Section 1
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

unit, 8-watt speakers, and a microphone.

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.
