I am looking at building a netCF equivalent replacement board to hold a Gumstix connex motherboard.

  The NLDEV pin on the LAN91C111 schematic and on the board itself are grounded, but the datasheet for the device says it is a push/pull output.

  All three of the other gumstix ethernet boards connect NLDEV pin to pin 13 of the 92 pin connector as NIOIS16.  The netCF board grounds both the NLDEV pin and pin 13 of the connector.

  This doesn't make sense to me and want to know if anyone has an explanation for this.
