That's probably the problem. For some reason, certainly on my Dell, disabling SpeedStep throttles the CPU down to 1.2GHz on bootup, from its full 2.0GHz. Nothing the OS can do will change it. Enabling SpeedStep means that FreeBSD sees the full 2.0GHz. I've also heard about someone whose Dell had a broken BIOS, which meant that the CPU could never run at full speed, but was always running at 60%. Upgrading the BIOS was the solution in that case. -- Bruce Cran _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
