Yes.  Probably the easiest way is to use Boot Manager.  Boot from the OS/2 
install discs, choose advanced installation, and choose to manually select 
the installation drive.  When the installation program runs FDISK, as it 
will, install Boot Manager, create a single FAT primary partition on drive 0, 
and create a single primary HPFS partition on drive 1.  Add both partitions 
to Boot Manager using the menu.  Save your changes and exit, but don't bother 
completing the OS/2 installation process just yet.
Reboot and install DOS on the primary FAT partition on drive 0.  This will 
disable Boot Manager.  Boot from the OS/2 install floppies once more and 
install OS/2 to the primary HPFS partition on drive 1.  You will have to use 
the advanced install, since the easy install assumes that you are installing 
OS/2 to the primary partition on drive 0.  This will have the side effect of 
re-enabling Boot Manager.
Whenever your machine boots from then on, Boot Manager will be given control 
first, and you can choose whether to boot DOS from the primary FAT partition 
on drive 0, or OS/2 from the primary HPFS partition on drive 1.
Although there are lots of things that one should be aware of when coming 
from the DOS world (OS/2 is not DOS, and does not share many of its quirks 
and limitations), two things to note are that (unlike DOS) OS/2 can be 
installed on and boot from any partition of any drive as long as you use Boot 
Manager, and that when you have the option of using HPFS and Boot Manager, 
rather than FAT and Dual Boot, as you happen to do, then it is _strongly_ 
recommended that you use them.
