If the device is indeed a Pentium Pro, then there may be a bug in your BIOS. Note that Pentium II processors are also identified as Pentium Pros, and these are available in 333MHz grades. If you have a PII which your BIOS is claiming runs at 333MHz, but the boot-time calibration reports 233MHz, then you have either: - motherboard jumpers set incorrectly, confusing the BIOS. - a BIOS bug. - a motherboard bug. - faulty motherboard timekeeping hardware. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
