Hrmm, I guess I should phrase the question this way:

I have installed a Fibre Channel card into a new FreeBSD 8.x box.  I have both isp(4) and mpt(4) are loaded and the device still doesn't appear in /dev.  pciconf shows:

none2 at pci0:8:1:0: class=0x0c0400 card=0x656c1242 chip=0x15601242 rev=0xb2 hdr=0x00
 vendor   = 'Jaycor Networks Inc'
 device   = 'Dual Channel 2 Gb/s Fibre Channel-PCI-X (JNIC-1560)'
 class    = serial bus
 subclass = Fibre Channel

So I'm guessing that this device is unsupported.  So, what I was trying to ascertain from my original question is: does anyone have any FreeBSD experience with a Fibre Channel card that they like under FreeBSD that I can replace this one with?

Basically I'm asking for a recommendation along the lines of "I have card X and it works beautifully".  :)
