Need Quick Help With Asm Code

[The Old Pirate]

mov al, byte ptr ds:[address1]
not al
mov byte ptr ds:[address1], al
cmp al, 255
je address2

How to enshorten this code? Or any other way?

cmp al, 255 ????

[Ziggy]

try

not byte ptr ds:[address1]

cmp byte ptr ds:[address1], 0FFh

je address2

Note that al is not modified at all by this code

Thanks. AL doesn't matter, the point is to make other condition for the jump in each pass.
