I have a Compaq Presario 5600i-350, bought in 
January 99.  This uses a DEC 21143 chip for a built-in 
10baseT networking port.  However, the tulip driver does not
seem to find the right transceiver.  Here's the detail provided by the 
tulip driver when it's loaded (dmesg output):

DMESG output from insmod tulip
tulip.c:v0.91 4/14/99 becker@cesdis.gsfc.nasa.gov
eth0: Digital DS21143 Tulip rev 65 at 0x1000, 00:08:C7:13:DB:D5, IRQ 11.
eth0:  EEPROM default media type Autosense.
eth0:  Index #0 - Media AUI (#2) described by a 21142 Serial PHY (2) block.
eth0:  Index #1 - Media 10baseT (#0) described by a 21142 Serial PHY (2) block.
eth0:  Index #2 - Media 10baseT-FD (#4) described by a 21142 Serial PHY (2) block.
eth0:  Index #3 - Media MII (#11) described by a 21142 MII PHY (3) block.
eth0: ***WARNING***: No MII transceiver found!

Here are the outputs from the tulip diag program with various flags.  
I would be more than happy to run diag with different flags, etc. to
gather more info if that is necessary.
