Technical Information

This section describes hardware features and components that are specific to the

PowerMate®Ve ETC Series of NEC PowerMate Ve Series computers. For information

that is general to all PowerMate Ve Series computers, see the PowerMate Ve Series Service

and Reference Manual (part number 819-181528-000).

SYSTEM OVERVIEW

1-2 Technical Information

SIMM UPGRADE

PowerMate Ve ETC Series system configurations come with 16 MB of main system

memory. Four sockets on the system board support up to 128 MB of high-speed memory

using the following industry-standard, tin-plated, single in-line memory modules (SIMMs):

NOTE: You may install 60-ns, parity or

nonparity, extended data output (EDO) SIMMs

into the SIMM sockets.



1-MB by 32- or 36-bit (4-MB stick)



2-MB by 32- or 36-bit (8-MB stick)



4-MB by 32- or 36-bit (16-MB stick)



8-MB by 32- or 36-bit (32-MB stick).

CAUTION: To avoid corrosion between

different metals, only use tin-plated SIMM sticks.

The system board can use 64-MB SIMMs (16-MB by 32- or 36-bit), but these SIMMs are

not supported by NECCSD for the PowerMate Ve ETC Series.

Performing Memory Upgrades

Upgrade system memory as follows:



locate memory sockets on system board



check installed system memory



install SIMMs.

Locating SIMM Sockets.

Remove the system unit cover and locate the six SIMM sockets on the system board (see

Section 3 of the PowerMate Ve Series Service and Reference Manual).

If any cables block access to the SIMM sockets, label and disconnect them. If any boards

block access to the sockets, remove them.

Checking System Memory

Use Table 1-2 to check the memory installed in the system and determine the SIMM

configuration needed to increase memory.

Technical Information 1-3

NOTE: SIMM memory must be installed in

pairs of the same memory type.

Installing SIMMS

After determining the system memory upgrade path, install SIMMs using the installation

procedure provided in Section 3 of the PowerMate Ve Series Service and Reference

Manual.

1-4 Technical Information

INTERRUPT CONTROLLER

The interrupt controller operates as an interrupt manager for the entire AT 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. The interrupt controller has priority

assignment modes that can be reconfigured at any time during system operations.

The interrupt levels are described in Table 1-3. Interrupt-level assignments 0 through 15 are

in order of decreasing priority. See Section 2 of the PowerMate Ve Series Service and

Reference Manual for information on changing the interrupts using Setup.

Table 1-3 Interrupt Level Assignments

Interrupt Assignment

IRQ 0 Counter/Timer

IRQ 1 Keyboard

IRQ 2(9) Cascade (INT output from slave)

IRQ 3 COM2 and COM4

IRQ 4 COM1 and COM3

IRQ 5 Parallel Port 2/Audio (if present)

IRQ 6 Diskette Drive Controller

IRQ 7 Parallel Port 1

IRQ 8 Real-time clock

IRQ 10 Available/Audio (if present)

IRQ 11 Network Interface Board

IRQ 12 PS/2 mouse

IRQ 13 Coprocessor

IRQ 14* Primary IDE

IRQ 15* Secondary IDE

Technical Information 1-5

INTEGRATED GRAPHICS

PowerMate Ve ETC Series computers have an SiS 6205 PCI graphics and video controller

integrated on the system board. State of the art techniques are used for optimizing

performance in computer graphic intensive applications and graphical user interfaces (GUI).

PowerMate Ve ETC Series systems have 1 MB of video DRAM on the system board. For

information about graphics features and video support, see Section 1 of the PowerMate Ve

Series Service and Reference Manual.

NETWORK INTERFACE

The computer comes equipped with a network interface board installed in one of the

expansion slots in the system unit. The three connectors on the board allow connection to

an Ethernet network and communication with other computers. Access to the connectors is

provided at the rear of the system unit. Figure 1-1 shows the location of the network

interface board and the three connectors. For more information, see Section 2 of this

addendum.
