Maintenance Partitions (Revised)

Now, shutdown and restart your computer. When the Boot Manager menu is displayed,
select the maintenance partition by using the up and down cursor keys, and then
press <Enter>. The OS/2 logo will be displayed, then you should see a command
prompt. Your maintenance partition is up and running and if you check you'll find
it's only using around 9 MB! In addition to OS/2 itself BootOS/2 has copied several
utilities to your maintenance partition. Most of them are located in the OS2 directory
and they include Fdisk, Chkdsk, Format, Attrib, and Tedit--a simple, but powerful
text editor. Try running Chkdsk on your boot drive. To do that before you would
have to boot from the installation disks, and then hunt through the disk images
for the Chkdsk program!

Clearly there are many things this simple partition cannot do. There is no
GUI interface, you cannot even run Rexx programs, and it doesn't support DOS programs.
By using the BootOS/2's parameters you can add more functionality to this simple
OS/2 system. For example you can add REXX to the command line to get REXX support;
similarly adding WPS and HELP get the Workplace Shell and basic Help. See the file
BootOS2.doc for complete information.
Beyond what BootOS/2 will install, you can install your own applications, as long
as you don't get carried away. For example I have installed Partition Magic 3.05.x,
BackAgain/2, Kon, and ZipCntrl on my partition. Being able to use the
full GUI version to do backup and restores of the system drive is a big advantage
over having to use the basic text version. I also use the maintenance partition
to restore the Desktop when necessary. (Note: the OS/2 Enhanced Editor, EPM, is
not a good candidate for installation on the maintenance partition because it uses
a number of system functions, which in turn require components of OS/2 not installed
by BootOS/2.)
If you decide to install your backup software on your maintenance partition,
consider installing the files on the same drive and directory you placed them on
when you installed it from your main boot system. This will avoid problems that
might arise if both the main backup and maintenance partition backup software require
data files that need to be synchronized, such as the tape id and catalog files BackAgain/2
uses. One final tip: if you do install your backup software on your maintenance
partition, I suggest you split your full backup procedure into two, and switch to
your maintenance partition to backup your main boot drive. Doing so will enable
your backup program to reset the archive flags on all files, leaving fewer files
to back up during the differential or incremental backup procedures on successive
days. This is especially important if you use differential backups.
I hope you'll try building a maintenance partition if you don't already have
one. If you run into some snags or have questions, please don't hesitate to contact
me by email. Having a well thought-out maintenance
partition will do a lot to make your OS/2 experience both more productive and more
enjoyable.
