The following are two short routines to do a warm or a coldboot.
Hope they help you out.


COLDBOOT:
70A2:0100 BA4000        MOV	DX,0040                            
70A2:0103 8EDA          MOV	DS,DX                              
70A2:0105 BB7200        MOV	BX,0072                            
70A2:0108 C7070000      MOV	WORD PTR [BX],0000                 
70A2:010C EA0000FFFF    JMP	FFFF:0000                          

WARMBOOT:
70A2:0100 BA4000        MOV	DX,0040                            
70A2:0103 8EDA          MOV	DS,DX                              
70A2:0105 BB7200        MOV	BX,0072                            
70A2:0108 C7073412      MOV	WORD PTR [BX],1234                 
70A2:010C EA0000FFFF    JMP	FFFF:0000
