Supported PCI-X Quad Gigabit NIC?

  • Ok guys, looking for a supported PCI-X Quad Gigabit NIC to put in a pfSense machine. Picked up a Sun Quad GigaSwift PCI-X (501-6738-10). Read these work "great" for pfSense.

    Shutdown box, put it in & restarted it, got errors about cas:fail to probe PHYs or something close to that. Should have took a pic of the error message, before removing the card. As soon as card was pulled, machine booted back up just fine.

    Tracked down this thread:,33960.0.html

    Seems driver was missing, but was updated. I am on 2.1.5-RELEASE, so i'm not sure why that card isn't supported. LMK if there is anything I can do to get this card working.

    Other card i'm looking at is a "Intel Pro/1000 GT" meets my requirements of quad gigabit ethernet PCI-X. Should I just buy this instead?

    The Intel card will almost certainly work fine but check the forum for specific reports.  ;)
    You could try a 2.2beta image to see if that sees your Sun card any differently.


  • Looks like the PCI-X support in cas(4) was not added until FreeBSD 9.x or 10.0, though pfSense may have backported it for pfSense 2.0.x.  Check the cas(4) man page here:, and note that the 501-6738 PCI-X line is not in 8.3, but is in 10.0:

    The following add-on cards are known to work with the cas driver at this time:
         +o	 Sun GigaSwift Ethernet	1.0 MMF	(Cassini Kuheen) (part no. 501-5524)
         +o	 Sun GigaSwift Ethernet	1.0 UTP	(Cassini) (part	no. 501-5902)
         +o	 Sun GigaSwift Ethernet	UTP (GCS) (part	no. 501-6719)
         +o	 Sun Quad GigaSwift Ethernet UTP (QGE) (part no. 501-6522)
         +o	 Sun Quad GigaSwift Ethernet PCI-X (QGE-X) (part no. 501-6738)

    So, 2.2beta should theoretically work with your Sun card.  I (think I) verified the cas driver is compiled into the current 2.2beta image:
