DelKey=<key>
Causes the CONFIG.SYS command with the specified key to be remarked out in the CONFIG.SYS file.
For example, the INF file item
DelKey=Break
would cause a Break=on command to be remarked out in the CONFIG.SYS file.
The DelKey item has the same effect as the RemKey item. There can be multiple DelKey and/or RemKey items in a section of the INF file.
