That's right; that frequency is the i8254, not the TSC. (Don't ask me what both of these are, I just know that they're different things and that the frequency above is correct for the i8254.) > It is actually a 486DX2/66.

I think only 586s and above have a TSC, so the machdep.tsc_freq sysctl may not exist, or may be meaningless. -- Ben Smithurst / ben@scientia.demon.co.uk / PGP: 0x99392F7D To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
