What kinad of card do i have c/w numbers

I’ve got an old school ISA full length card with the rj45 box that screws on to the back of the digiboard once installed.

The DBI A/N = 30000604 Rev D and the S/N is 03408407

I have made numerous attempts to access the http://www.digiboard.com/support/index.jsp (support) page but i guess it doesn’t work on weekend (JRun Servlet Error)

Anyhow i’m tryin to find a RedHat 6.2 driver for it.
