Be careful using on-board controllers.

The Intel card would be an INTEL Pro1000MF,
right? This would be quite
expensive (~ EUR 430), but good performance and
stability would warrant
that.
ATM, we are using the onboard controller
(Broadcom BCM5704C wired to the
pci-x bus). I did not have opportunity to do
performance measurements,
but we do have problems with our Linkpro
1000SX/1000TX converters, the
3rd of which has already died.
That's why i want to give a PCI-X card with
fiber interface a try.
No, that would be the 1000MT, the MF is a fiber
card I believe. They are about US$120. in the US.
Our building has fiber cabling, that's why i am looking for a fiber
card. The 1000SX/1000TX converters that we use are just to unreliable.
How do you know its wired to the PCI-X bus, since
I don't believe that the controller has a way of
reporting the way that the intel controller does?
What MB do you have?
It is a Tyan Thunder K8SD Pro S2882-D
http://www.tyan.com/products/html/thunderk8sdpro_spec.html
The spec says that the BCM5704C is connected to PCI-X Bridge A
(64Bit,100MHz).
Also keep in mind that the bge driver is a piece
of crap; driver quality is a much more telling
factor in these free OS's than the card in many
cases. The EM and FXP are the only drivers worth
anything (mainly because neither were written by
mass-driver mill man Bill Paul).
That really sounds bad. I wonder if others can confirm that.
