Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 0.89.1i X-Operating-System: FreeBSD 2.2.5-STABLE i386 Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi, just curious where CLK_USE_I586_CALIBRATION went ?? I used to use in my PPro, but not config (and LINT) tell me it's no longer an option. With the I586_CALIBRATION the boot message would correctly detect the CPU speed each and every time. Now it's off by +/- 15%, and my clock has gained over an hour in under a day.. :-( What should I be using here?? I have the CLK_USE_I8254_CALIBRATION option in the kernel right now. Maybe I should have nothing "extra" in there?
