If it works without changing anything, then yes. That is, if both your SATA and your IDE and any optical drives show as listed, then just adjust the BIOS to choose boot order. If one or more drives don't show in the list, then make sure that each IDE device is either Master or Slave per cable.
If you have a single IDE on each cable, then set the Hard Drive by itself to Master or Master w/o Slave. Set the IDE CD/DVD to Master on its own cable.
There's usually a tiny chart on the drive showing jumper settings to set Master, Slave or Master w/o Slave if avail. Otherwise, you have to check it out on the mfg website.
(If you look at my config, you can see I've set a few IDE drives in my life!!)
