21:39 < BrandonW> I think I might've killed my 73.
21:44 < _aegis_> aw, what happened?
21:50 < BrandonW> I think it's okay.
21:50 < BrandonW> Corrupted the archive so the 83+ OS wouldn't boot.
21:50 < BrandonW> But the 73 OS boots, so I'll just erase the archive sectors from there.
21:52 < BrandonW> Fortunately if I screw it up so badly that neither OS boots, all is not lost.
21:52 < BrandonW> There's a buffer overflow exploit you can do which will force the boot code to execute anything you send it.
21:53 < BrandonW> I say buffer overflow, but really it's just writing junk until you get all the way to the stack, which lets you change the address it'll return to, which means you can direct it to code you sent earlier.
21:53 < BrandonW> They do no bounds checking whatsoever on the packets you send...idiots...
21:53 < BrandonW> Although it's kind of strange, because you have to overwrite all of RAM to get there, including the checksum, which has to be right or it won't return.
21:54 < BrandonW> So you have to have the checksum itself be part of the...checksum calculation...
21:54 < BrandonW> My head almost exploded when I originally wrote it.
21:54 < BrandonW> But it does work.
21:55 < BrandonW> I believe that's how I dumped OS 1.3004.
21:55 < BrandonW> Since you can't execute code with it.
21:55 < BrandonW> I had to come up with a way to execute code that didn't involve overwriting the OS.
21:55 < BrandonW> Maybe I used the backup method for that. I can't remember.
21:56 < BrandonW> And even then I could've used the 73 Calcsys.
21:56 < BrandonW> So it was overkill, but I'm glad I did it.
