The four IDE PIO (programmed Input/Output) fields let you set a PIO mode
(0-4) for each IDE device that the internal PCI IDE interface supports. Modes
0 through 4 provide successively increased performance. In Auto mode, the
system automatically determines the best mode for each device.

These fields allow you to set the Ultra DMA in use. When Auto is selected, the
BIOS will select the best available option after checking your hard drive or
CD-ROM.

Block mode is also called block transfer, multiple commands, or multiple
sectors read/write.
