AM-6060 Computer Owner's Manual, Rev. 00
Appendix C - Super I/O
Super I/O is designed to significantly increase character output for all serial ports using the AM318.IDV
driver. This includes the AM-6060's four on-board serial ports. Super I/O handles character output in a
much more efficient manner than any other previously released AMOS serial port driver, which reduces
the load on the CPU and makes more CPU cycles available for other tasks.
In earlier versions of AMOS, Super I/O was a separate, optional feature. In all versions of AMOS
supported on the AM-6060, Super I/O is included in the operating system.
DISABLING SUPER I/O
In most situations, you will always want to have Super I/O enabled. However, if you have an application
program that does not run properly on a Super I/O enabled serial port, you can disable Super I/O. You
can't disable Super I/O on an individual serial port; if you disable it, it is disabled for all four ports.
To disable Super I/O, use the following procedure:
1. Create a copy of your system initialization command file as described in Chapter 5.
2. Use AlphaVUE to modify your TEST.INI file. Locate the first TRMDEF statement. Disable
Super I/O by adding
/O
(that's an "O", not a zero) to the statement. For example, change:
TRMDEF TERM0,AM318=0:19200,AM65,100,100,100
to
TRMDEF TERM0,AM318/O=0:19200,AM65,100,100,100
3. Save the file and leave AlphaVUE. The use the MONTST command to boot with the test
initialization file, as described in Chapter 5.
If you want to be able to run with Super I/O either on or off, keep the test initialization file under a
different name than your standard initialization file. You can then boot under either initialization file,
depending on the Super I/O state you want.
