Your PC’s Performance Features
Making the Most of Your PC’s IDE Channels
Making the Most of Your PC’s IDE Channels
Your PC integrates an advanced IDE controller for connecting internal
mass storage devices. This controller can manage the operation of up
to four IDE devices and supports both hard disk and CD-ROM drives.
Your PC’s IDE Channels
Your PC's integrated PCI IDE controller provides two Fast IDE
channels for connecting IDE mass storage devices. Each channel can
be used for connecting up to two IDE devices. Both IDE channels
support the highest data transfer rates currently available and offer
optimized performance with any combination of IDE devices.
PIO and DMA Modes
The PCI IDE controller uses two different techniques to transfer data
with IDE devices: Programmed Input/Output (PIO) modes and Direct
Memory Access (DMA) modes. When transferring data to or from an
IDE device, the IDE controller will automatically select the technique
that is most suited to the transfer.
