In addition, the CRT port on the system's rear panel allows the user to connect an optional monochrome or color external display to the system. The computer supports the LCD and external display simultaneously. Power-saving features for controlling the LCD's backlighting include the ROM-based hot key Fn F5, and Auto Setup power management settings. See Section 2, Setup and Operation, for information on using these settings. In addition, the automatic LCD status sense feature conserves the backlight. When the LCD is closed the backlight shuts off, saving battery power.

System Board
The system board (G8TZL) is the primary component in the system. It contains I/O subsystems and houses the Intel® 486 DX4-75 chip (75 Mhz internal, 50 Mhz external). The chip controls important functions including power management, direct drive bus interface and memory management. System board specifications are listed in Table Section 2-8 at the end of this section.

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 diskette drive assembly. The battery uses 14.4 volts with a 2700 mAh capacity. The battery pack powers the Versa 2000 for up to approximately four hours under power management, and two 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 Windows. When battery power is getting low, connect the AC adapter to a wall outlet and recharge the battery. It takes 1.6 hours to recharge the battery pack when the system is powered off. It takes 6 to 9 hours to recharge the battery while the system is powered on.

CMOS Battery
The lithium battery (3.6 Volts, 1000 mAh capacity) is connected to CN17A on the system 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 approximately 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 system board via CN 13. The AC adapter maintains voltage in the bridge battery when the system is powered on or off. The bridge battery provides 10 Volts, 30 mAH.

PCMCIA Slots
The Versa 2000 provides a 3.3 volt interface for either two Type I/Type II PCMCIA cards, or one Type III PCMCIA card.

Keyboard
The built-in, 83-key keyboard (U.S) or 79-key keyboard (UK and Germany) uses the standard 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 standard key layout.

NEC VersaGlide
The NEC VersaGlide is a built-in mechanism that functions as the system's mouse. It controls 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 VersaGlide allow the user to select or deselect menu items. Double-tap is also supported on the VersaGlide pad. The NEC VersaGlide is the system's default pointing device unless a PS/2 mouse is installed. If an external mouse is installed, then the NEC VersaGlide is deactivated. A serial mouse is not supported.

SYSTEM MEMORY
The system board provides either 4- or 8-MB of standard random access memory (RAM). Base memory is 640 KB and extended memory is 3072 or 7168 KB (interleaved), depending on the system model. Optional memory cards with a value of 4-, 8-, or 16-MB can be added to increase system memory up to a maximum of 36- or 40-MB. In addition, 256 KB of read-only memory (ROM), 1 x 28F020, enables the system BIOS to be flashed.

Memory Map
The system supports system and video shadowing, both controlled through complementary metal oxide semiconductor (CMOS). The system supports BIOS as a cacheable area with write protection. Table Section 2-1 lists the system's memory map. To view a more complete breakdown, and to determine available space for the addition of drivers etc., type MSD at the DOS prompt and press Enter.

The system uses a Flash ROM known as the system's ROM BIOS to store machine language programs. The BIOS size is 256 KB, which consists of 96 KB system utility (PCMCIA, Auto Setup), 64 KB system BIOS, 32 KB video BIOS, 32 KB power management and 32 KB reserved. 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.

Peripheral Controller
The PT86C718 chip controls the Peripheral Controller, IDE Interface, and Interrupt Multiplexer. The chip integrates performance and power-saving features while providing the following: 8-level 64-bit write buffer to VL bus !" interrupt !" reset !" multiplexing logic logic.

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 produces a 4-bit wide video data stream that refreshes the display.

Diskette Controller, Serial Interface, Parallel Interface
The PC8733 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: compatibility with ISA, EISA, and Micro channel architectures !" low-power !" supports !" CMOS with enhanced power-down mode new 2 Mbps tape drives

Keyboard Controller
The keyboard controller (M5M44260ATP-7S) supports a PS/2-style keyboard, mouse and security 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 (IRQ01 or IRQ12) 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 (CL-PD6720) interfaces with the ISA bus, PCMCIA card socket and configuration registers to provide: memory address !" mapping, I/O address mapping

POWER MANAGEMENT OVERVIEW
The Versa 2000 series system uses power management features to prolong system battery life. The CPU implements a System Management Interrupt (SMI) function that works transparently 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 require any adjustment to the operating system or application software. The power management program is located in ROM at location EA000h-0EFFFh. In onboard 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 connected.

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 (75 MHz). The system continues to run at this speeds unless overwritten by the power management features. 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 10 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/Resume switch. Slide the switch to activate Suspend mode; slide again to resume active mode. Suspend mode causes the CPU clock to stop, local devices to shut down, and register values to be stored in RAM. System RAM is put into a slow refresh state.

Suspend !"

Local Power Management
Use Auto Setup to select one of four power management settings for local devices. These include Longest Battery Life, Personal Setup, Maximum Performance and Off. The power management levels are also available during AC operation. 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 Personal Setup setting enables end-users to set the timeout values of their choice. The Maximum Performance setting selects CMOS values that will provide minimal energy savings and a shorter battery life. The Off selection terminates all power management timers. Local device timers in the system control power consumption in the LCD and Hard Disk Drive.

PLUG AND PLAY
The NEC Versa 2000 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 2000 recognizes the devices that have been connected to it. Similarly, you can remove external devices in Suspend mode and the NEC Versa 2000 notices the difference when resumed. NOTE: A plug and play operating system and BIOS are required for this option to work.
