I currently have a iWill branded HPT370 based IDE raid PCI controller for 3x WD160 GB IDE hddz, I want to add a Promise SATA Fastrack TX2300. I want it to use with my eSata enclosure, which is currently connected only via the slower USB2. I'm wondering if i plug in the new Promise controller will my PC get TWO add-on BIOS prompts or will the PROMISE take over from the iWill PCI ATA RAID card? I figure i might be able to turn them on/off via the system BIOS?
