Bootloader does not seem important to me, except if something needs to be initated in real-mode.
That's my point, kind of. If it doesn't seem important to you, then instead of doing a quick hack, you're better off using something existing instead.
But if you do decide that you need, or absolutely want, your own bootloader, then do it properly, which automatically makes it a reasonably large project of itself - that is, something almost like an OS. A bootloader that doesn't look like an OS at all has most likely too little functionality to be a good bootloader.
Kevin, if you speak the way you spoke with me in quoted post every day with adult people unlike me, you would quickly lose your head in less developed countries. True story. That's how my uncle got killed in 1999.
I'm not entirely sure what you mean, but I'm lucky enough to live in a country where it's generally considered okay to call a quick and dirty hack what it is. (And just to avoid any misunderstanding, I am not calling Pure64 such, but the typical 512 byte thingy from bad tutorials which don't advise beginners against writing their own bootloader.)
