If you are using RAM without any parameters, EMM386 should not behave any differently than if it didn't exist. Standard UMB area scan occurs whether RAM is there or not. Only the optional range with RAM makes a difference, changing the default scan area size. And if you know your non-default range that well, why not just I= include and X= exclude within it?
I still see scant evidence that RAM is anything but a weak option needed almost solely for minor MS-DOS compatibility sake. For compatibility reasons alone RAM should be in there, but not as a pressing issue. Same deal with HIGHSCAN and others. What makes the grade for adding to the option list right now, as a user-driven priority need?
long term request, I guess. No need to implement it direct. Lower priority than VDS for example, but easier to implement.
..Except maybe that MS users may see a warning about the RAM parameter ("hey, it's required in MSDOS, and now this replacement complains!!!")
as Erwin demonstrated, FreeDOS apps should be, in best case, complete replacements instead of clones.
(he uses FreeDOS kernel and MSDOS kernel on his Netware disk, but prefers FreeDOS programs as they are smaller + version independent)
That means for example the line DEVICE=C:\DOS\EMM386.EXE RAM I=B000-B7FF in config.sys
and then it should not matter if I replace the emm386.exe from msdos by the freedos version.
a clone has the same functionality as the original, but only on the freedos platform. SYS for example, or unfortunately, FORMAT.
What FreeDOS SYS could do if placed on a MS bootdisk would be:
-take MS bootsector from source drive
-insert it into bootsector area of target drive
-patch the details so it works for harddisk.
-copy io.sys/command.com/msdos.sys
(as the freedos bootsector does not allow to boot msdos, we need to copy/patch the MSDOS bootsector for MSDOS operating system)
