I know nowadays current computers adopt EFI BIOS(as opposed to legacy BIOS) and CSM(Compatibility Support Module) support is a must-have until Win8...

My goal is to make sure my own DOS application can be executed successfully on the platform adopting (EFI BIOS and CSM) !

Thus my questions are:

(1) In EFI BIOS, is it possible to switch back to legacy BIOS via BIOS setup menu ?
Ex.  is there one setup option to do this ?

(2) Does the DOS application incorporating the DOS extender run on this environment ?
Ex. Boot the system with (EFI BIOS and CSM) to DOS mode then execute the application which is written and tested OK in DOS mode before...

Does anyone ever run the DOS application using DOS extender on this environment ?

Thanks !
