3.9 Onboard PCI-IDE
The PCI-IDE controller is a part of the 82440LX PCIset. It supports PIO
mode 3/4 and bus mastering Ultra DMA/33. The peak transfer rate of
PIO mode 3/4 can be as high as 17MB/sec. Using HDDs that support
Ultra DMA/33, the peak transfer rate can reach 33MB/sec. There are two
IDE connectors - primary IDE and secondary IDE. With two devices per
connector, up to four IDE devices can be supported.
3.10 DMA Channels
There are seven DMA channels available on the motherboard. Only
DMA2 is used by the floppy controller. In the case that ECP mode on the
parallel port is utilized, DMA1 or DMA3 will be used.
3.11 I/O Port Address Map
Each peripheral device in the system is assigned a set of I/O port
addresses which also becomes the identity of the device. There is a total
