transfer data to and from your hard disk drive.
IDE DMA Transfer Access
By default, this field is enabled.
On-chip Primary PCI IDE Enabled
By default, this field is enabled.
OnChip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with
support for two IDE channels. Select
Enabled
to activate each channel
separately.
IDE Primary/Secondary Master/Slave PIO
These fields allow your system hard disk controller to work faster.
Rather than have the BIOS issue a series of commands that transfer to or
from the disk drive, PIO (Programmed Input/Output) allows the BIOS to
communicate with the controller and CPU directly.
The 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.
IDE Primary/Secondary Master/Slave UDMA
These fields allow your system to improve disk I/O throughput to
33Mb/sec with the Ultra DMA/33 feature. The options are
Auto
and
Disabled
.
PATA IDE Mode
The options for this field are
Primary
and
Secondary
. By default, this
field is set to
Primary
