3-12 Reviewing System Features
NOTE
In the desktop model, one Ultra DMA/33
device is supported on each IDE channel. If an
additional IDE device is added to an IDE channel,
neither device can use Ultra DMA/33 mode due to
the length of cable required.
USB Ports
The Universal Serial Bus (USB) ports allow you to add new
serial devices without opening up the system — simply plug
them into the ports. The USB determines system resources
for each peripheral and assigns them without user
intervention. Up to 127 devices can be daisy chained to a
single USB port.
Sound System
The Yamaha sound system installed on the system board in
multimedia models provides compatibility with Sound
Blaster Pro™, Sound Blaster™ 2.0, Ad Lib™, MPU-401,
and Microsoft® Windows Sound System™ for PC sound
applications.
For detailed sound specifications, see the “System
Specifications” in Appendix B.
Plug and Play Support
Your computer comes with a Plug and Play BIOS which
supports Plug and Play technology. Plug and Play
eliminates complicated setup procedures for installing Plug
and Play expansion boards.
