There are many, at least for loading, about reliability, I know only FreeDOS DEVLOAD and it seems reliable (but no unload)

No it isn't. It's just uploaded in FreeDOS area at ibiblio, and there is no source code. Even worse, it's from 1991, so from a time when FreeDOS didn't exist at all

Also, FAT28 support apparently broke many such "block-device" things, and FreeDOS DEVLOAD is possibly the only one that still works, in both FreeDOS and EDR-DOS

Finally, much better than such DEVLOAD/DEVUNLOAD hacks, is of course to include the load and unload feature into the primary project and design it as unloadable TSR instead of SYS, as done in Bret's USBDOS
