I don't know where you got the drivers from, but you can try these sites :
Big book of amiga hardware: a4066.dms or this one:
Installers heaven: a4066.dmsHope these drivers work for you guys.
EDIT: Without trying to be a smart-ass: these files are
DMS-archives. you have to unarchive them to a floppy disk.
Just to make sure you know ...
