The new system im building up on a site has ha cd-rw (mitsumi 4x4x24x) and ive chosen nto to have a cd-reader since im gonna install mine (Creative 24x). The dealer will build every parts up (the cd-rw also) but I dont know about this master/slave thing. They will of course do that and test it if everything works. But when im later going to put in my cd-reader, what mode will the cd-rw be set on? And what mode should my cd-reader be set on (master or slave) ?
