Don't know exactly what you mean with "porting osst.c over generic ATAPI code",
but osst is SCSI by design - a SCSI version of the drive exists.
Making osst ATAPI
is therefore not appropriate. If osst works with libata as earlier suggested,
then that would be the best solution.
Unfortunately, my IDE test drive died, OnStream went out of business some time
ago, so I can't get a new one, hence I (osst maintainer) can't test this :-(
