Intel Vig390s manual Parallel Port, Floppy Controller, PS/2 Keyboard and Mouse Interface

Parallel Port

The connector for the multimode bi-directional parallel port is a 25-pin D-Sub connector located on the back panel. In the Setup program, the parallel port can be configured for the following:

•Compatible (standard mode).

•Bi-directional (PS/2 compatible).

•Extended Parallel Port (EPP).

•Enhanced Capabilities Port (ECP).

Floppy Controller

The I/O controller is software compatible with the N82077 floppy drive controllers and supports both PC-AT and PS/2 modes. In the Setup program, the floppy interface can be configured for the following floppy drive capacities and sizes:

•360 KB, 5.25-inch

•1.2 MB, 5.25-inch

•720 KB, 3.5-inch

•1.2 MB, 3.5-inch (driver required)

•1.25/1.44 MB, 3.5-inch (default configuration)

•2.88 MB, 3.5-inch

PS/2 Keyboard and Mouse Interface

PS/2 keyboard and mouse connectors are located on the back panel. The +5 V lines to these connectors are protected with a PolySwitch circuit that, like a self-healing fuse, re-establishes the connection after an over-current condition is removed.

The keyboard controller contains the AMI Megakey keyboard and mouse controller code, provides the keyboard and mouse control functions, and supports password protection for power on/reset. A power on/reset password can be specified in Setup. The keyboard controller also supports the hot-key sequence <Ctrl><Alt><Del> for a software reset. This key sequence resets the computer’s software by jumping to the beginning of the BIOS code and running the Power-On Self Test (POST).
