Device-Driver Types
Device drivers fall into two general categories:
application-specific and device-specific.
Application programs load application-specific device drivers into memory.
These device
drivers stay in memory while the application is running, and generally are cleared from
memory when you exit from the application.
Device-specific drivers are loaded into memory each time you turn on the computer.
Some
device drivers check for the presence of a device each time you turn on the computer.
If
the device it supports is not attached or is not turned on, the device driver is not loaded
and might generate an error message.
After they are loaded, device-specific drivers stay in
memory.
For more information about loading device drivers, refer to your
operating-system documentation and the documentation that comes with your hardware or
device drivers.
Video Device Drivers
Video device drivers are provided on the
IBM Software Selections CD
that comes with your
computer.
If your computer has IBM-preinstalled software, video device drivers are already
installed on the hard disk of your computer.
(However, note that DOS video device drivers
might need to be installed.)
Advanced Power Management
Conserving energy is important for your computer and is also environmentally friendly.
For both of these reasons, your computer provides energy-saving software, collectively
called Advanced Power Management (APM).
The following are the APM features included with your computer:
±
APM BIOS
is important if your computer uses an operating system that supports
APM-capable computers.
When this setting is disabled, all APM BIOS support is
disabled.
±
Automatic Hardware Power Management
allows you to reduce or suspend power to
components of the computer after a preset time of inactivity is reached (a SCSI hard
disk drive is unaffected by this feature).
For more information on setting and using this
feature, see the
PC 300GL User Guide
.
±
Activity Monitor
allows you to select which devices are monitored to determine if the
system should enter or exit the low power state.
Not all operating systems support this.
