Push installation for Windows 95
You can set up a server-based push installation of Windows 95 as defined in the
Microsoft Windows 95 Resource Kit. You'll need to follow additional steps for the
Combo card. See the W9XPUSH.TXT readme file in the x:\ethernet\push directory
in the drivers CD.
Advanced adapter features
To access the advanced features of the adapter, do as follows:
The Combo card has following advanced features:

802.1p/802.1Q Tagging
IEEE 802.1p is a new IEEE standard for tagging packets— that is, assigning packets
priorities. Each packet is tagged with four additional bytes, which increase its size
and indicate its priority—from 0 (low) to 7 (high). This process is called priority
packet tagging or traffic class expediting. It enables the adapter, working with the
switches and routers in the network, to send packets with higher priorities first.
To use priority packet tagging, your network infrastructure—specifically, the routing
devices that receive and transfer packets, and the adapters for those devices—must
support 802.1 p/802.1Q tagging. Using the Priority Packet utility, set up the priority
filter. Then set the 802.1p/802.1Q tagging option to Enabled.
If the priority filter is set up but the setting is Disabled, the tagged packets will still
be processed by priority, if the Combo card uses a Intel 82558 or later Ethernet
controller.
There are two requirements for using IEEE 802.1p tagging effectively:
– The other devices receiving and routing 802.1p tagged packets must support
802.1p.
– The adapters must support 802.1p.
