IDE ports

The system board comes with a fast IDE port (primary channel) and a
standard IDE port (secondary channel). Each port supports up to two
IDE devices for a total of four IDE devices.
The fast IDE port has an enhanced IDE interface which supports up
to 10 MB per second 32-bit wide data transfers on the high-
performance PCI local bus. Standard IDE supports 2 MB to 3 MB
per second on the ISA bus.
The standard hard disk drive is connected to the fast IDE port
(primary channel) as the master device. A second IDE device can be
connected to the fast IDE port as a slave device.
The standard CD-ROM reader is connected to the secondary IDE
port as the master device. A second IDE device can be connected to
the secondary port as a slave device.

I/O ports and connectors

The input/output (I/O) ports and connectors are controlled by a
National Semiconductor PC87307 Super I/O Controller on the
system board. The controller is an ISA Plug and Play compatible
multifunction I/O device.
The I/O ports and connectors on the system board include an
enhanced parallel port, one buffered high-speed serial port, two USB
ports, and keyboard and mouse connectors.
