Lines: 14 I am running Ultrix 4.0 on a DECStation 3100 with 24MB of memory. The PROM code recognizes and tests 24MB of memory, but when Ultrix is booting up it insists that there is only 12MB of memory. Why? /vmunix is configured to expect 24MB ("physmem 24" in the config file). Is there something more I should do to tell Ultrix how much memory it has? Is there something it looks at in the hardware and there's not a doggone thing I can do about it? This is a fairly recent upgrade from 3.X, and if I remember correctly the earlier version did indeed recognize all 24MB (but I'm not positive about that). Did I waste my company's money on 12MB of memory? -- Dave Robbins GTE Laboratories Incorporated drobbins@gte.com 40 Sylvan Rd. ...!harvard!bunny!drobbins Waltham, MA 02254
