Is your cable an 80-wire one ?
There are different versions of the VT82C586A, with the same revision (0x06).
Guessing if it's Ultra/33, or 66 capable from the driver isn't that easy
and seem to be wrong in some cases.
But I wasn't aware of a Ultra/100 capable version. Do you know the name
of the motherboard's chipset ?
