Intel® Core™2 Quad Processors - The ultimate multi-core performance

Introducing Intel® Core™2 Quad processor for notebook and desktop PCs, designed to handle massive compute and visualization workloads enabled by powerful multi-core technology. Optimized for the longest possible battery life without compromise to performance, Intel Core 2 Quad processors for notebooks allow you to stay unwired longer while running the most compute-intensive applications.

Providing all the bandwidth you need for next-generation highly-threaded applications, the latest four-core Intel Core 2 Quad processors are built on 45nm Intel® Core™ microarchitecture enabling faster, cooler, and quieter mobile and desktop PC and workstation experiences.

Plus, with optional Intel® vPro™ technology, you have the ability to remotely isolate, diagnose, and repair infected desktop and mobile workstations wirelessly and outside of the firewall, even if the PC is off, or the OS is unresponsive.

Features and Benefits

With four processing cores, up to 12MB of shared L2 cache,¹ and up to 1066 MHz Front Side Bus for notebooks, and up to 12MB of L2 cache² and up to 1333 MHz Front Side Bus for desktops, the Intel Core 2 Quad processor delivers amazing performance and power efficiency enabled by the all new hafnium-based circuitry of 45nm Intel Core microarchitecture.

Whether you're encoding, rendering, editing, or streaming HD multimedia in the office or on the go, power your most demanding applications with notebooks and desktops based on the Intel Core 2 Quad processor.

Plus, with these processors you get great Intel® technologies built in:

Windows Packet Capture (WinPcap)

WinPcap is the Windows version of the libpcap library; it includes a driver to support capturing packets.

Wireshark uses this library to capture live network data on Windows.

General information about the WinPcap project can be found at the WinPcap web site.

The libpcap/WinPcap file format description can be found at: Development/LibpcapFileFormat

WinPcap Versions

We strongly recommend that you use version 3.1 or 4.0. Some annoying bugs are fixed in these versions!

See the "Add or Remove Programs" list of the "Control Panel" for the installed version.

Latest Stable Release: 4.0.2

The current WinPcap release version is 4.0.2. The 4.0.x versions contain the following improvements:

• Support for Windows Vista and XP 64 bit added
• Allows remote capture to work with Wireshark
• Based on libpcap 0.9.5

WinPcap 4.0 does not support Windows 3.1, 95, 98, or ME.

Previous Stable Release: 3.1

This version contains substantial bug fixes and extensions above the 3.0 release:

• based on libpcap 0.9.3, with many fixes and extensions above the older version
• dial-up connections (e.g. PPP) can be captured on Windows 2000, Windows XP, and Windows Server 2003, as well as Windows 95, Windows 98, and Windows Me, which were supported by previous releases
• "can't get a list of interfaces" error fixed

See the change log for WinPcap for a more complete list (although some of those bugs might be bugs in older 3.1 betas rather than in 3.0).

Installation

The Wireshark installer will copy the WinPcap installer and call it, so you get installation done "all in one place". This is the same WinPcap installer that you can get from WinPcap's download page.

However, you might need to install WinPcap by the standalone installer, if you want to try the latest alpha/beta, or there might even be a new WinPcap release version available.

The User's Guide Installing Wireshark under Windows page will also describe how to install WinPcap.

Windows Versions

You'll find complete information about this topic at WinPcap FAQ #14.

Vista (aka Longhorn)

Works except for capturing on PPP/WAN interfaces. See: WinPcap FAQ #28.

XP 64 bit

Works except for capturing on PPP/WAN interfaces. See: WinPcap FAQ #14.

Laurent Rabret mentioned (if it's not working with WinPcap): "There's a workaround. You should be able to use the "netcap" application (on the support tools of the Windows XP CD-ROM http://support.microsoft.com/?id=310875 ) With netcap, it's possible to record network traffic in a file Wireshark can handle. Therefore, it's a 2 steps process but it's better than nothing!"
