Usually this is because you have slow memory chips. Make sure that you system has at least 80ns chips (or 100ns if you have high speed cache on board). If you have slower than 80ns, the system will hang; whether you have 1 or 2 wait states. To tell, you can just look at the memory chips, the trailing digits will tell you the speed that they are rated at. __________ ___ / \ / / /_/ / /\/ _/ / / / __/. /__ / / / / / / / / "Happy Computing ..." / / Internet: Johnny.J.Chin@andrew.cmu.edu / ------- / 4730 Centre Ave. #412 BITnet: jc58@andrew \__________/ Pittsburgh, PA 15213 UUCP: ...!uunet!andrew.cmu.edu!jc58 Computer Dr. Carnegie Mellon University "If you don't like having backups ... try driving without your spare tire." ______________________________________________________________________________ Disclaimer: The views expressed herein are STRICTLY my own, and not CMU's.
