Internal PCI/IDE
This chipset contains an internal PCI IDE interface which supports
two IDE channels. The settings are Primary, Secondary, Both, or Disabled.

IDE hard drive controllers can support up to two separate hard drives.
These drives have a master/slave relationship which are 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 to
ability to install up to four separate had disks.
PIO means Programmed Input/Output. Rather than have 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 complete task by themselves. This is simpler and more
efficient (and faster).
Your system supports five modes, numbered from 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select the
best available mode. This is true for the next four setup items:
1. IDE Primary Master PIO
2. IDE Primary Slave PIO
3. IDE Secondary Master PIO
4. IDE Secondary Slave PIO
Ultra DMA 33
IDE hard drive controllers can support Ultra DMA 33 Hard Drive. If you use
Ultra DMA hard drive, then you will get a better performance. The settings
are Auto, Enabled, and Disabled.
1. Primary Master UltraDMA
2. Primary Slave UltraDMA
3. Secondary Master UltraDMA
4. Secondary Slave UltraDMa
