Re: Slow booting with Intel EtherExpress Pro 100B

Back to back problems occured for me when I made my own cable and 
made the mistake of mixing the twisted pairs for receive and transmit.
Some of the packets made it and some did not.  Very wierd.  I made a
another cable and was sure to keep the receive and transmit 
pairs separate and had no more trouble with lost packets.
