* FUNCTION: VOID cmdGetKbdLayout( VOID )
*
* Input Client (DX) = 0 - Keyb.com not installed
* 1 - Keyb.com installed
* Client (DS:SI) = pointer where exe name has to be placed
* Client (DS:CX) = pointer where command options are placed
*
* Output
* Success (DX = 1 )
* Client (DS:SI) = Keyb.com execuatable string
* Client (DS:CX) = command options
*
* Failure (DX = 0)
*
* COMMENTS: This function check KEYBOARD ID for Win session
* and if ID != US then return lines with
* filename and options to COMMAND.COM
*
* If bPifFastPaste is FALSE, then we always run kb16
* for all keyboard ID including US, to give us a more
* bios compatible Int 9 handler. 10-Jun-1993 Jonle
