Descriptions of error information, for errors arising from system software problems, will be provided in this
section.
Up to eight sets of information, related to the system software’s errors, will be stored in the SRAM.
By executing hi_sysdwn( ) the line number (on which the error occurred), the error code and detailed information
of the error, will be stored in the error log. r
Hi_sysdwn( ) will be executed in the following two circumstances:
1. hi_sysdwn( ) will be intentionally stored if fatal errors occur with each BIOS.
2. If multiple exceptions, fatal exceptions, illegal command codes and trap command errors occur.
2. Error Log's Entry Function
Up to twenty-four sets of information, related to errors starting with the latest error, will be displayed by the
