1. This sounds like the IDE cable is the wrong type.
2. The floppy, just unplug it, and worry later, who uses floppy drives these days anyway?
3. If a USB keyboard, the system may well not detect it till all up and running, and it wont go that far. IF USB, i would diable 'halt on keyboard error' in the bois.
The main hurdle, the IDE one, make sure that the cable is the right way round both ends, and the right type (80 conductor).
The red tracer on the cable should go to pin one on the mobo, and pin 1 on the drive, and the drive should be set via it's jumpers correctly, but how may depend on the drive. Options are parked (rarely found), master (MA) or cable select (CS).
