| IDE Technology | The hard drive controller is permanently attached to the hard drive and controls where data is physically stored on the drive without interference from system BIOS or OS |
| SCSI | Another type of hard drive technology that uses a SCSI bus that can be connected to other SCSI devices |
| PC Boot OS | Stored on a secondary storage device, called "bottable device": Floppy disks, CD-ROM, and removeable drives |
| CMOS Setup | Boot priority is determined by the order that the system BIOS uses to attempt to boot from a bootable scondary storage device. |
| SCSI Hard Drive | Cannot be the bootable device unless this feature is supportded by the system BIOS |
| External Removable Drives | Are Iomega Zip drives, Iomega Jaz drives, Imation SuperDisk, tape backup drives, writeable CD-ROM drives (CD-R), and rewriteable CD-ROM drives (CD-RW) |
| Imation SuperDisk | Can use a floppy disk or a 120 MB disk |
| ATAPI | Have to do with the interface protocol between the device and the CPU, which must be supported by the OS |
