I/O Features

Built-in I/O
The EZ-Flex system contains built-in input/output
controllers to save both money and system setup time. The
controllers can be configured by the AMI EISA BIOS
Setup. The controllers include:
• two serial ports, which are software-configurable for
COM 1, COM2, COM3, or COM4, or can be disabled by
the EISA Configuration Utility (ECU). Additional serial
ports can be configured using adapter cards in
expansion slots. The interrupts can also be configured by
the ECU. The serial port connectors are 10-pin dual-
inline bergs.
• a parallel printer port, software configurable to LPT1 or
LPT2, or disabled by the ECU. Interrupts are configured
by the ECU. The parallel port connector is a 26-pin dual-
inline berg connector.
• a floppy drive controller that supports up to two low or
high density and 3½ or 5¼ inch drives. An Intel 82077AA
diskette controller and standard 34-pin floppy connectors
are provided.
• Mouse support. The IBM® PS/2-type mouse is
supported. A five-pin berg is provided to attach to a
standard AT-type mouse cable. A five-pin to six-pin
miniDIN adapter is needed to attach the PS/2 mouse.
• AT® and PS/2®-compatible keyboards are supported. A
five-pin DIN plug for AT-compatible keyboards and a
five-pin berg for PS/2-compatible keyboards are
provided.
