Alright, I assume you mean that you've re-enabled your UMB's by taking out the X=A000-EFFF option, but NOVDS is needed for things to work. Otherwise VDS won't be an issue, since it's for remapped memory -- the UMBs -- and there won't be any UMBs present using X=A000-EFFF. The problem is that latest EMM386 didn't change VDS code, so you've probably have a slightly different configuration than previously. Something loaded high that wasn't loaded there before. Or maybe in a different order. You can verify that NOVDS is the solution by not loading any drivers in upper memory and see if it's still required. NOVDS should not be needed with no drivers loaded high. What would be best then is to see exactly which driver loaded high is causing the failure unless NOVDS is present. If I can get a copy of the problematic driver I can run it under a debugger or disassemble it and see what VDS calls it's making. Or if it has an basic incompatibility with being loaded in upper memory. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
