Peripheral Controller
The advanced integrated peripheral controller supports two serial ports, two universal
serial bus ports, one parallel port, diskette drive, PS/2-compatible keyboard and mouse,
and integrated Real Time Clock (RTC). The system provides the connector interface for
each port.
Serial Ports
Both serial ports are relocatable. Each serial port can be set to one of four different
COM ports and can be enabled separately. When disabled, serial port interrupts are
available to add-in boards.
Parallel Port
One IEEE 1284-compatible 25-pin bidirectional EPP (supporting levels 1.7 and 1.9)
parallel port is provided. BIOS programming enables the parallel port and determines
the port address and interrupt. ECP mode is supported with 2 possible DMA channels.
When disabled, the interrupt is available to add-in boards.
