Board
2.1 Introduction
The DEC EtherWORKS Turbo board has a switch pack containing
12 switches that enable the board to operate in a configuration
without interference with the other boards in your computer. This
chapter describes how to change the settings on the switch pack.
If you have many add-on options in your system, you may have to
change the interrupt request (IRQ) line, the I/O address setting,
or the memory address setting on the DEC EtherWORKS Turbo
board to create a compatible operating set.
2.2 Default Settings
The DEC EtherWORKS Turbo board is shipped with the switches
preselected (default settings) to work in most installations. These
settings are shown in Table 2–1 and illustrated in Figure 2–1.

SW3 and SW4 select the size of the system memory space the
DEC EtherWORKS Turbo board uses. Table 2–2 lists six possible
memory addressing ranges and the switch settings that select
them.
Only one adapter can be set to use a given memory addressing
range. Check the documentation supplied with your personal
computer and other adapters to determine memory address
requirements. If the other adapters in your computer use memory
addressing ranges that conflict with one of these ranges, select a
range that is unused.

Board 2–5
The DEC EtherWORKS Turbo board works best when the entire
64 Kbytes of network buffer memory is enabled for its operation.
Some adapter boards and system configurations do not permit
the allocation of this amount of memory. Network performance
is slower when you select 32 Kbytes, but you can use the DEC
EtherWORKS Turbo board in configurations where address space
is at a premium.
Example:
Figure 2–2 shows the settings for SW1 through SW4 that
select a buffer size of 32 Kbytes in the C8000 - CFFFF (hex)
system memory addressing range.

GeneralInformation
A.1 Introduction
The DEC EtherWORKS Turbo board lets you integrate IBM-AT
compatible computers into a network. After installing a DEC
EtherWORKS Turbo board, you can use various network software
products to integrate the computer into a network.
You can install a DEC EtherWORKS Turbo board in any IBM-AT
or a computer that has an IBM-AT compatible bus.
You can connect the DEC EtherWORKS Turbo board to either a
ThinWire network or a ThickWire network. You cannot, however,
connect the DEC EtherWORKS Turbo board to both kinds of
networks at the same time.
A.2 Physical Description
The DEC EtherWORKS Turbo board is a half-length IBM AT
form-factor board that uses the full 16-bit bus connector.
The board measures 17.2 cm x 10.8 cm (6.75 inches x 4.25 inches);
the length to the end of the connector is 18.7 cm (7.38 inches).
A.2.1 Functional Components
The major functional blocks on the DEC EtherWORKS Turbo
board are as follows:
• Ethernet network protocol controller (LANCE)
• ThinWire (BNC connector) network interface
• Standard Ethernet ThickWire (DB-15S connector) network
interface
A–1
A–2 General Information
• Diagnostics and remote-boot ROM - 16 Kbytes (optional)
• Network buffer RAM - 64 Kbytes
• Ethernet hardware address ROM
A.2.2 LED
There is one light emitting diode (LED) on the mounting bracket
that displays the operating status of the DEC EtherWORKS
Turbo board. The amber LED comes on during power-up testing
and stays on if the test discovers a fault. Chapter 3 contains
additional information on the LED.
A.2.3 Environmental Requirements
The environmental (temperature and humidity) requirements for
the DEC EtherWORKS Turbo board are the same as for your
IBM-AT personal computer.
A.3 System Specifications
The DEC EtherWORKS Turbo board operates correctly at an
I/O channel bus speed of 10 MHz maximum. Table A–1 lists the
system specifications of the board.

Installingan Option ROM
B.1 Introduction
The ROM chip is optional on the DEC EtherWORKS Turbo
board and is not required for correct operation. If you purchased
the DEC EtherWORKS Turbo board from Digital (part number
DE200), then the board already has the option ROM installed.
CAUTION
Static electricity can damage printed circuit boards and
chips. It is strongly recommended that a grounded wrist
strap and grounded work-surface-to-earth ground be used
when handling these components.
If your configuration requires that the option ROM chip be
installed, use the following procedure to install it.

B–2 Installing an Option ROM
B.2 ROM Installation Procedure
CAUTION
Improper insertion of the ROM chip can damage the board.
1. Note the location of the notch!on the silk screen
surrounding the ROM socket (Figure B–1).
2. Be sure that the notch on the ROM"aligns with the notch
on the silk screen and the socket.
3. Align the pins on the chip and press from side to side until the
chip is fully seated.
