In earlier BIOS versions, the boot device boot sequence had only a few simple items such as C, A, CD-ROM, and now there are more than these in the BIOS, and it adds a lot of startup items. So, do you know what devices these startup items refer to?  


Soft disk drive, referred to as FDD, which is what we usually call the floppy drive.  


Needless to say, we all know that this is a CD-ROM drive, that is, we usually speak of optical drive.  


The full name of the SCSI is: Small Computer system Interface, a "small computer system-specific interface", as the name suggests, a scalable interface designed for small computers that allows computers to install other peripherals to improve system performance or add new functionality, This is generally referred to as a SCSI hard drive or optical drive.  

Zip and LS120

Zip and LS120 is a large-capacity disk, developed on the basis of the original 1.44MB disk. Their development goal is to replace the existing 3.5-inch disk, but not popular.  

Zip is a large-capacity disk drive developed by American Iomega, which replaces the traditional floppy drive for archival transfer and sharing of data. However, the Zip drive is not compatible with traditional 1.44MB floppy disks, so six companies such as 3M, COMPAQ, Panasonic, Mitsubishi and Hitachi introduced a LS-120 floppy disk drive with 120MB compatible 1.44MB floppy disks in 1996.  

These two devices are rarely used domestically, and with the advent of flash drives, their capacity and speed advantages have all gone.
