Problems getting 905b-tx into 100BaseT

Mon Apr 12 19:19:19 1999

Hi,

I am trying to get my 3C905B-TX into 100BaseT mode and am having little
success.  When the machine POSTS, the 100Mb/s light on my hub and machine
both are lit.  Once the kernel loads the module 3c59x, the light switches
to 10Mb/s on both.

Has anyone experienced this?  I have other 3c905b-tx's on the same hub and
they are working.  I have tried switching cards to no avail.

Any help would be appreciated.  Here is my info:

The hub is a LinkSys EtherFast 10/100 AutoSence 16 port.
