Quote: The FC-9801V in Chris's machine has developed a bizarre fault. If left unpowered for >28 hours it will boot (apparently) normally, but it will not re-boot if switched off and powered on again within around 28 hours of switch off, and it will not reboot if the reset button is used while powered on. When it fails to boot it generates a sequence of three "beeps" - presumably an error indication - and the processor READY signal is then found to be held low. I had an almost identical problem with an INTEL Server of ~2000 vintage. I never fully identified the cause but swapping out the Power Supply solved the problem long enough to get all the data off it and port everything to a new PC. As far as I know swapping the Power Supply may have solved the problem, but as the Server is now redundant I have not bothered to test it. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
