Hi, 

I added code to recognize 3com 1000base-SX card as miibus module and 
compiled them, but I do not have time to test yet.
I think this may solove my original problem that link of SUN SX card
does not go up, though 3com card goes up well.

I will start testing it from Jan.4,2004.  I uploaded the fixed code
on my web page, http://members.aol.com/hyama99/.

I appreciate If someone gives me comments on the code before testing.

Regards,

Hideki Yamamoto
