Code:
We need these

.text:0062B76E				 test	ah, 1
.text:0062B79D				 retn

To show the box after how many seconds you will be kicked you need to make tast ah,0
Code:
WriteAsm((void*)0x0062B76E,(PBYTE)"\xF6\xC4\x00",3); //On
WriteAsm((void*)0x0062B76E,(PBYTE)"\xF6\xC4\x01",3); //Off
To prevent that the seconds before you're getting kicked are decreasing you need to skip the retn
Code:
WriteAsm((void*)0x0062B79D,(PBYTE)"\x90",1);//On
WriteAsm((void*)0x0062B79D,(PBYTE)"\xC3",1);//Off
How to find it on netgame or other OS?

Well search for 150.0 (time after you'll see a box)
You will get flt_xxxxxxx 150.0
search the xxxxxxx and take the second one

Enjoy
