Not if it's an old 3Com 3C509. They don't negotiate. I have a few of
those I use with an unmanaged switch. I was planning on someday seeing
if just forcing them to full duplex would work (hoping the switch was
smart enough to recognize the need: decent SMC with auto wire adjust ,
etc., so I'm hopeful). I "programmed" the eproms, but the Linux drivers,
in their infinate wisdom, force them back to half duplex. *sigh*.
