AMD PCnet Family Software
NDIS4 Miniport driver for Windows NT
Version 4.09a
What's new in this release
==========================
PCNET.EXE has been modified to display the correct path
for the service during installation of the driver.
Changes made for version 4.09
=============================
1. Support for Unattended Windows NT installation added to the default
OEMSETUP.INF file.
2. Added support for multiple switches for PermaNet Server Link Fault
Tolerance (LFT) feature.
3. OEMSETUP.INF file has been modified to fix a bug, appearing during
a fresh installation of Windows NT, which gave an error that the pcnet.exe
file is missing.
4. RC file has been changed so that the driver reports the correct version
information under both Windows NT and Windows 95.

DMI Instrumentation
for NDIS4 Miniport Driver and PermaNet Server Driver for Windows NT
DMI Instrumentation changes
==========================
1. The DMI instrumentation has been enhanced to support event generation.
This feature works with the PermaNet Server driver. When a failover
occurs and the backup adapter takes over the functions of the failed
adapter, a DMI indication is sent to the DMI Service Provider to
notify the user that the Primary adapter has failed. Similarly, if the
Primary Adapter comes back on line, network traffic is switched back
to the Primary adapter and another DMI notfication is issued.
2. The DMI component instrumentation now detects the presence of the
DMI service layer. So no messages (from the operating system) are
displayed if the service layer is absent.
3. DMI instrumentation gets automatically installed when the driver is
installed.
