Perhaps if the CSST works on two adjacent fullwords while the other CPU does a block concurrent doubleword load? -- Binyamin Dissen <bdis...@dissensoftware.com> 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.
