There's an extra cutout on cards that fit in the 64/66 slots. For eg,
the 4 port DLINK ether cards I tried to put into the tyan 2466 wont go
in the 64/66 slots because the cutout on the card is missing and so the
notch has nowhere to go in the card: card doesnt fit. The intel eepro cards
that also go into this system DO fit in those slots because they do have
the keyed cutout. (The Tekram SCSI cards also wont go in those slots for
eg). I would assume that this keyed cutout is to help differentiate between
cards that can do 3.3v and those that cant.
