Dos 2.5 And Your Ataai Personal Computer System - Atari DOS 2.5: XF551 Owner's Manual

DOS 2.5 and Your ATARI Personal
Computer System
With
just a few restrictions,
DOS 2.5
is
compatible with the
earlier
AlAR! DOS 2.08.
You can also convert DOS 3 files to
OOS 2.5
formats.
This means that you can use DOS 2.5 to
manage files originally stored and managed using the older
versions of DOS.
You can use OOS 2.5 with the AlARI XF551 and the ATARI810™
Disk Drives. However, your system must include at least
one XF551.
DOS 2.5 allows you to format diskettes and store information
in either single or enhanced density. With enhanced density
you can record about
50
percent more data on each diskette
than you can with DOS 2.05. But you can manage enhanced-
density storage only
if
you have an
AlARI
XF551 Disk Drive;
the 810 Disk Drive is not capable of formatting or managing
data stored in enhanced density (including the files on your
DOS 2.5 Diskette - this is why you must have an XF551 Disk
Drive to begin working with DOS 2.5).
If
your computer sys-
tem includes an 810 Disk Drive that you will often use to
access your files, you may want to format all your diskettes
in single-density.
Note: DOS 2.5 woo<s exactly the same with both the ATARI
XF551 and 1050 Disk Drives. If you happen to be using this
manual with an ATARI1050 Disk Drive you can substitute
"1050" for "XF551" in all sections discussing DOS 2.5.
If your system includes both an XF551 and an 810, and you
are using DOS 2.08 files with DOS 2.5, see Appendix H.
If
you
are working with DOS 3 files, see Appendix L.
With either or both disk drives, use single-sided, double-
density diskettes.
