:>I never knew about the 4096 or 8192 rules.

I have never found this rule to fail. 4096+ BNDRY=PAGE virtual was always cleared. It prevented the need to force slot assignments for pages that may never be needed via a big MVCL to clear the area. I wonder if VSM is smart enough to recognize that a paged out page is all zero and to just mark it as not assigned yet so that a page fault will not require a page in. -- Binyamin Dissen <[email protected]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
