I run win 98se as my guest and always disconnect the rtc as soon as I start up. I haven't noticed any odd effects. What "media operations" will be endangered, and how? Or is deleting the rtc different from just disconnecting it? I run a laptop; running 100% CPU really isn't ok with me--the machine gets noticably hot over time and battery life is impacted. -- "Brian, the man from babble-on" bts@babbleon.org Brian T.
