Do you have the boot slot set to the one containing your hard drive controller card? What type of controller are you using? If it's a RAMFast you need to hold down Open-Apple-0 when you boot. This will let you set the boot partitions. Also, if you are using an Apple SCSI card, did you install the SCSI drivers? LJSilicon http://members.aol.com/ljsilicon/plain.html
