Hello Mr Becker, I wanted the user's manual for the i82557. I did search the intel site and came up with a few docs on the i82557, but not the user's manual. If I am not mistaken, that is what has the specs on the CSR/BCR registers. Could you kindly point me to where I can find it. I apologize if I should'nt be mailing in this id in the first place. Thanks in advance, Sanjay.H
