Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields set the PIO mode
(0-4) for each of the four IDE devices that the onboard IDE interface
supports. Modes 0 through 4 provide successively increased
performance. In Auto mode, the system automatically determines the
best mode for each device. Set this function to one of the configuration
options:
Auto, Mode 0, Mode 1, Mode 2, Mode 3 or Mode 4.
Primary/Secondary Master/Slave UDMA
Ultra DMA/33 implementation is possible only if the IDE hard drive
supports it and the operating environment includes a DMA driver
(Windows 95 OSR2 or a third-party IDE bus master driver). If the hard
drive and the system software both support Ultra DMA/33 and Ultra
DMA/66, select Auto to enable BIOS support. Set this function to one of
the configuration options:
Auto or Disabled .
Primary/Secondary Master/Slave RAID
Configure the RAID controllers accordingly. The setting for this option is
Enabled or Disabled .
IDE Prefetch Mode
The onboard IDE drive interfaces support IDE prefetching, for faster
drive accesses. If a primary and or secondary add-in IDE interfaces are
installed, set this field to
Disabled if the interface does not support
prefetching. Set this function to one of the configuration options:
Enabled or Disabled .
IDE DMA Transfer Access
This setting is for the standard controllers on the motherboard,
configuring it accordingly. Set this function to one of the configuration
options:
Enabled or Disabled .
IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple
sector read/write. If the IDE hard drive supports block mode (most new
drives do), select Enabled for automatic detection of the optimal number
of block read/writes per sector the drive can support. Set this function to
one of the configuration options:
Enabled or Disabled .
SATA Controller
This item determines if the SATA Controller is functional, configuring it
accordingly. Set this function to one of the configuration options:
Enabled or Disabled.
SATA DMA Transfer
This item selects the DMA mode for devices connected through SATA
channels. Set this function to one of the configuration options:
Enabled
or Disabled.
SATA Primary/Secondary Master RAID
These items set the SATA Primary and Secondary Master RAID
devices. Set this function to one of the configuration options:
Enabled or
Disabled
