I assume that you mean that the EEPROM settings are "force full-duplex".

vortex-diag might be convinced to write the EEPROM so that you can modify
the media settings. However, you might find it easier to just use the 3Com
DOS-based utility (if you haven't received any floppy/CD, you can download
it from www.3com.com).

Another option would be to force media setting as a module option and
disabling full-duplex this way.

The code for writting EEPROM (not specifically for this media setting) is
already there, IIRC, but it's commented out. Read the recent archives of
this list to find out why!
