1-6 Technical Information
Serial devices through two buffered 16C550 UART serial ports, supporting
up to 115.2 KB per second (COM 2 may be disabled by default)
Two USB devices
Speaker and microphone connectors (line in, line out, microphone in).
Table 1-2 lists the major chips on the system board. See Appendix A, “Connector Pin
Assignments,” for a list of the system board connectors. See Appendix B, “Jumper
Settings,” for a description of board jumpers.
NOTE:
The processor is mounted on a CPU
card with an attaching heatsink that installs as a
replaceable unit (CPU module) in Slot 1 on the
system board.
