Once you've done that, you have the same capability as the more expensive standard version. I emphasize first time because you can use the DOS 5.0 upgrade version to create a standard, self-booting set of DOS floppy disks by typing the SETUP /F command. The standard version is self-booting (starting), so it can be used out-of-the-box to start a computer that has no DOS on it.

The difference is that the upgrade version can be run the first time only on a computer that is already running. Microsoft sells two versions of DOS 5.0 - a standard version for new computers and a substantially cheaper upgrade version for existing computers. That's true for any change you make in disk partitions, even if the changes create multiple drives of less than 32 megabytes each on the hard disk. You have to perform the DOS 5.0 upgrade in several stages, however, to take advantage of larger partitions. With MS-DOS 5.0, hard disks as large as 2 gigabytes (2,000 megabytes) can be given a single partition.

One of the many advantages of DOS 5.0 over its most popular predecessor, DOS 3.3, is the ability to have hard disk partitions larger than 32 megabytes of storage space. Upgrading your old DOS operating system to Microsoft Corp.'s new MS-DOS 5.0 can be a quick and easy task - unless you have a hard disk larger than 32 megabytes.
