APPENDIX C
SUPER I/O
Only AMOS 2.2C users can take advantage of Super I/O. AMOS 1.X operating systems
do not support Super I/O.
Super I/O, which requires a PIC (Product Installation Code), is designed to significantly
increase character output for all serial ports using the AM318.IDV driver. This includes
all AM-318 board serial I/O ports, as well as the AM137’s eight on-board serial ports.
The more terminals you have on your system performing character output, the more you
will benefit from Super I/O.
Super I/O handles character output in a much more efficient manner than any other
previously released AMOS serial port driver, which greatly reduces the load on the CPU
and makes more CPU cycles available for other tasks.
C.0.1Enabling Super I/O
Earlier in this document, you downloaded the software required to support Super I/0.
The instructions in this section describe how to enable Super I/O.
Once you enter the product installation code (PIC), the product overlay file is forever
modified and will not accept a new PIC. This can be a problem if you happen to enter an
incorrect PIC. As a safeguard, make a copy of the Super I/O overlay file before you do
the SSD encodement. Type:
COPY SER000.SAV=SER000.OVR
RETURN
By saving an unmodified version of the overlay file, you will be able re-enter the PIC if
necessary.
To perform the SSD encodement, enter the following commands:
LOG SYS:
RETURN
SERPIC
RETURN
You will be prompted for a Product Installation Code (PIC).
