You don't need to do anything with HD toolbox. If the
CD-ROM is ATAPI the 3.1 operating system installation
steps should bring up an OS that can get to the point
of allowing you to open up a CD and clicking on
Install.
If it is an IDE/ATAPI based CD-Rom then you just
need to ensure that the wide connector with all the wires
in it is pushed in the back and that the power connector
is installed properly. You might want to check to see if
the master/slave dip switches are set correctly.
