Monitor support
The video subsystem provides a 15-pin monitor connector on the system board. For information on
connector pin assignments, see Appendix A, “Connector pin assignments” on page 25.
Video memory
The video memory interface is controlled by an integrated graphics subsystem on the AGP adapter with
up to 16 MB video RAM for 2D/3D graphics.
Audio subsystem
The PC 300PL Personal Computer comes with an integrated audio controller. These models are capable
of playing and recording sounds and support SoundBlaster, Adlib, and Microsoft Windows Sound System
applications.
The device drivers for the preinstalled audio adapter are on the hard disk. The device drivers are also
available on the
Product Recovery CD
or
Device Driver and IBM Enhanced Diagnostics CD
that comes
with the computer.
If you connect an optional device to the audio adapter, follow the instructions provided by the
manufacturer. (Note that device drivers might be required. If necessary, contact the manufacturer for
information on these device drivers.)
The following connectors are available on the integrated audio controller:
Line/headphone out
port for connecting powered speakers. To hear audio from the adapter you must
connect a set of speakers to the Line out port. These speakers must be powered with a built-in
amplifier. In general, any powered speakers designed for use with personal computers can be used
with the audio subsystem. These speakers are available with a wide range of features and power
outputs.
Line in
port for connecting musical devices, such as a portable CD player or stereo system.
