Hummm, I think that is the CPU is missing/dead, you would get no beep.

Reading this thread, someone else mentioned beep codes and that if there were none, it's most likely a fried motherboard. Can anyone else confirm this? Beep codes may be available, but the nature will depend upon the manufacturer and the BIOS. Different manufacturers will produce different products. In the bad old days the most common beep codes were designed to indicate a video BIOS did not initialize, and then the main area of codes indicated something wrong in the memory subsystem. Pretty much if they made it past these two points the board would boot. And, of course, you need a speaker hooked up which I commonly don't because I don't want any beeps. One thing to be aware of with regard to modern day motherboards and power supplies. I don't recall the exact standards nomenclature, but they are spelled out in a spec. Modern day motherboards will have a main power connector with either 20 or 24 pins. Some are wired so that a 20 pin power supply cable can only go into some of the pins of a 24 pin connector, leaving 4 open. Some power supplies have a split cable which has a 20 pin and a 4 pin that can be hooked together and will occupy all 24 pins of a 24 pin connector. In either case, there is also another second power connector which is usually fairly close nearby to the CPU socket. With slightly older boards this will be a 4 pin and newer boards it will be an 8 pin. On older power supplies there may be only one 4 pin cable designed to plug into this connector. Newer models will usually have a cable that splits into two 4 pin plugs, so as to be able to plug both into an 8 pin socket while retaining backwards compatibility with the older 4 pin boards. This second connector goes to a high current 12volt rail within the power supply and drives all those 'multi-phase' regulators near the CPU. One thing that is consistent is motherboards will not even attempt to boot if this second power cable is not connected or cannot supply sufficient amps. Some power supplies may even beep or have an LED that flashes red. Overlook this and the board will never boot. -Mike ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Olivier I thought this as well, although googling shows that quite a few motherboard BIOSes will beep if there is a missing or dead CPU. I'll have to double check this, since I don't know the model number of the board. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

If at any time those dual-digit LEDs stay permanently on anything OTHER THAN 00 is a failed POST. If it fails before it gets a shot at testing RAM or anything, there may be no beep codes. Always good to have one in a toolkit. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Many high end mobo's need a power supply that feeds a steady current. The component detection on the better mobos will shut the board down if it is not the quality tolerance it likes. We just experienced this here two weeks ago with all new components and the supplier of the components replaced the brand new Power Supply with a better quality one at their expense and the box works fine now. This was a mother board that was not cheap. My wife needed to upgrade for video editing etc. The supplier said they had this problem with several of the better boards. ~Al Plant - Honolulu, Hawaii - Phone: 808-284-2740 + http://hawaiidakine.com + http://freebsdinfo.org + + http://aloha50.net - Supporting - FreeBSD 7.2 - 8.0 - 9* + email: n...@hdk5.net All that's really worth doing is what we do for others.- Lewis Carrol ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I figured they had something to do with the BIOS, but I was just too lazy to find out. ;) Learn something new everyday.
