What's the first byte in memory? : <p>I'm writing an operating system, and I need an address where the value is NULL. I was thinking a really far address, but, does the BIOS use the first byte in memory? My kernel won't use it for anything besides the constant char NULL, so I was thinking the first byte might not be used, where a really far address might be, if you'd need to allocate a lot of memory.</p>
