that connect parallel IDE, SATA, SAS, and diskette drives to the system board.
Two or three types of signal cables come with the computer:
– IDE: The wider IDE signal cable has three connectors. One of these
connectors is attached to the drive, one is a spare, and the third is attached to
the primary IDE connector on the system board.
The optical drive is attached to an ATA 100 signal cable. ATA 100 signal
cables are color-coded. The blue connector is attached to the system board.
The black connector is attached to the primary IDE device. The gray (middle)
connector is attached to the secondary IDE device.
– Diskette drive (optional): The narrower signal cable has two connectors.
One is attached to the diskette drive, and the other is attached to the diskette
drive connector on the system board.
– Serial ATA: The narrower, black signal cable has two connectors. One
connector is attached to the SATA drive, and the other is attached to the
connector on the system board. SATA signal cables are connected to the
system board connectors (SATA 1 through SATA 4) in numerical order, starting
with SATA 1.
– SAS: SAS signal cables are connected to the mini-PCI Express adapter. The
signal cable has two connectors. One connector is attached to the SAS drive,
and the other is attached to the connector on the mini-PCI Express adapter.
