Understanding System Features 3-7
USB Ports
The two Universal Serial Bus (USB) ports allow you to add
serial devices without opening up the system; simply plug
them into the port.
„
The ports are hot-pluggable: You can plug in a peripheral
without shutting down the computer; the USB determines
system resources for each peripheral and assigns them
automatically.
„
If you attach an external USB hub, up to 127 devices can
be connected to a single PC.
Dual IDE Channels
The system board provides two independent bus-mastering
PCI IDE interfaces. They support such ATAPI devices as a
CD-ROM drive and Ultra DMA/33 hard drives. Up to four
IDE devices may be connected at a time.
Power-Saving Feature
An Advanced Power Management (APM) feature in the
BIOS can put the system into a power reduction mode of
operation. This feature reduces energy consumption, but still
allows the system to respond to requests from external
devices, such as modems or a network.
In Setup, you can adjust how long a period of inactivity will
elapse before the energy-saving Standby mode takes effect.
This is a convenient way to save power when you need to be
away from your computer for a short period of time.
Press a key or move the mouse and your system quickly
returns to full power and to where you left off.
