- Note - this same help file is available both from the menu for
- making a Recovery disk, and for using a Recovery disk. So when
- reading the file, please bear in mind your current context.

- What's involved when making a Recovery
- Disk, and when using a Recovery Disk.
-
-
-
- ───────────────
- FOR CONVENIENCE

-
- This same help file is also included as a Help on the Recovery Disk
- RESTORE Menu, to remind you about these two important .COM files when
- using the Recovery Disk.
-
- COMMAND.COM is the main Dos computer operating module. It loads
- automatically whenever you boot your computer, whether from the
- Hard Drive or the A: drive.
-
- Dos has two other main operating files; IO.SYS and MSDOS.SYS .
- These are the two hidden files which are placed on any disk you make
- bootable by formatting the disk 'with system'. For example, a bootable
- floppy disk contains both files, and when your main hard drive was
- originally formatted by someone, it was formatted 'with system'
- to have the two files.
-
- SYS.COM is used to copy these two booting files to a boot disk if
- needed, as an alternative to re-formatting the disk 'with system'.
-
-
-
- It is not uncommon for a virus to corrupt COMMAND.COM. Similarly
- somtimes other damaged files can do the same thing, making your
- computer operate incorrectly. Similarly, some viruses can hole
- up in the two hidden system boot files, making it seem like the
- virus continually returns from nowhere no matter what you do to
- try to remove it.
-
-
- Therefore, the following is a simple suggestion in order to
- illiminate the possibility of a lot of undue frustrations from
- either or both of these two contaminant sources, when trying
- to remove a virus or recover from a disaster.

- TOPIC 2 RE: COMMAND.COM
- ════════════════════════════════════
-
-
- Usually, COMMAND.COM is present in the computer's root path, ie, C:\ .
- Similarly, it is also usually in the Dos subdirectory of the computer.
-
-
- SO ::::
-
- When you exit this Help file and exit Recovery Disk, go to the Dos
- sub-directory and copy COMMAND.COM to the Recovery Disk. Whenever
- you use the Recovery Disk, when finished using the RESTORE Menu on
- the Recovery Disk to restore the computer's regular records, simply
- re-copy COMMAND.COM to the root path.
-
-
- That is, (for instance),
- at the A: pompt type and enter:
- \
- COPY COMMAND.COM C:
-
-

- TOPIC 2 RE: SYS.COM
- ════════════════════════════════
-
- SYS.COM is usually found in the Dos sub-directory. So, like
- COMMAND.COM, after exiting this help file, go to the Dos
- sub-directory and copy SYS.COM to the Recovery Disk.
-
-
- BUT - do this only if you have made a bootable Recovery Disk using
- the Saga 300O option. This is because the job of SYS.COM is to
- automatically copy the two hidden boot files IO.SYS and MSDOS.SYS
- to a boot disk, and these two files are only found on a bootable
- disk.
-
- In other words, if your Recovery Disk is not also a bootable disk,
- (i.e. you used the Turbo 2000 option), SYS.COM won't be able to do
- anything, so don't bother copying SYS.COM to the Recovery Disk.
-
- Instead, when finished using the RESTORE menu on the Recovery Disk
- to restore the computer's main records, put a clean write protected
- boot disk in the A: drive and type and enter:
- \
- SYS C: (assuming your hard drive is C:).
-
- However, if your Recovery Disk is also a bootable disk, (ie. you used
- the Sage 3000 option), then copy SYS.COM to the disk (if SYS.COM is
- available), and after using the RESTORE Menu on the Recovery Disk to
- restore the computer's regular records, run SYS.COM directly from the
- Recovery Disk.
-
-
-
- ░ Note - make absolutely sure that any SYS.COM you use
- is from the same version of Dos that was used
- to originally format your hard drive.
