System Board 4-11
PCI/IDE Port
The system board supports high-performance primary and secondary PCI/IDE
ports on the system board. The primary PCI/IDE port has an enhanced IDE
interface that supports a PIO Mode 4 device with 16 MB per second 32-bit wide
data transfers on the high-performance PCI local bus. The port supports Ultra
DMA/33.
The installed hard drive is connected to the primary PCI/IDE port connector
with a signal and power interface cable. The installed CD-ROM drive is
connected to the secondary PCI/IDE port connector with a signal and power
interface cable.
Parallel Interface
The system has a 25-pin bidirectional parallel port on the system board. Port
specifications conform to the IBM-PC standards. The port supports Enhanced
Capabilities Port (ECP) and Enhanced Parallel Port (EPP) modes for devices
that require ECP or EPP protocols. The protocols allow high-speed bi-
directional transfer over a parallel port and increase parallel port functionality
by supporting more devices.
The BIOS has automatic ISA printer port sensing that works with most devices.
If the BIOS detects an ISA printer port mapped to the same address, the built-in
printer port is disabled. (Verify in the BIOS Setup that printer ports mapped to
the same address are enabled or disabled appropriately.) The BIOS also sets the
first parallel interface port it finds as LPT1 and the second port it finds as LPT2.
The interrupt is set at IRQ7 via the BIOS Setup utility. Software-selectable base
addresses are 228h, 378h, and 278h.
Sets of I/O addresses for the parallel port are given in the following table (see
Section 2, “System Configuration,” for interrupt levels). This is a list of all
possible configurations. The parallel port uses only one set.

Parallel interface signals are output through the system board’s 25-pin,
D-subconnector. The connector is located at the back of the system unit.
