Yes. There is a less graceful way to handles these, documented in the
following CDB article:
http://www.suse.de/Support/sdb_e/maddin_cdchanger.html
quoting:
"It is not that simple with ATAPI changes. There is only one device file
(e.g. /dev/hdc). You need to switch the CDs manually with a little tool.
You need to unmount the CD, change it and remount it afterwards.
This tiny tool is called cdload. Go and get the package which may be
obtained from our FTP site under
ftp://ftp.suse.com/pub/suse_update/special/cdload.tgz . Unpack it and
install cdload to /usr/bin and invoke it as follows:
cdload /dev/hdc 3
This should load the 4th CD.
It is not that comfortable as with SCSI changes."
As the file is getting rather old, (1998), you may want to rebuild it for
your system like so:
mkdir tmp
cd tmp
tar xvzf cdload.tgz
gcc cdload.c -o cdload
su
cp cdload /usr/bin
chmod go-w /usr/bin/cdload
chmod a+xr /usr/bin/cdload
