controller. Well, you could make do with two disks on a single
controller, but performance would be terrible.
Next question: Will it hurt anything to put the CDROM drive as the Slave on the secondary controller? This is a no-no in the SCSI world, since I think it slows the entire bus down to the speed of the slowest device. But I need a CDROM to actually install Fedora, and I'd rather not buy an additional controller....
Statement 1 is correctThanks for the help!

It's no problem to have a CD-ROM as slave together with a harddrive on the same controller. It will not slow down the whole controller.
Statement 2 is not. With IDE busses, all devices on the bus operate at the speed of the slowest device. Thus if you put an ATA133 drive on a bus with an ATA33 cdrom, the entire bus only operates at ATA33. They are improving this, and AFAICT the new SATA controllers do not have this limitation.
