FreeBSD 5.1 on ASUS P4C800 (onboard NIC problems, 3Com 3C940)

[Gab]

Hello,

I successfully installed FreeBSD 5.1 on my ASUS P4C800 motherboard. The
only remaining problem is that sysinstall did not find any ethernet
device during the installation. The onboard NIC is a 3Com 3C940.

What should I exactly do in order to make the system detect this 3Com
3C940 ethernet device and make it work properly?

Many thanks for your help.
