I normally have my superdrive card in slot 5. If I attach a couple of 3.5"
UniDisks onto the two superdrive they're mapped to slot 2. A third
UniDisk isn't recognized.

I used to use the four drives for installing system 6.0.1 before I burned
a bootable installer CD.  The only problem I've seen is the same infernal
blinking of the disk access light as when you have a 3.5" UniDisk hooked
up to the smartport.

I believe System 5.0.4 was currant when the card came out. Anyways,
your suspicions are correct in that the problem lay with the 3.5" UniDisk
Driver. 5.0.4 keeps saying UniDisk 3.5 requires a driver even though the
driver was already on the 5.0.4 boot disk. Replacing the driver with the
one from System 6.0.1 seems to allow use of the 3.5" UniDisk drive
