In most cases I've seen, this type of error message appears when the
OS/2 boot record has been successfully written to the C:  partition boot
record location, but for some reason the DOS C:\AUTOEXEC.BAT and
C:\CONFIG.SYS files are still in the root directory.

Boot from a floppy and check your C:\OS2\SYSTEM directory for *.DOS or 
*.OS2 files. When you are "correctly" in "boot DOS" mode, the 
following files should be present:

    BOOT.OS2
    CONFIG.OS2
    AUTOEXEC.OS2

If you are in "boot OS/2" mode (e.g. following a successful BOOT /OS2 
command), the following files should be present:

    BOOT.DOS
    CONFIG.DOS
    AUTOEXEC.DOS

I'd recommend making copies of the relevant files in the root directory
and C:\OS2\SYSTEM onto a flooy disk before doing anything else.  Once
you;ve done this, put the appropriate AUTOEXEC and CONFIG files into the
root directory of C:.  You should be able to boot at his point.

Next, if you've just booted OS/2, make sure DOS versions of the boot
sector, AUTOEXEC.BAT, and CONFIG.SYS are in C:\OS2\SYSTEM.  This will
let you switch back to DOS with the BOOT command.

Hope this helps...
