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).
