Before dos boots we get the message "1800mhz Pentium 4cpu, External cache 512mb installed" displayed with a continuous beep of about 20 seconds. The beep does not match any beep codes for the bios. The laptop is a Fujitsu c series lifebook c1024. I have booted with out a hard drive to confirm was it was not an instilation issue and reseated the hard drive and ram. I need a quick response and high points will be given for working solutions!
