It will associate a couple of scripts with .zimage so that when selecting open or double clicking, FindEMPEG will get the IP address of your unit and then dos ftp wiil be used to send the new kernel over. I have been using it for a while and havn't had any trouble with it.

You will of course need to have a version of Hijack installed to use the FTP server.

If your using windows 2000/NT keep an eye on the webpage I will be releasing a WinLogon extension DLL shortly that pauses/unpauses the player when you lock/unlock your workstation
