Dick: Not all PCI cards work in Macs. Drive controllers, like Video cards, must have Mac compatible ROMS on board. >Looks like the SYBA card will go back to Fry's and I refuse to pay $80 for a >Mac card that looks just like the PC card. The Syba cards are not Mac compatible. Their web site says so: "Q: What kind of OS does it support? A: Our controller card only support Windows 98SE/ME/2000/XP and Linux OS" > Anybody been able to get a PC PCI Serial ATA controller card to >work on a Mac? Yes. I've been using the FirmTek 1S2 for about 2 years now. It works great. Other Mac compatibles come from Acard, Sonnet and SIIG. As with all these products, you'll pay a premium for being a Mac user, but it pays off in the long run. SATA drives are cheaper than parallel IDE drives, specially at higher capacities. Back when I bought my Firmtek card ($45 special from OWC), the cost of the controller + 200 GB SATA drive was only $20 more than the cost of an IDE drive alone. Sean
