INT 21 - DOS 3.1+ - SET EXTENDED ERROR INFORMATION
        AX = 5D0Ah
        DS:DX -> 11-word DOS parameter list (see AX=5D00h)
Return: nothing.  next call to AH=59h will return values from fields AX,BX,CX,
          DX,DI, and ES in corresponding registers
Notes:  documented for DOS 5+, but undocumented in earlier versions
        the MS-DOS Programmer's Reference incorrectly states that this call was
          introduced in DOS 4, and fails to mention that the ERROR structure
          passed to this function is a DOS parameter list.
BUG:    DR-DOS 3.41 and 5.0 read the value for ES from the DS field of the DPL;
          fortunately, MS-DOS ignores the DS field, allowing a generic routine
          which sets both DS and ES fields to the same value
