These white slots are PCI slots
A SiS PCI IDE controller is a peripheral card that adds additional IDE drive channels to a computer through a PCI slot. The controller is made by the company Silicon Integrated Systems (SiS).
What It Does
This is an IDE slot on a hard drive.
A SiS PCI IDE controller can be used to add more IDE channels to a computer. IDE is an antiquated type of connection that is used to connect CD-Rom drives, DVD-Rom drives, floppy disc drives and hard drives to a computer. Most computers that use IDE only support between two and four devices, because of physical and software limitations. Additionally, PCI IDE controllers can be used to add IDE connections to computers that use the SCSI connection type.
How It Connects
A SiS PCI IDE controller connects to a computer through the white-colored PCI slots on the motherboard. Most computers made before the PCI Express standard became dominant were manufactured with between two and six PCI slots.
