4.7 Integrated Peripherals
The IDE hard drive controllers can support up to two separate hard
drives. These drives have a master/slave relationship that is
determined by the cabling configuration used to attach them to the
controller. Your system supports two IDE controllers--a primary
and a secondary--so you can install up to four separate hard disks.
PIO means Programmed Input/Output. Rather than having the
BIOS issue a series of commands to affect the transfer to or from
the disk drive, PIO allows the BIOS to tell the controller what it
wants and then let the controller and the CPU perform the
complete task by themselves. This is much simpler and more
efficient (also faster).
