Operating System Compatibility
Intel® Priority Packet III can be installed in Windows* 2000 or Windows* XP.

Intel Priority Packet II can be installed in Windows NT* 4.0, Windows* Me or Windows* 98.

Intel Priority Packet (original version) can be installed in Windows NT 4.0, Windows Me or Windows 98.

Hardware Compatibility

• Minimum Host Computer System Requirements
  Priority Packet doesn't require additional features to work on your computer. You can use Priority Packet on computers that meet the minimum system requirements for the host operating system, as long as they contain a supported network interface.
  
  
• Network Interface
  Priority Packet I (original version) will only work on Intel 10/100 adapters, not 1000 MB capable adapters. Priority Packet II and Priority Packet III can be used on 10/100 network interfaces based on the Intel® 82558, 82559, 82550 and 82551 LAN controller chips, and on the PRO/1000 families of server and desktop adapters. This includes the following adapters:
  • PRO/1000 Family of Desktop Adapters
    
  • PRO/1000 Family of Server Adapters
    
  • PRO/100 M Desktop Adapter
    
  • PRO/100 S Desktop Adapter
    
  • PRO/100 S Server Adapter
    
  • PRO/100 S Management Adapter
    
  • PRO/100+ Adapter
    
  • PRO/100+ Server Adapter
    
  • PRO/100+ Management Adapter
    
  • PRO/100+ Dual Port Server Adapter
    
  • PRO/100 VE Desktop Adapter
    
  • PRO/100 VM Desktop Adapter
    
  • PRO/100 SR Mobile Adapter
    
  • PRO/100 SR Combo Mobile Adapter
    
  • PRO/100 CardBus II
    
  • PRO/100 RealPortTM CardBus II
    
  • PRO/100 LAN+Modem56 CardBus II
    
  • PRO/100 LAN+Modem56 RealPort™ Cardbus II
  
  Many motherboards with built-in LAN interfaces also use the 82558, 82559, 82550, 82551 and the 8254x family of LAN controllers.

  Note: The first generation Intel® PRO/1000 Gigabit Server Adapter (PWLA8490) does not support QoS frame tagging

• Priority Queue
  The Intel® Priority Queue feature works independent of 802.1p tagging. It does not alter the structure or content of the packets, and therefore can be used on any Ethernet or Fast Ethernet hub, switch, bridge or router if 802.1p tagging is not enabled on the adapter. This feature is only available on the 10/100 adapters, not the PRO/1000 adapters.
  
  
• 802.1p/802.1q Tagging
  802.1p/802.1q tagging alters the packet structure from the standard type 2 Ethernet frame by adding an additional 4 bytes of data to the packet. Internetworking hardware (hubs, switches, bridges, and routers) that is not compliant to the IEEE 802.1p standard won't interpret the altered packet structure and is not compatible with 802.1p/802.1q tagging.
  
  When using the 802.1p tagging feature, 802.1p compliant hardware should not be mixed with non-compliant hardware on the same segment. 802.1p compliant hardware should be configured to strip the additional bytes of data from the packets before forwarding them to any segments that contain non-compliant hardware or end nodes (i.e. workstation or server NICS).
