RAM Configuration
The motherboard supports up to 256 MB of DRAM. DRAM is
implemented through four 72-pin SIMM sockets.
Memory error checking and correction is supported with parity or ECC SIMMs. Parity or ECC
(EDO) SIMMs are automatically detected.

Audio Subsystem
The onboard audio subsystem is based on the Yamaha OPL family of
single-chip audio controllers (YM 715). The audio subsystem provides the digital
audio and analog mixing functions needed for recording and playing sound on personal
computers. The subsystem features:
Line and microphone level inputs
MIDI/Game port
3-D enhanced stereo
Full digital control of all mixer and volume control functions
Full duplex operation
Sound Blaster Pro, Windows Sound System, Roland MPU-401, AdLib, and Multimedia PC Level 2

How to Clear CMOS RAM
Normally, you should only have to do this procedure after you upgrade
the BIOS.
- Observe the precautions in "Before You Begin" (see page 1 of
chapter 2 of your Owner's Handbook).
- Turn off all peripheral devices connected to the computer.
- Turn off the computer and unplug the power cable.
- Remove the computer top and access covers.
On jumper block J9C1-C, move the jumper from pins 5-6 to
pins 4-5 as shown below.
- Turn on the computer and allow it to boot.
- Repeat steps 3 and 4.
- Move the jumper back to pins 5-6 to restore normal operation as shown
below.
- Replace the cover and turn on the computer.
