- dmwilcox 1y agoI think it is this, it's been a couple of weeks: nasm -f bin -o foobar.com foobar.asm Top of the file you'll need this offset for DOS (or 7c00 for an MBR) to adjust your pointers with based on where the program gets loaded: [bits 16] [offset 100] I bet you can use more than 64kb of memory, I set ES to A000 and write to video memory in mode 13. So I imagine if you have a data source -- know your (LBA) block offsets (MBR style) or use a DOS interrupt to load a file -- you can still stomp on some memory outside of the given 64k and set your DS register there. I haven't done it yet but if I wanted to load a .wad file or something that's the line I'd follow ;)
