[comp.sys.ibm.pc] DOS 5.0 upgrade ?

john@wa3wbu.UUCP (John Gayman) (06/21/91)

   Does anyone know the difference between the DOS 5.0 upgrade kit and 
the entire release ?  It sounds like the upgrade kit has an automated
install routine which senses a prior version and automatically installs.
Does this mean you cannot install the upgrade to a freshly formatted
hard disk ?  Will DOS 5.0 allow you to run completely from floppy for doing
low-level disk type maintenance ?  There also seems to be a lot of
confusion about where exactly DOS 5.0 gets its extra memory, is it from
extended ?  I mean I have a older 8 Mhz 80286 with 640K conventional and
384 extended... will I realize the memory gain ?  I'd sure appreciate a
detailed explaination from someone in the know. Thanks!!

When I ran SETUP, it generated 4 3.5" floppies, the first of which DID
have the system on it.  I was able to boot off of this disk.  The VER
command verified that it was DOS 5.00, and a MEM verified that I did
have a great deal more memory available!
