network card config info

Hi managers

How can I probe my system to see what make and model of network card 
I have in my DS20 AlphaServer?  I've tried things like sysman and 
hwmgr but although they show me lots of information about how my 
network is configured, I can't seem to get the basic hardware 
information out (with disks it's easy hwmgr - view devices and I can 
see manufacturer and model etc, but getting similar for the network 
card is non-obvious).

Thanks
Derek
