IDE HDD Block Mode
This field allows your hard disk controller to use the fast block mode to
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 .
