Can it load everything above the 1M mark? My problem is that the Everex card can only fill memory extended memory starting from 1M. In fact we have now got 1M extended memory and 3M expanded memory on the card. However, there is *no* memory between 640K and 1M. Will I be able to get more than 600K out of the DR-DOS? If we use window3, and load himem.sys, will DR-DOS stop loading drivers, etc to memory above 640K? > >It also allows the user to specify whether to copy slow BIOS code >to faster RAM... (I am a little unclear on what "shadow ram" >means...;-( "Shadow Ram" are memory between 640K and 1M, which are being used to *shadow* ROM or VIDEO BIOS, according to C&T. -------------------------------------------------------------------------- L.N.
