[cctalk] Wanted: Apple III 5MB Profile HD driver file

The title says it all - the Apple III has an external hard drive called the Profile, but a driver has to be installed on the boot floppy - it won’t boot from the HD. There were also 10MB Profiles, with a different driver file I’m guessing.  I have the driver file for the 10MB, but it doesn't seem to work with my 5MB drive. Please help if you can. Thanks- Steve.
