For those of you who have a CD-ROM which is unsupported by 2.1, but would
like to install the CD-ROM version of the 2.1 Upgrade (because it's cheaper
and has more multimedia stuff on it) without resorting to diskettes then
here is the method I used. If you have a free 32MB on a partition on a hard
disk then you can install from the there. Here's how:

1. Boot DOS.
2. Copy the entire OS2SE21 directory and sub-directories, intact, from the
CD-ROM to the root directory of the hard disk partition. Do not copy to a
hard disk partition which you intend to format during the 2.1 Install
procedure. I happen to have 2 hard disks, so I copied to a FAT partition on
the disk on which I wasn't installing 2.1. I would expect, though I haven't
tried it, that you could copy the tree to your OS/2 2.0 partition if you
didn't intend to reformat. [The easiest way to copy the tree is to use a GUI
File Manager to copy from the CD-ROM directory tree to the hard disk tree.]
3. Insert the OS/2 2.1 diskette labeled 'Diskette 1' (1 of the 2 disk set which came in the 2.1 Upgrade package with your CD-ROM) into your floppy drive.
4. Make a copy of the CONFIG.SYS file on the diskette [>COPY A:CONFIG.SYS
CONFIG.OS2]. Copy the CONFIG.SYS file from the \OS2SE21\DISK_1 directory of
the CD-ROM to the diskette - overwriting the CONFIG.SYS on the diskette.
5. Use a DOS editor to open the CONFIG.SYS file on the diskette. Add the
following lines to the end of the file after the statement
'device=\testcfg.sys'.

     set os2_shell=sysinst2.exe x:\os2se21
     set source_path=x:\os2se21
     set saveconnect=1

where x is the letter of the hard disk partition to which you copied the
CD-ROM files.
6. Add the following to the end of the line which starts 'path='. This
statement is found near the middle of the CONFIG.SYS file.

     ;x:\os2se21

where, again, x is the letter of the hard drive partition.
7. Save the edited file.
8. Close the editor.

You are now ready to install the OS 2.1 upgrade from a hard disk. Follow the
installation procedures outlined in the OS/2 Installation Guide. Anytime
during the installation procedure, if you are asked for the drive from which
you are installing from, reply with x:\OS2SE21 where x is letter of the hard
drive partition. Sit back, put your feet up and peruse the OS/2 manuals as
the installation proceeds with almost no intervention from you.

This is the method I used and it worked flawlessly.

Installing MMPM/2 is even easier. Just copy the directory tree from your CD-ROM to the hard disk and install from there.
