hi
sorry I havnt had much time lately to work on this or keep you up t date. I have a bootsector working which gets drive geometry from int 0x13, ah=8, which solves the problems I incountered earlier. the bootsector also puts cpu into unreal mode and copies kernel.mnt to memory address 0x100000 and then executes kernel afterwards.
it works in that I get the blue menuet options menu at bootup but fails since the option to boot to image existing in ram no longer exists.
I believe I need to set it up so it loads the .img file to 10mb address then navigates the image in memory and transfers kernel.mnt from within the image file to 1mb memory address then add the option back to distributed image to executes in order to simulate normal boot sequence. that is if I can squeeze all that extra code into the bootsector.
