@tadziuuu Are you referring to booting bios based computers? If yes then use memdisk to load the cd iso image into memory. The one caveat here is that the iso disk must be less than 2GB in size since memdisk is a 32 bit application and there needs to be room in ram for the OS to boot from the iso image. In the same tutorial you found the parameters in your first post, search for memdisk to see what parameters you need.
