I don't know why nobody tries to get *this* wall down; those DOS-expanders and DPMIs are work-arounds, not really next steps beyond the first primitive DOS.) >> Sorry, Heimo, unlike the Berlin Wall, this one will never come down. Closest jackhammers are programs like Qemm's memory manager which sets itself up between the CPU and Memory acting like an octopus traffic cop, 386 Max and the like. These scavenge unused blocks of memory like the monochrome video, etc. which add to the pile of memory available from the 640K left unassigned or reserved by the forefathers for devices and options heretofore abandoned. The dangers are the inherently unstable addresses reclaimed by these programs, which do not prove compatible with the programmers' selected choices causing freezes, hangs and other assorted oddities when called to use as usable addresses freed by said managers. Reason why DOS itself is a limited OP Sys, designed solely for the purpose of accessing drives and files and maintaining a heirarchy of said files. There should be an XDOS (extended DOS) that taps into ANY available memory on-board, which searches for modular memory pluggable onto the motherboards such as in the slot where the Math Coprocessor snaps, or on-board chip-cradles, etc. or added as a daughter board onto any older motherboard for 286, 386 which carries an Xtended Bios which searches and programs unused memory for use with XDOS.
