I'm moving onto my next project of getting my Umax S900 running. My first goal is changing everything from SCSI to IDE as the devices since I got plenty of IDE stuff. Now my question is I have an IDE controler card "Promise Ultra100 TX2". Will this card work with Macs? If not, where is a cheaper card located at that I can purchase. I am willing to buy used but thats for the other forum. Also if I were to have a card, would I still need to use Mac optical drives and certified hard drives or will anything work. Dumb question but I'm new to the scene.
