You have two LAN interfaces. One is a Marvell PCI Express gigabit lan
controller. The other LAN consists of two pieces of hardware. The
Southbridge has a MAC layer for a LAN, while a separate Marvell PHY
chip drives the Ethernet transformers for that interface. The Southbridge
interface could have features such as the Nvidia firewall etc.
I would try the Marvell PCI Express controller. The PDF copy of the
manual I have here, does not correctly identify which LAN connector
is which. You could try changing the LAN port, and see if things
improve.
In any case, the Audigy2 would sit on the PCI bus, and electrically
if the card fried the bus, both LANs should continue to run. So as
GT points out, there must be something else out of sorts, such as
resource allocation.
Things you could try:
1) Clear CMOS, then set up BIOS settings again. Before you do that,
record any custom settings you've been using. Clearing the CMOS
usually requires unplugging the computer first. Check the manual
for additional instructions (section 2.6 "Clear RTC RAM").
2) You could also just take a look through the BIOS, and make sure
the LAN controllers are still enabled.
With a tool like Everest, you can verify whether peripherals like the
PCI Express Gigabit LAN are seen on the bus or not. Under the Devices
tab, PCI Devices.
