i have a 4100 dell dimension-i know -oldie,but goody.so far i've been happy with it, but missing out on the latest technology,i.e. dvd burning.this dell has only two 5.25"bays which are occupied with dvd-rom(nec5700a) and dvd-rw (pioneera06).both are set to cable select as per dell original config.i do want to hook up my lite-on cd-rw to this system-bought pci usb2.0 card and external 5.25"enclosure for cd-rw.do i set it for cable select or what?thanks.
