Does anyone know the difference between the 3c905B revisions? I have just got 8 of the cards, And two of them are marked; ASSY 03-0172-400 REV-A on the label side, and the main chip is; 3Com 40-0483-001 9821S <some number> LUCENT 40-04831 and the others are 03-0172-410 C 3Com 40-0483-004 9851S <some number> LUCENT 40-04834. Anyone know of any issues with these cards, or the changes made in revision? -- Simon
