SoftICE Versions

Hi,

Please tell me which is the latest version of SoftICE, that
I should download for application debugging on WinXP.

After reading almost all of the threads containing "SoftICE"
I'm still confused. I dont know which is the latest version
and which files to download.

What is the difference between Compuware DevPartner
and Compuware DriverSuite and NuMega SoftICE?

If DriverSuite is for only for driver development, why is everyone
in the forums recommends downloading DriverSuite 3.0?

And finally if I should download SoftICE DriverSuite 3.0, do
I have to download Compuware Driver Studio 3 Beta also?

Thanks for your time.
