| E : The DOS Plus Transients |  |
||
 |
The following shows the contents of the DOS system disc as supplied in release 2.1 of DOS Plus. You should note that, if you are using an earlier issue, your own disc will not contain all the files shown here, and will in addition show one or two extras, most notably the File Manager, FMG.CMD. This has been withdrawn by Digital Research and is no longer supplied. A copy taken from release 1.2 appears to function on 2.1, but users should note that this is not a recommended practice, as filemanager is known to be unreliable, hence its withdrawal.
If you are using an earlier release of DOS Plus than 2.1 and wish to obtain the upgrade, see Appendix A for details.
The file data is shown exactly as catalogued, with inserted column headings for clarity, and brief comments on the purpose or use of the file, to give help if you are deciding which might need to be copied to your working floppy discs or memory disc. By adding up the file sizes shown (remembering to round up to the correct size for your disc format) you will be able to see in advance the amount of space which will be required. In practice it is just as easy to copy the required files to an empty disc and issue a 'DIR' command, if the system is available at the time.
DISC 1 is the DOS Plus systems disc, required initially to boot the system prior to making your own working copy. You should immediately make a working copy and use this copy in all future operations, retaining the original safely in case of disaster.
This disc contains all the transient commands and utilities required by the 512 in running DOS Plus. You may find it useful to copy selected utilities to your applications discs, or to ensure their availability by means of the memory disc, and setting the appropriate path.

| COMMAND.COM | 26888 | 6-01-87 | 14:28 | The transient which decodes all command input. It's more or less invisible, but can be overwritten by applications.

| DISK.CMD | 16512 | 15-07-87 | 11:58 | This is the disc copy, format and verify utility. You should use this instead of COPY, if you want to copy the SYS files to make another bootable disc. |
