[ale] moving CD-ROM from master to slave

[James P. Kinney III]

Make sure you moved/added the jumper on the cdrom drive that specifies
that it is now the slave device. Some systems will try and run even
though there's a conflict, others won't boot at all.

Easy process:

unplug the new hard drive and the cdrom. boot to single user mode. Edit
the /etc/fstab file and comment out the line that has the cdrom.
Shutdown and reconnect the drives making sure they have the jumpers that
make the hard drive master and cdrom slave. reboot to single user mode.
try mounting a CD to verify that the  cd is now hdd "mount -t iso9660
/dev/hdd /mnt/cdrom". Then try and fdisk on /dev/hdc. If both are OK,
uncomment the fstab line and change it to be /dev/hdd. 

Some system make a symlink from the /dev/hdx device to /dev/cdrom. Be
sure to check and move it as needed. The /dev/cdrom is what is used to
detect CD insertion for automounting.
