Abstract

Disclosed is a system configuration process providing the user of a system with the ability to enable or disable a bypass feature allowing the system to boot the operating system without user intervention, despite the presence of all but the most severe errors, as detected by Power-ON Self Test (POST) On an IBM PS/2* System without this feature, when POST detects an error, the user must acknowledge the error before the operating system is booted by POST.

Bypassing Acknowledgement of Post Error

      Disclosed is a system configuration process providing the user
of a system with the ability to enable or disable a bypass feature
allowing the system to boot the operating system without user
intervention, despite the presence of all but the most severe errors,
as detected by Power-ON Self Test (POST) On an IBM PS/2* System
without this feature, when POST detects an error, the user must
acknowledge the error before the operating system is booted by POST.

This requirement for human intervention leads to unnecessary
down-time for unattended network server systems.

      This bypass feature is enabled or disabled from the "Change
Configuration" screen of the configuration program running from the
PS/2 Reference Diskette, on which either "Bypass System Programs on
Error....  ffl Disabled" or "Bypass System Programs on
Error....ffl Enabled" is displayed.  The user can switch between the
"Disabled" and "Enabled" choices using the F5 and F6 function keys.
Each time the user causes the selection to change, the configuration
software determines the new selection, updating a location with
nonvolatile storage to contain the new selection.

      Each time the system restarts, the POST test routines run.  If
POST detects an error, it checks the status previously chosen by the
configuration programs to determine the action to be taken.  If the
nonvolatile storage loses its battery backup power, or if this
storage otherwise b...
