IDE Primary/Secondary Master/Slave PIO
IDE hard disk drive controllers can support up to separate hard drives.
These drives have a master/slave relationship which 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 have the ability to install up to four separate hard disks.
PIO means Programmed Input/Output. Rather than having the BIOS
issue a series of commands to effect a 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 task by themselves.
