Support for SCSI hard-disk drives and CD-ROM drives when a SCSI controller card is installed in an expansion-card slot.

A high-speed, high-resolution PCI video controller card installed in an expansion-card slot, rather than an integrated video controller, to provide video flexibility for customers.

A 16-bit integrated audio controller that provides sound functions com- patible with a Sound Blaster Pro expansion card.

A MIDI/game port for connecting a MIDI device, joystick, game pad, or other game input device.

An integrated high-performance serial port and a bidirectional parallel port.

Two USB connectors, which can simplify connecting peripheral devices.
