EIDE/PATA, SATA, and SCSI. Until recently, most motherboards included two or more EIDE/PATA host adapters for PATA devices such as hard disks, CD or DVD drives, tape backups, and removable-media drives. Most current systems now have only one EIDE/PATA host adapter, as the industry is transitioning away from EIDE/PATA to SATA inter- faces for both hard disk and DVD drives. Most recent

devices. Floppy disks and hard drives are magnetic storage devices. If exposed to a magnet data loss may result. Hard drives have a 137 GB limit. You must flash the BIOS to upgrade it and it will allow it to support a larger number of hard drive addresses. The Hard drive interfaces to attach to the motherboard are PATA/IDE, SATA, SCSI, USB, and FireWire. Along with hard drives, parallel ATA (PATA) and serial ATA (SATA) are also used for CD drives, DVD drives and tape drives. The two power supply connections

North Bridge is connected directly to the CPU. The South Bridge chip is responsible for handling the I/O functions. The SATA host adapter will let you connect an external hard drive for backup. One component that you may not see any more is the floppy drive controller. It is used to reading and writing to a computer’s floppy disk drive. By upgrading the motherboard alone will give some performance improvement to a computer system. Your I/O systems may not improve. It will depend on the adapters cards
