    My memory is faulty at the moment, but if the Intel card runs on the IGB kernel module it's software. It must use the e1000e or e1000 module to be hardware.
    The Intel Server and Desktop PCI-Express Adapters Product Selection Guide is helpful.

    The Intel EXPI9301CT(BLK) 10/100/1000Mbps PCI-Express Gigabit CT Desktop Adapter uses the Intel 82574L chipset which uses the e1000e driver.

    The Intel E1G42ET(BLK) 10/100/1000Mbps PCI-Express Dual and Quad Port Server Adapters both use the Intel 82576 chipset which uses the igb driver.

    The Intel EXPI9400PT(BLK) 10/100/1000Mbps PCI-Express Gigabit Copper Connection for Servers uses the Intel 82572GI chipset which uses the e1000e driver.

    The Intel EXPI9402PT(BLK) 10/100/1000Mbps PCI-Express PRO/1000 PT Dual and Quad Port Server Adapters both use the Intel 82571GB chipset which uses the e1000e driver.

    There are three Linux Base Drivers for Intel Gigabit Network Connections:

    1. e1000.x.x.x.tar.gz support all Intel® PCI and PCI-X gigabit network adapters/connections.

    2. e1000e-x.x.x.x.tar.gz driver supports the Intel PRO/1000 PCI-E (82563/6/7, 82571/2/3/4/7/8, or 82583) based gigabit network adapters.

    3. igb-x.x.x.tar.gz supports Intel® 82575/6 & 82580-based gigabit network connections.

    Note that the CT has more advanced features than the PT, but the ET is fancier yet.

    So now, ahem, which of these are hardware driven and which are software driven? You're telling me the most fancy of the bunch, the ET, is software driven? And that's a bad thing?

    The IGB module is a software driver with a firmware... but as I said before I haven't seen the negative performance penalties with the "software" interface from Intel. For all intents and purposes you may as well consider it hardware.

    yeah, disgusting. I might just keep the CT's strictly for workstation installs, especially considering the comments about them further up in this thread

    Here you go http://www.newegg.com/product/produc...82e16833106121

    Too bad it's PCI instead of PCI-E. Guess I'll stick with my batch of CT's. This product code resolves correctly to the GT, according to Intel's docs.
