This page consists of two main fields: CD writer and CD-ROM. Both fields look identical, however, in the upper part of the page you can configure which CD writer should be used by KreateCD and in the lower part of the page you can select which CD-ROM player should be used by KreateCD for a direct copy.
To select a CD writer or CD-ROM, click on the (active) radio button in front of your choice. If the options is inactive (grey), than the text No drive connected should be right next to it. If you have multiple SCSI hosts in your computer, you can switch between them by using the spinbox labeled SCSI host.
