Dear All...

Im compared the patched one with origin one and found that they are diffrent with codes below... Can guys explain for me what mean are in these codes?

088D: 0800 or [bx+si], al
088F: 75EC jne 087D
0891: F9 stc
0892: 0A49B3 or cl, [bx+di-4D]
0895: EC in al, dx
0896: 5E pop si
0897: 0400 add al, 00
0899: 305F15 xor [bx+15], bl
089C: 54 push sp

it is trash

Very unusual to see an IN command unless it's a kernel driver, but then it's 16 bit code. Also, the rest of the code looks very odd. Are you sure you're disassembling in the right mode?. If so, I would suspect that this section is data, not code. Can you post disassembly of both normal and patched code, and a bit more of each above and below what you have posted above, say 0860 to 08C0.

It is data, could be encryption keys, serial seeds, or anything.
