IDE HDD Block Mode
IDE Block Mode allows the controller to access blocks of sectors rather than a
single sector at a time. The default is Enabled.
Options: Enabled, Disabled.
IDE DMA transfer access
Automatic data transfer between system memory and IDE device with minimum CPU
intervention. This improves data throughput and frees CPU to perform other tasks.
Options: Enabled, Disabled.
On-Chip Primary (Secondary) PCI IDE
The mainboard supports two channel of ordinary IDE interface. Select “Enabled”
to activate each channel separately.
If you do not use the onboard IDE connector, set the Onboard Primary
(Secondary) PCI IDE to “Disabled”.
IDE Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode (0-4)
for each of the four IDE devices that the onboard IDE interface supports. Modes 0
to 4 provide successively increased performance. In Auto mode, the system
automatically determines the best mode for each device.
Options: Auto, Mode 0 ~ 4.
