I don't know if there is a way to manage more than 2 IDE channels. (Problems with free interrupts, DMA channels, OS will not find it,...) And I don't think that a ISA port is able to manage concurrent interrupts. Therefor you need a PCI controller. If you need such many peripherals use a SCSI controller and a SCSI ZIP. If you want only to connect a ZIP connect it via the parallel port.

I have a computer that has 2 cd-roms and 2 hard drives. &nbsp;I was wanting to add a ZIP drive so I purchased an ISA IDE controller. &nbsp;I set the jumpers for it to be a PRIMARY controller and inserted into a slot. &nbsp;It isn't detected. &nbsp;Is this what i should be doing and what could be causing it to not be detected??

Adding 2nd IDE controller.
