GENERAL DESCRIPTION
The ISAnet evaluation kit meets the needs of customers working with embedded networking control applications using the Am79C961A PCnet-ISA II single-chip
Ethernet controller. The evaluation kit contains hardware, software, and documentation to facilitate the design of embedded networking control applications
based on the PCnet-ISA II controller.
The user should note there is a significant difference
between ISAnet evaluation adapter card used here and
the PCnet-ISA II evaluation adapter card used in the
PCnet-ISA II-KT/2 Evaluation Kit. While both adapter
cards are ISA-based adapter cards and both are based
on the Am79C961A PCnet-ISA II Ethernet controller,
the ISAnet evaluation adapter card is designed and
configured for shared memory and PIO operation
mode. The adapter card in the PCnet-ISA II-KT/2 evaluation kit is designed and configured for bus-mastering
operation mode.
The design of the ISAnet adapter card provides an
Ethernet feature that can be added to other platforms with
ISA slots to allow for system development in a shared
memory mode environment. In particular, the ISAnet
adapter card is ideal for use with AMD’s family of Élan
microcontrollers and their evaluation boards. This is
because the Élan family of microcontrollers, in particular,
ÉlanSC300 and ÉlanSC400 series of microcontrollers do

not support bus-mastering peripherals. With the addition
of the ISAnet adapter card, the user has a complete Élan/
PCnet-ISA II shared memory development environment.
For users who have already designed and implemented the hardware portion of their application based
on the PCnet-ISA II Ethernet controller and just need
the software driver and documentation, a package containing only the binary driver software and documentation is available from AMD’s Literature Distribution
(Order PID# 21450).
Software
Included in both the ISAnet evaluation kit and the software/
documentation only package, are a number of software
programs and utilities on a set of diskettes. The driver software diskette contains binary code for Novell DOS ODI and
NDIS 2.0 for DOS driver software. Source code for these
two drivers can be acquired from AMD upon completion
and execution of an license agreement form. The Request
for ISAnet Driver Source Code License Form is included in
the Quick-Start ISAnet User’s Brief. Send the completed
form to “AMD, ISAnet Driver Administration, M/S: 126, Systems Software Engineering.”
The utility diskette contains a variety of software programs including EESETUP and EE_DUMP for programming and examining the EEPROM. Also
included are diskettes containing electronic copies of
the schematics, bill of materials, layout artwork, and
Gerber files for the PCnet-ISA II shared memory
board. A diskette containing a number of utilities for
configuring and interfacing the PCnet-ISA II to the
ÉlanSC400 microcontroller concludes the diskette set.
CAUTION: The user is highly cautioned against using the binary driver software from the PCnet-ISA IIKT/2 Evaluation Kit on the ISAnet adapter card. It
will not function!
PCnet-ISA II Ethernet Controller
The Am79C961A PCnet-ISA II Ethernet controller, a
single-chip Ethernet controller, is a highly integrated
Ethernet controller with a built-in ISA bus and PHY
layer (Manchester Encoder/Decoder and 10BASE-T
transceiver). The PCnet-ISA II device can be used in either bus-mastering or shared memory mode. On the
ISAnet adapter card, the PCnet-ISA II device is configured for shared memory operation mode. The 16-bit
ISA interface makes an ideal straight-forward connection to an x86-style local bus. For more information
about the PCnet-ISA II controller, refer to the
Am79C961A PCnet-ISA II Data Sheet, PID#19364.
The PCnet-ISA II Ethernet controller is part of the
AMD PCnet family of single-chip Ethernet controllers
based on the original LANCE/CLANCE architecture.
Other members include the following: the Am79C965
PCnet-32 (for VL or other general x486, 32-bit bus
environments), the Am79C970A PCnet-PCI II device
and the Am79C971 PCnet-FAST device (for PCI bus
environments). Like the PCnet-ISA II controller, the
PCnet-32 and PCnet-PCI II devices are 10 Mbps
Ethernet controllers. The Am79C971 PCnet- FAST
device is a 10/100 Mbps Ethernet controller.
