SCSI Emulation is in two parts--first a message to the kernel to
tell it to assume emulation is done Second is a modprobe of
scsi and a link to the appropriate SCSI device
The first part is simple in /etc/lilo.conf or in drakboot
(Control Center Boot Config) make sure you have this in the
append
hdc=ide-scsi
if for example it is hdc.
Now in /dev you need to do the following
cd /dev && rm cdrom2 && ln -s scd0 cdrom2
if, for example, the /etc/fstab entry uses /dev/cdrom2 for your
CDRW.
Finally somewhere you need a
modprobe ide-scsi
It can be dropped int the next to last line of /etc/rc.local
(an extra one won't hurt if your system is already doing one)
It is a little known fact that ordinaty plain vanilla CDROMs can
also be scsi-emulated in the same manner. Our tests over the
past 5 months show this works just as well as the dual structure
we now support.
