Hi,
I'm not exactly sure of what you'd like to achieve but I had a problem in the past of Dual booting my machine between Linux and OS/2. Pls check in past forums re using OS/2 Boot Manager to boot multiple OS's. Both El Vato and Obiwan posted some very good and detailed howtos there. Alternatively you can try AiR Boot from the following link :

Hope this helps.
John.
