In the early BIOS release, only this simple number of C, A, CD-ROM, etc. in the boot device, and now there are more than these items in the BIOS, and it has added a number of startup items. So, do you know which devices are these startup items?
FLOPPY
Soft disk drive, referred to as FDD, is the floppy drive we usually say.
CD-ROM
Don't say more, everyone knows that this is a disc drive, that is, we usually speak CD-ROM.
SCSI
The full name of SCSI is: Small Computer System Interface, translation is "Small Computer System Special Interface"; as the name suggests, this is for a small computer design expansion interface, which allows computer to install other peripherals to improve system performance or increase new The function, which generally refers to the hard disk or optical drive of the SCSI.
ZIP and LS120
ZIP and LS120 are a large-capacity disk, which is developed on the basis of the original 1.44MB disk. Their development goals are replacing the current 3.5-inch disk, but it is not popular.
ZIP is a large-capacity disk drive developed by Iomega, using it to replace the archive transfer and sharing of traditional floppy drive data. However, ZIP drivers cannot be compatible with traditional 1.44MB floppy disks, so six six companies such as 3M, Compaq, Panasonic, Mitsubishi and Hiti have introduced a capacity of 120MB compatible with a 1.44MB floppy disk drive in 1996.
Both devices are rarely adopted in China, and with the birth of the flash drive, their capacity and speed advantages have waters.
HDD-0, HDD-1, HDD-2, HDD-3
These four refers are hard drives, but why do you have four? Everyone knows that the motherboard has two IDE interfaces. Each interface can be taken from two IDE devices, a total of 4. If you pick up 4 hard drives, the hard disk of the first IDE interface of the first IDE interface is HDD-0. The hard disk from the disk position is HDD-1; the second IDE interface is the hard disk is HDD- 2, the hard disk from the disk position is HDD-3. If the first starter device is set to HDD-0, the system will first boot from the first hard disk, that is, the first IDE interface of the primary disc position; the first start device is set to HDD-1, it will Start boot from the second hard disk, that is, the hard disk of the slave disk position of the first IDE interface; the following are pushed.
It should be noted that if you only have a hard drive in your computer, no matter which IDE interface, no matter whether the primary disk is still slave, as long as the first starter device is HDD-0, the system will start from the hard disk. start up.
USB-FDD, USB-ZIP, USB-CDROM, USB-HDD
These are some USB interface devices, USB-FDD is the floppy drive of the USB interface; USB-ZIP is the ZIP drive of the USB interface; USB-CDROM is the drive of the USB interface; USB-HDD is the hard disk of the USB interface (this usually also Support flash drive started).
Lan
Network equipment, such as NIC.
Now, everyone understands.
