Technical Information external connectors providing an interface for the following external devices: video graphics array (VGA)-compatible monitor ® personal system/2 (PS/2 )-style mouse PS/2-style keyboard PS/2, Enhanced Parallel Port (EPP) and enhanced capabilities port (ECP) are supported for the parallel printer two buffered serial ports Table Section 1-1 lists the major chips on the system board.
Page 22 Technical Information Chipset The Image P90E and Image P100E computers use the Intel Neptune II chipset, which consists of the PCI cache and memory controller (PCMC), two local bus accelerators (LBXs), the PCI EISA bridge component (PCEB), and the EISA system component (ESC). Together these five chips control the cache memory, the EISA bus, the BIOS Flash ROM, the keyboard controller, and the I/O controller.
Page 23: Pci-Eisa Bridge Component
Technical Information PCI-EISA Bridge Component (PCEB) The PCEB is one of the two chips that connect the PCI bus to to the EISA bus. The PCEB translates bus protocols from EISA to PCI and vice versa. Extensive buffering of both the PCI and EISA interface allows for concurrent operations.
Page 24: Host Bus
Technical Information Figure Section 1-2 Component Block Diagram Host Bus The host bus consists of a 32-bit address bus (A<31..0>), a 64-bit data bus (D<63..0>), and control circuitry. The host bus interfaces the processor to the PCI cache and memory controller (PCMC), the local bus accelerators (LBXs), and the secondary (L2) cache.
Page 25: Pci Bus
Technical Information PCI Bus The PCI bus consists of a multiplexed address and data bus (AD<31..0>) and control circuitry. The PCI bus allows industry-standard PCI option boards to interface to the system. The PCMC and LBXs link the PCI bus to the host bus, and PCI EISA bridge component (PCEB) links the PCI bus to the EISA bus.
Page 26: Secondary Cache
1-10 Technical Information The dual processor upgrade option is installed in a 320-pin PGA, zero-insertion-force (ZIF) socket on the system board. Secondary Cache The 16-KB primary cache (8 KB data and 8 KB instruction) is integrated into the processor. The system board also provides 256 KB of 9-ns, synchronous secondary cache memory that is external to the processor.
Page 27 128K granularity for ROM reads and 64K granularity for flashing. NEC Port 0C12h bits 6 and 7 map each of the four 64K byte chunks of the ROM to the FXXXX range. ACU access is controlled by the system BIOS code and is generally not accessible in ISA space.
Page 28: On-Board Peripherals
1-12 Technical Information Flash ROM programming is supported only in the 0F0000h – 0FFFFh area. The system and Video BIOS area of the Flash ROM (upper 64 KB) can be erased, programmed, and verified normally with the RPG0 bit set low (to 0). To erase, program, and verify the SCSI BIOS and ACU area (lower 64 bits) the RPG0 bit must be set high (to 1).
Page 29: Real-Time Clock (Rtc)
The I/O ports implemented by the system I/O controller are not listed. Refer to the SMC FDC37C665 data sheets for a detailed description of the system I/O controller ports. In addition, keyboard controller registers (with the exception of the keyboard status register) are documented in the NEC PS/2 Style Keyboard Controller release notes.

Page 38: Interrupt Controller
1-22 Technical Information Interrupt Controller The interrupt controller is implemented on the EISA system component (ESC) and operates as an interrupt manager for the entire system environment. The controller accepts requests from peripherals, issues interrupt requests to the processor, resolves interrupt priorities, and provides vectors for the processor to determine which interrupt routine to execute.
Page 39: Video Controller
Technical Information 1-23 Video Controller The Tseng W32P PCI graphics controller is a PCI local bus video controller that delivers a 32-bit PCI-bus interface with the CPU. It features a graphic user interface (GUI) accelerator, and advanced features for imaging and multimedia markets. Multimedia and imaging are enhanced through the inclusion of an unique Image Memory Access (IMA) port that allows direct access to the frame buffer at high speed.

The PCI-bus supports burst modes that send large chunks of data across the bus, allowing fast displays of high- resolution images.
Page 43: Serial Interface
Technical Information 1-27 Serial Interface The system has two standard serial ports. The serial ports support the standard RS-232C interface. The interrupt is selectable via Setup. Serial interface signals are output through the system board's 9-pin, D-subconnector. The connectors are located at the rear of the system unit.

Page 77: Eisa Configuration Utility
2-32 Setup and Operation EISA Configuration Utility The ECU program comes on a diskette that ships with the computer and is required for EISA configuration. The ECU provides a detailed view of the system configuration and allows you to make system configuration changes when you add, move, or remove an EISA or ISA expansion board.
Page 78: When To Use The Ecu
The ECU requires a cold boot each time you load it. Power on the system. After performing its Power-On Self-Test, the system loads and starts the ECU. An ECU preparation screen appears followed by the NEC logo screen and the Main Menu (see Figure Section 2-4).

Page 80: Configure Computer Or Peripheral Devices
Setup and Operation 2-35 Configure Computer or Peripheral Devices Select the “Configure Computer or Peripheral Devices” option under the following cir- cumstances: you are setting up the system for the first time the “Invalid Configuration Information” message appears at power-on. If this message appears, run the Setup utility to correct any configuration errors.
Page 81 2-36 Setup and Operation Step 3: View or edit details — lets you view and change system board settings. You must select this step when you are setting up the system for the first time. Step 4: Examine switches or print report — allows you to view the required switch and jumper settings of a particular board.
Page 82 Setup and Operation 2-37 Step 2: Add or Remove Boards Select Step 2 whenever you install or remove any EISA boards or ISA boards with CFG files from the system. NOTE: If you are adding a EISA board to your system, first install the board.
Page 83 2-38 Setup and Operation In the rare event that the CFG file on the ECU diskette is newer, the system displays an Over- Write Current File message. In this case, press to cancel. If a board is not displayed and you did not load a configuration file for it, go to the next step.
Page 84 Setup and Operation 2-39 NOTE: If a CFG file comes with your board and a CFG file already exists on the ECU disk- ette, you still need to copy the CFG file from the option configuration diskette (see “Maintain System Configuration Diskette” in this section). This ensures that the system uses the latest ver- sion of the file.
