SoftICE v4.05 or higher supports Windows Millennium. Follow these steps to install SoftICE on Millennium:

1. Download the 'Microsoft Debugging tools for Windows Millennium' available at http://www.microsoft.com/ddk/debugging/. You need the debug version of io.sys out of this debugging kit in order to run SoftICE on Millennium. So, find the file winboot.sys in the directory where the tools were installed. Rename it io.sys, and copy it into your root directory (C:\). We strongly recommend that you back up the old version of io.sys.

2. If you are running SoftICE 4.05, copy the following files into your Windows directory:
winice.exe
siwvid.386
winice.dat
Also copy debugger.exe available at http://www.numega.com/drivercentral/utilfiles/debugger.exe into the Windows directory.
