I just tested with the following configuration. I am able to boot from the 3 system floppy images without issue. Best guess at this point, try upgrading to 4MB RAM. Maybe it's a requirement for V5.0. I've never seen a system with less than 4MB. Tony --------------------------------------------------------------------- Fluke 9100A.
