Message-ID: <1991Jun28.124744.27009@jet.uk> Date: 28 Jun 91 12:47:44 GMT Organization: Joint European Torus Lines: 16 When you run emm386, it always seems to run DOS in virtual 8086 mode. If you are only using emm386 in order to make upper memory blocks available, which do not need paging or any other facilities of protected mode in order to be accessible, is it possible to prevent it moving the 386 to virtual 8086 mode ? I.e have emm386 make UMB's available, but leave the 386 in real mode. There are two reasons for wanting this: 1. Virtual 8086 mode is slower for certain operations. 2. You cant run software that likes to switch in and out of protected mode itself. -- - Colin Manning, cm@jet.uk - Disclaimer: Please note that the above is a personal view and should not be construed as an official comment from the JET project.
