I hooked everything up, put my hard drive on IDE channel 1 on the Promise controller and left my DVD-ROM on the onboard IDE secondary master channel. When I start up it will detect my DVD-ROM and then go into the Ultra 100 bios and detect my hard drive. Then the screen changes again and I get the error, "system disk invalid, please insert another disk." I think my system is trying to boot from the DVD-ROM, but how can I fix this? I'm thinking I might have to move my DVD-ROM to the Promise IDE channel 2 and have nothing onboard, but this would be inconvient, and I'd rather keep it on the motherboard... even then it STILL might not work. Any ideas, suggestions?
