Install the WinMEDDK.exe (including all debugging tools). 

Run the dbginst.exe (which will be in the folder DEBUGKIT, which should be in C:\DEBUGKIT folder) utility to install the DDK debugger. This copies files that allow the debugger to be started. 
***************
*DO NOT REBOOT* when prompted to by the utility. 
***************
                            ***************
Install Softice in Windows directory (not default Numega folder...normally will install in C:\Program Files\numega etc) OR  copy your winice.dat, winice.exe, and siwvid.386 from the softice directory to your windows directory. . Once again *DO NOT REBOOT* 
                            *************** 

Copy the suplied debugger.exe to the windir (this will overwrite the debugger.exe that was installed previously)

Reboot. 

To abort SoftICE loads, or if you have a problem loading windows, do a step-by-step boot (press F8 (Ctrl on some computers) when starting computer and select step by step), and select "NO" when it prompted to load debugger.exe. 



NOTE FROM SOMEONE:

Before you install wme_ddk you should copy your old IO.SYS from the root (C:\) to another directory. In the future you can replace the new one in case you want to reboot without softice or vice-versa.
