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.
On-chip Primary PCI IDE Enabled
This field, by default, 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.
