Okay, so the bootloader are located at 7c00 to 7e00, right? 7c00 + 512bytes?
Are there any more reserved addresses? Can i overwrite 7c00 later when i've left the bootloader?
I want to use up all my memory, starting from the very first sector/address, is the first 0000:0000?
Thanks
reserved addresses in memory besides 0x7c00

When your boot loader is no longer needed I do not see why not.
You may want to take a look at thist: http://mirror.href.com/thestarman/asm/d ... ments.html
It will explain memory segments fully, or atleast start you off.

Thanks coddy.
I understand how it works, just not which address to start with but your link seems to explain it.

I'd check Hobbes links again, The "Memory Map (x86)" link seems to have the answer in it. Not als well explained, but it gives a good memory map.
It may actually explain a bit more.

As it turns out, people who deny STFWs or RTFMs in advance actually never properly do their homework. And IMSNHO, posting a listed FAQ question with that in your signature borders on trolling.
