I have found out what to do, think I should share it for you all that is novice like me. :)
First of all, start open firmwire by holding down "command + alt + o + f" on startup until you see the OF screen.
To determine the partition number of the HFS boot partition where the bootinfo.txt file is located type the following:
dir hd:x,\\
where x should be a number of the hd partition, in my case I found the first partition at number 2.
when I wrote "dir hd:2,\\" I found a list files, among them the "bootinfo.txt and by that I new that this is the partition I was looking for.
Now type:
setenv boot-command boot hd:x,\\bootinfo.txt
Now save the changes and reboot by typing:
reset-all
Now enjoy booting directly in to MorphOS 3.3 and feel the incredible boot speed!
