The Ethernet/Cheapernet/IEEE 802.3 evaluation kit,
called the C-LANCE-AT-KT (Am2100 architecture), is a
design evaluation vehicle for AMD’s Ethernet chipset. It
is intended for use in IBM PC/AT or compatible machines, and represents a low component count, minimum board space, low cost networ k adapter
implementation. There are two versions of the card
available for evaluation, each optimized for a particular
medium. The C-LANCE-AT-KT/2 card supports the
1 0 B A S E 2 ( C h e a p e rn e t ) c o n n e c t i o n , w h i l e
theC-LANCE-AT-KT/2T card supports the 10BASE-T
(Twisted Pair) connection. Both versions have a standard AUI port (fully IEEE 802.3, Section 7, compliant)
for connecting to 10BASE5 (Ethernet) medium through
an external MAU. The choice of network media operation is jumper selectable.
Despite the card’s low cost, it is still a high performance
design that takes full advantage of the PC/AT
multi-master I/O bus. When installed in a host machine,
the system becomes a platform upon which to evaluate
network hardware and to develop software for a complete node processor. The software designer can take
advantage of the many tools available for the PC/
AT-compilers, assemblers, and debuggers.
The C-LANCE-AT-KT comes with a floppy diskette of
software programs. The software includes a high-level
demonstration program, a low-level driver/monitor,
Packet Driver (version 10.3), driver object code for NetWare ODI, NDIS 2.01, NDIS 3.0, Artisoft LANtastic/AI,
and Streams (for SCO UNIX). The demonstration program contains an ISO data link layer with a menu
driven interface which allows the user to assign physical and logical addresses, establish connections, and
send and receive messages. The driver/monitor lets
t h e u s e r v i ew a n d c h a n g e t h e c o n t e n t s o f
theC-LANCE’s registers, the memory resident Initialization Block, and the data buffer Descriptor Rings. The
program also allows the designer to establish loops for
hardware data probing. The Packet Driver (source
code and object code) is included as a sample
C-LANCE driver in 80x86 assembly language. The Novell NetWare object code, as well as the other drivers,
transforms the C-LANCE-AT-KT into a cost effective,
competitive, and manufacturing-ready commercial
board level product. This allows the user to evaluate
the performance of the AMD Ethernet chipset in a real
PC LAN system.
In addition to the board and the software diskette,
theC-LANCE-AT-KT kit comes with a user’s manual including device specifications, device application notes,
the Am2100/Am1500T Network Driver Installation
Guide, C-LANCE device datasheet, and cable hook-up
