Abstract

Described is a software implementation that provides users of Personal Computers (PCs) the ability to enable or disable an automatic "hands off" configuration operation of a PC. The implementation allows the PC to configure itself, or to be configured through configuration programs.

Automatic Auto-Configuration Enable/Disable for Personal Computers

      Described is a software implementation that provides users of
Personal Computers (PCs) the ability to enable or disable an
automatic "hands off" configuration operation of a PC.  The
implementation allows the PC to configure itself, or to be configured
through configuration programs.

      Generally, users unfamiliar with the proper configuration
procedure could become confused.  As a result, "hands-off"
auto-configuration functions are made available to the user.  When
options are added, or removed, from a PC, option settings, such as
interrupt levels, arbitration levels, Read Only Memory (ROM) address
spaces, Input/Output (I/O) address spaces, etc., will affect the
configuration status of the PC and must be correctly set by the
configuration programs.

      The concept described herein provides a way to assist a user by
enabling, or disabling the "hands-off" auto-configuration operation.
Two additional bits are added to the controlling software, as
follows:
           Bit 2 - "Hands off" auto-configuration option
                0 = not selected
                1 = selected
          Bit 1 - "Hands off" auto-configuration attempted
                0 = not attempted
                1 = attempted

      The software will set, or clear, the first bit defined, Bit 2.
Once the "hands off" feature is selected, the system will
automatically try to configure itself and will do this operation
whenever the system configuration has changed.  With the "hands off"
feature selected, the system will run the configuration programs and
will not prompt the user for input for any information type messages.

      During a boot operation, Power-On System Test (POST) will clear
the second bit defined, bit 1, and continue the POST operation.  When
the system partition boots due to a change in configuration,
COMMAND.COM will check both bits.  If the option selected bit, bit 2,
is set and option attempted, bit 1, is not set, then the "hands off"
auto-configuration is run.  Any other combination of these two bits
results in the standard auto-configuration being run.
