I'm running Windows 98 under Parallels Desktop 3.0 for Mac build 4560. This is not for masochistic reasons; I have an app that refuses to run under XP (probably due to the "improved" file security model). It runs fine, really. Well, as "fine" as Win 98 ever gets, with the hangs and the random crashes, but the app runs and responsiveness is...ok. However, the CPU pegs at 100% as soon as Win 98 starts to boot, and stays there until the VM is halted. If anyone else is running Win 98, please tell us: is this what you see? Does Win 98 just peg the CPU as a matter of course? I'm willing to believe that this is how this ancient OS actually does business, but I'd like to know there's nothing actually wrong here.
