System Overview 1-3
For systems with onboard audio, a PCI/ISA Yamaha YMF724 DS-1 AC97-
compliant advanced audio controller with 3D positioning and DirectSound 
acceleration provides audio functions compatible with a Sound Blaster Pro 
expansion card. A musical instrument digital interface (MIDI)/game port 
provides a connection for a joystick, MIDI keypad, game pad, or other 
game input device.
Most of these features are briefly described in this chapter. For a complete list 
of system features, see “Technical Specifications” found later in this chapter.
When following the procedures in this manual, assume that the locations or 
directions relative to the computer are as shown in Figure 1-1.
NOTE: Some service procedures recommend laying the mini tower computer 
on its right side to improve service access, but the descriptions in this manual 
continue to use the directions shown in Figure 1-1 for the mini tower 
computer.
