This was just out of curiosity question, loading from DOS is just a matter of development convenience for me and in all other situations the boot loader is used.
Yep. I understand that. The cleanest way i can suggest you is to let the "environmnent-specific" part of the loader to inform your OS of what memory region are available (both low-memory and high-memory), so that you can run your kernel safely in any environment (raw BIOS, bios with EBDA, DOS, DOS with HIMEM & SMARTDRV, etc)
