MASS STORAGE

All models include a 3.5 inch 1.44-MB diskette drive installed. A 5.2-GB EIDE hard drive is
also installed. All models include a PCI bus-mastering Enhanced IDE (EIDE) controller that
provides two EIDE interfaces supporting up to four IDE devices operating in Ultra ATA modes.
Master/slave drive selection is determined using the cable-select method, eliminating the need to
move jumpers when re-configuring drives.

SERIAL AND PARALLEL INTERFACES

This system includes two serial and one parallel port accessable at the rear of the unit chassis.
The serial and parallel ports are integrated into the I/O Controller component. The serial port is
RS-232-C/16550-compatible and operates at baud rates up to 115,200. The parallel interface is
Enhanced Parallel Port (EPP1.9) and Enhanced Capability Port (ECP) compatible and supports
bi-directional data transfers.
