For OS 3.0/3.1 you need atapi.device. It does not come with
3.1 You need IDEFIX97, but it is a demo and a requestor
will pop up! Get OS3.9, it patches the scsi.device
to use ATAPI devices and CD-ROMs work great with scsi.device,
no atapi.device needed anymore. BUT to install 3.9 you
need a CD-ROM drive! So again use IDEFIX97 to setup the
CD-ROM and install the new OS... It is worth it.
