386 I think
As I remember 0F is a prefix for >=80286 instruction....
ex:
SMSW DX (0F 01 E2) 80286 +
MOV EDX, CR0 (0F 20 C2) 80386 +
XADD DX, DX (0F C1 D2) 80486 +
and 0F BE :
0f be c9 movsx ecx,cl
0f be c0 movsx eax,al
MOVSX reg16,r/m8 ; o16 0F BE /r [386]
MOVSX reg32,r/m8 ; o32 0F BE /r [386]
see it IDA !
