[NTLUG:Discuss] SCSI compatability driver

[falconjetflyer@netscape.net]

The CD-Writing Howto say that I need a SCSI compatability driver so linux sees my IDE cd writer as a scsi device.  One other things it says the following creates device file entries under /dev.
I presume that I am to run it as a script?

test `whoami` = 'root' || echo "You must be root to execute the commands."
cd /dev/
umask -S u=rwx,g=rwx,o-rwx
[ -f loop0 ] \
    || ./MAKEDEV loop \
    || for i in 0 1 2 3 4 5 6 7; do mknod loop$i b 7 $i; done
[ -f sg0 -o -f sga ] \
    || ./MAKEDEV sg \
    || for i in 0 1 2 3 4 5 6 7; do mknod sg$i  c 21 $i; done

Listing: creating of devicefiles 

Is that true?

Then should I also run this script?  

test `whoami` = 'root' || echo "You must be root to execute the commands."
cdrecord -scanbus > /dev/null
if ! (pidof kerneld || test -f "/proc/sys/kernel/modprobe"); then
    echo "Neither kerneld nor kmod are running to automatically load modules".
fi
report_no_autoload() {
    echo "Ensure the module $1 is loaded automatically next time."
}
if test ! -f "/proc/scsi/scsi"; then
    report_no_autoload scsi_mod  && insmod scsi_mod
fi
if ! grep "^........ sg_" /proc/ksyms > /dev/null; then
    report_no_autoload sg  && insmod sg
fi
if ! grep "^........ sr_" /proc/ksyms > /dev/null; then
    report_no_autoload sr_mod  && insmod sr_mod
fi
if ! grep "^........ loop_" /proc/ksyms > /dev/null; then
    report_no_autoload loop  && insmod loop
fi
if ! grep iso9660 /proc/filesystems > /dev/null; then
    report_no_autoload iso9660  && insmod iso9660
fi
echo "The following is only needed for IDE/ATAPI CD-writers."
if ! grep ide-scsi /proc/ide/drivers > /dev/null; then
    report_no_autoload ide-scsi  && insmod ide-scsi
fi
cdrecord -scanbus

If the info is inadequate let me know  and I will include.
