Product Description 1.7 I/O Controller The I/O controller provides the following features: • One serial port • One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP) support • Serial IRQ interface compatible with serialized IRQ support for PCI systems • PS/2-style mouse and keyboard interfaces • Interface for one 1.44 MB or 2.88 MB diskette drive • Intelligent power management, including a programmable wake-up event interface • PCI power management support The BIOS Setup program provides configuration options for the I/O controller. For information about SMSC LPC47M172 I/O controller National Semiconductor PC87372 I/O Controller Refer to http://www.smsc.com http://www.national.com/ 1.7.1 Serial Port The boards have one serial port connector located on the back panel. The serial port supports data transfers at speeds up to 115.2 kbits/sec with BIOS support. For information about The location of the serial port A connector Refer to Figure 8, page 44 1.7.2 Parallel Port The 25-pin D-Sub parallel port connector is located on the back panel. Use the BIOS Setup program to set the parallel port mode. For information about The location of the parallel port connector Setting the parallel port's mode Refer to Figure 8, page 44 Table 46, page 83 1.7.3 Diskette Drive Controller The I/O controller supports one diskette drive. Use the BIOS Setup program to configure the diskette drive interface. For information about The location of the diskette drive connector on the D865PCD board The supported diskette drive capacities and sizes Refer to Figure 11, page 51 Table 49, page 88 27
