IDE. The options are: Enabled, Disabled.
IDE Prefetch Mode
When set at Enabled, it allows data to be posted to and prefetched from the
primary IDE data ports. Data prefetching is initiated when a data port read
occurs. The read prefetch eliments latency to the IDE data ports and allows
them to be performed back to back for the highest possible PIO data trans-
fer rates. The first data port read of a sector is called the demand read.
Subsequent data port reads from the sector are called prefetch reads. The
demand read and all prefetch reads must be of the same size (16 or 32 bits).
The options are: Enabled, Disabled.
Primary Master/Slave PIO
Allows an automatic or a manual configuration of the PCI primary IDE
hard drive (master/slave) mode.

hard drive (master/slave) mode.
The options are: Auto, Mode 0, Mode 1, Mode 2, Mode 3, Mode 4.
Primary Master/Slave UDMA
Allows an automatic configuration of the PCI primary IDE hard drive
(master/slave) mode if Ultra DMA is supported both on the motherboard
and the hard disk. The options are: Auto, Disabled.
