This function determines whether a USB keyboard or USB mouse 
can be used with software or tools on an MS-DOS platform (e.g. 
SIMATIC PC/PG Image Partition Creator). The ISA bus is disabled 
when this option is set. The USB Boot function must be enabled to 
allow booting from a USB device, or if the system is to be operated 
without USB support with a USB keyboard or USB mouse.  
The USB Legacy Keyboard/Mouse function also needs to be 
enabled in addition to USB Boot (Enable), if operating systems 
without USB support are operated with a USB keyboard or mouse. 
The "Post errors" function must be disabled in the Main menu -> 
Boot options of the BIOS setup to enable operation only with USB 
keyboard and USB mouse and automatic system startup.
