I'm building another computer, with a CD-RW (Yamaha 20X). Is there any reason that I can't just use that as the CD-ROM drive? In the past I have used this CD-Rom drive to create the 'image' that is then copied onto a CD-R, so I haven't copied 'on the fly". (I tried but it said it was configured wrong for it to do it that way, probably have to be on different IDE ribbon cables). Or should I just get a CD--ROM drive? Thanks.
