No, it's not a typo, I really have >645k free, it is definitively conventional memory and I am really running >Dos 3.3. > Wow, that's a good trick. How can you do that with only 640K of "conventional memory" to start with? Are you using the first 64K of "high memory" (640K-1M) as "conventional memory" which precludes the use of some video modes but gets you 704K? .---------------------------------------------------------------------------. : Jim Schwalbe .----------------.
