Intel SE7500CW2 manual Super I/O, Serial Ports, Parallel Port, Floppy Port

Super I/O

The Server Board SE7500CW2 uses the Winbond W83627HF Super I/O Plug and Play Compatible with ACPI-Compliant Controller/Extender. This device provides the system with the following:

•Two serial ports

•One parallel port

•Floppy disk controller

•PS/2-compatible keyboard and mouse controller

•Two ATA 100 IDE channels

•HW monitor controller

The Server Board SE7500CW2 provides the connector interface for the floppy disk drive, dual serial ports, parallel port, PS/2 mouse, and PS/2 keyboard.

Serial Ports

The Server Board SE7500CW2 provides one DB9 connector on the back panel for serial port 1. Serial port 1 is compatible with 16550A and 16450 modes. The port can be set to one of four different COM-x ports, and each can be enabled separately. When enabled, each port can be programmed to generate edge- or level-sensitive interrupts. When disabled, serial port interrupts are available to add-in cards. An additional serial header is available on the board for an optional serial port 2.

Parallel Port

The Server Board SE7500CW2 provides a 25-pin parallel port back panel connector. The Super I/O provides an IEEE 1284–compliant 25-pin bidirectional parallel port. BIOS programming of the Super I/O registers enables the parallel port and determines the port address and interrupt. When disabled, the interrupt is available to add-in cards.

Floppy Port

The floppy disk connector on the server board provides the interface to the floppy disk drive from the floppy disk controller.

Keyboard and Mouse Connectors

The separate keyboard and mouse connectors, found on the back panel of the server board, are PS/2-compatible. The keyboard and mouse connectors are interchangeable.
