um... well, aslong as you don't go over 5k, code it in Fasm and it don't blow up computers... I see no problem with it... as long as you right the kernel I see no reson for you to use your own bootloader, use any bootloader as long as it is open source... thats it me.... and, dump the rest on the first page, add all the apps you want..

I just call it test
