Does anyone know what the siren warning means on this board?

Configuration is dual Xeon 3GHz Processor, 2Gb Kingston RAM, etc. PC worked
fine for two months, then user reported a 'CPU Microcode error' displayed
and the PC worked really slow. Next boot a two tone repeating fast siren
sounds on power up, with no screen output.

My guess is a processor failure rather than the motherboard.

Can anyone confirm?

definitely possible, but also ensure both cpus are exactly the same
steppings etc
older microcode will run on newer cpus but not vice versa
i had an s2460 & 1 x mp1600+ replaced under warranty, the replacement cpu
was made from a different coloured substrate to the original, i would
receive errors when the newer cpu was in socket 0 but everything was fine
when it was in socket 1
try the cpus 1 at a time & investigate all steppings etc via wcpuid [i think
3.30 is current]
