Int 2F/AX=120Ah

DOS 3.0+ internal - PERFORM CRITICAL ERROR INTERRUPT

AX = 120Ah
DS = SS = DOS DS (must be using a DOS internal stack).
STACK:
WORD extended error code

Return:
AL = user response (0=ignore, 1=retry, 2=abort, 3=fail)
CF clear if retry, set otherwise
STACK unchanged

Notes: Can only be called during a DOS function call, as it uses various fields in the SDA to set up the registers for the INT 24. Reportedly sets current DPB's first root directory sector to 1
