What motherboard are you using? If you are using an 80-pin UDMA cable in IDE 1, you should set the HDD to 'CS' and plug it in at the top end of the cable. Slave drive uses the middle (drive also set to 'CS'). CS stands for cable select and the position of the drive on the cable determines the master/slave status.

Really depends on what peripherals you are using - CD/DVD drives, etc.

As for the ZIP, is it connecting to the PCI card using a parallel port or USB? If parallel, you should check your BIOS and see if the onboard parallel port is enabled and if it has been assigned an IRQ address. What brand/model of card is it? You could have a conflict.

Also - in your BIOS, did you enable 'Plug and Play OS'?
