I installed OpenBSD 4.6 on an Intel SR1630HGP server that has an Intel
S3420GPLC board. There are three network interfaces on the server: one
card, and two on the motherboard.

The card is recognized:

em0 at pci1 dev 0 function 0 "Intel PRO/1000 MT (82574L)" rev 0x00: apic
8 int 16
 (irq 11), address 00:1b:21:49:8d:8c

As is one of the interfaces on the board:

em1 at pci3 dev 0 function 0 "Intel PRO/1000 MT (82574L)" rev 0x00: apic
8 int 16
 (irq 10), address 00:15:17:ad:e4:20

Looking at dmesg, the devices flanking pci3 are:

ppb1 at pci0 dev 28 function 0 vendor "Intel", unknown product 0x3b42
rev 0x05: a
pic 8 int 16 (irq 10)
pci2 at ppb1 bus 2
ppb2 at pci0 dev 28 function 4 vendor "Intel", unknown product 0x3b4a
rev 0x05
pci3 at ppb2 bus 3
em1 at pci3 dev 0 function 0 "Intel PRO/1000 MT (82574L)" rev 0x00: apic
8 int 16
 (irq 10), address 00:15:17:ad:e4:20
ppb3 at pci0 dev 28 function 6 vendor "Intel", unknown product 0x3b4e
rev 0x05
pci4 at ppb3 bus 4
vga1 at pci4 dev 0 function 0 "Matrox MGA G200e (ServerEngines)" rev 0x02

I would expect there to be an "em2" for the second onboard interface,
but there is none. `ifconfig -a` doesn't show any additional interfaces.

Any magic hacks I can try to get that second onboard interface working?

Thanks,
Ross
