CPU Missing on Dell 1550

Archived from groups: alt.sys.pc-clone.dell (More info?)

Is there a requirement to have two CPUs on the Dell 1550? When we remove
the second processor, we get a "CPU Missing" message followed by a System
Halted.

    There could be two problems. Most multi-processor MBs require a
    'terminator' in the 'unused' CPU socket. (Not all do, but many!) The
    system documentation should tell you if that is true.

    The second issue is the "CPU Missing" message and the "System Halt"
    are possibly from the operating system. There is a process for
    changing the HAL (Hardware Abstraction Layer) in windows to account
    for multi vs. single processors. Not a trivial thing to do, especially
    since it requires modification of the basic system.

    But... I gotta ask: "Why are you removing one CPU?"

    No OS starts to load. System Halted is coming from the BIOS.

    We removed one CPU because on startup we were getting an immediate (and
    false) error message from BIOS about a CPU overheating. We wanted to
    isolate whether we had a bad CPU or a bad motherboard heat sensor.

    Is it a BIOS error or OS error? Does it occur as the OS loads? Sounds like
    it is HAL related and the HAL is configured for two CPUs. You can try
    reinstalling the OS.

    It is without question a BIOS System Halt. No OS even starts to load.

    Did the message say which CPU was 'overheating'? If yes, then swapping
    may give some idea as to what is up.

    I'd guess a sensor has failed, but I am not sure.

    Can't you turn the overheat warning off in the BIOS? Seems to me on my
    poweredge servers you can do this (but I'm not 100% sure!)

    you need to have two CPUs in the machine or a terminator in the unused
    socket
