Hello, I recently downloaded Mycan's Mycan''s MS-DOS 7.10 Bootable CD and used it to boot. I found that after loading Ntfspro5, Quickview2.5 can no longer be loaded; it says there isn't enough memory. I'd like to ask whether there is any method or software that can increase memory under DOS (my RAM is 512mb). Of course, 512mb would be best. Thanks!

Then may I ask, moderator, is there any way to increase conventional memory? For example, increase it to 100MB... Thanks!

Does upper memory have a size limit? Or is it limited together with conventional memory? Thanks!
