowing the user to return to complete the work at any time. Or, the system can be put into Suspend mode using the suspend button. Press the suspend button to activate Suspend mode; press it again to resume active mode. Suspend mode causes the CPU power down, local devices to shut down, and register values to be stored in RAM. System RAM is put into a slow refresh state., 1-18 Technical Information Local Power Management Use Auto Setup to select one of four power management settings for local devices. These include Longest Battery Life, Highest Performance, Custom Setup, and Power Management Off. The power management levels are also available during AC operation. The NEC Versa 4000 computer ships with Longest Battery Life as the default power management setting. See Section 2 for specific procedures on using Auto Setup to select the power management settings. When set to Longest Battery Life, CMOS will set local device timeout values, a local stand- by timeout value, and a suspend timeout value to ensure the longest battery life. The High- est Performance setting selects CMOS values that will provide minimal energy savings and a shorter battery life. The custom settings enable end-users to set the timeout values of their choice. The Power Management Off selection terminates all power management timers. Local device timers in the system control power consumption in the LCD and Hard Disk Drive. Table Section 1-7 shows NEC Versa 4000 series Maximum Performance default power management timers. Table Section 1-7 Maximum Performance Default Settings P ower Management Automatic Suspend H ard Disk Timer L CD Panel Timer Mode Longest Battery Life10minutes30seconds 2 minutes Highest Performance30minutes10minutes10minutes Custom15minutes15seconds 2 minutes PLUG AND PLAY The NEC Versa 4000 has a Plug and Play functionality. This means you can suspend the system, add an external keyboard, mouse, or monitor, and when you resume working, the NEC Versa 4000 recognizes the devices that have been connected to it. Similarly, you can remove external devices in Suspend mode and the NEC Versa 4000 notices the difference when resumed. NOTE: A plug and play operating system and BIOS are required for this option to work., Technical Information 1-19
