Well, this is my first tut I give out to everybody.. I only made some small ones for friends around :)

Ok, so this crackme wants me to insert the correct cd... hmm...
So, start the crackme and pass the nag so you get in that screen where you can press "re-test CD"
Now we need a good breakpoint in SoftIce to break on .. since I don't really wanna use W32dasm 
I just try some out and start with a simple one like GetDriveTypeA.
So, goto softice and type "bpx GetDriveTypeA"  and exit again.
Now press on "Re-Test CD" and plop, your in SoftIce ! let the fun begin :)
So, now you see this: (I copy'd this out of the Disassembled file and removed much you won't see in 
SoftIce)

:004010AF 6A00                    push 00000000                now still stay at the JNE and type:

Ok, so we know where the good msg is and where the bad msg is, now let's take a look again at the JNE.
:0040109E 7525                    jne 004010C5
As we could allready gues it will jump to 
:004010C5 6800100000              push 00001000
and this is the start of the bad msg ! 
Now press F10 again in SoftIce so you take the jump.. or not.
As you see you take it, now go back and do it over again.
When your on the JNE type in SoftIce type: "d eip=004010A0"
This command will jump to 004010A0.. same if the cd is insert.
Now press X to let it roll and you will see the good msg on your screen !
So now all we have to do is changing 
:0040109E 7525                    jne 004010C5 
          9090         
90 stands for NOP = No Operation. So now the jne ain't even there ! so it will always goto the good msg :)
