                              IDTCHK

Purpose:    Allows to detect boot viruses in certain cases.

Syntax:     IDTCHK = <ON|OFF>

By default: IDTCHK = OFF

Note:
     When IDTCHK = ON, the system tests the computer memory for key
interrupt code receivers. In case of suspicious interrupt pointers a warning
message is displayed and the user has a choice of either continuing the boot
or cancelling it.
