There seem to be numerous CD rom drives on sale that are sold with
SCSI adaptors much cheaper than the adaptors supported by BSD (Adaptec
etc).  What is the difference between these adaptors and the supported
ones?  Obviously they may require different drivers, but are the
adaptors themselves inherently less capable?  One dealer told me that
some adaptors are only suitable for "multi-media" and others only work
with "disks smaller than 700Mb".  He couldn't explain why this was.
Is he right?  And if so why - do the controllers not support the full
SCSI protocol?

ancient India, Babylon and Egypt, as well as of Greece and Rome, and at this
day it is still resorted to by cunning and malignant savages in Australia, 
Africa and Scotland."  - J G Frazer, The Golden Bough
