How do I know which Gigabit driver to install on my Mac

Small Tree Intel based gigabit cards can either be:

Intel 8254X chip based
or
Intel i350 chip based

In our gigabit downloads area we provide both drivers but how do know
which driver to use?

On your Mac under "About This Mac"->"More Info"->"System Report"->PCI Cards"
you will find the ethernet ports, click on one and below you will see the hardware
information which includes:

Vendor ID: 0x8086
Device ID: 0xYYYY
Subsystem Vendor ID: 0x8086
Subsystem ID: 0x000a

Where 0xYYYY above identifies whether to use the driver
for the i350 chip or the 8254X chip.

Device IDs for the i350 chip are:
0x1521
0x1522
0x1533

If you see other Device IDs then you should use the other
driver.
