Software Configuration
3-3
Note
If the Configuration Memory is ever configured to a state that
makes it impossible to regain control of the system, a shorting
block can be installed temporarily on J2-7/8 to defeat the
Configuration Memory and use defaults that are in the ROM-
BIOS. One can then use the "hot-key" (CTL-ALT-DEL) to
activate SETUP and reprogram the Configuration Memory.
The shorting block on J2-7/8 must be removed for the
Configuration Memory to have an effect.
The configuration options controlled by SETUP are given in Table 3-1. Examples of how a typical
system can be configured for many of these options are given later in this chapter.

Table 3-1. Software-controlled Configuration Options
The SETUP function is contained directly within the ROM-BIOS. This allows access to all
configuration parameters by using the "CTL-ALT-ESC" key sequence at powerup or reset time. As
a convenience, a SETUP utility, executable from the DOS command line, provides entry into the
ROM-BIOS SETUP function at any time during system operation. The SETUP utility also allows
you to save Configuration Memory contents to a disk file. The disk file can be used later to set the
Configuration Memory in the same system or another CoreModule/PC system. Refer to Appendix A
for a detailed list of the system parameters controlled by SETUP and how to use the program.
