The option description:
Sets behavior of the computer at detection of those or other errors during initial testing. If value [No Errors] operating system loading will be possible even in case of detection of an error by procedure POST, if [All Errors] loading is possible only at total absence of errors is installed. Value [All, But Keyboard] allows to ignore errors (or absence) keypads, [All, But Diskette] — errors (or absence) the disk drive, [All, But Disk/Key] — errors (absence) as keypads, and the disk drive. In most cases the loading stop is optimal at any error ([All Errors]).
The exception is made by servers and the computers fulfilling a role of those. As a rule, they work without the monitor, the keypad and the mouse, is frequent at them there is no disk drive. To avoid the error report of procedure POST and, as consequence, loading stops, select value [All, But Keyboard] or [All, But Disk/Key].
