Richard Bonner :
As I wrote, its kernel has more bugs and is slower. But you can experiment
with anything labelled as FreeDOS also staying with the EDR-DOS kernel and
if you wish, its (of EDR-DOS) COMMAND.COM. See http://www.yqcomputer.com/
for more information, downloads, forum, etc. Note that because the sources
of anything but the kernel for DR-DOS are not available, EDR-DOS uses some
FreeDOS utilities like SYS and FORMAT too.
