Apologies for writing to you again. But, my purpose of this code is to write 'Alux' to RAM, then read it back again.
Done.

What for? Putting 'Alux' in some random spot of kernel memory would crash the machine.

I used to do similar things on the Commodore 64. There was a 'poke' command.
The commodore 64 had no memory management, few to no sensible programming languages, and no kernel, just a BIOS. You could get away with poke-ing random things, and frequently had to to get around language and BIOS limitations.
Linux has proper memory management, which makes poke kind of pointless. It also has a kernel, which gives you much, much better ways to do what you want than poke. Nobody has to poke anymore, there's no point.
Modern I/O is a lot more complicated than that, anyway. There's not a lot to be accomplished by poking random addresses.

I wish to install Red Hat linux 7.1 on a machine with 16mb of EDO Ram. When I enter the instalation process I am told 'You do not have enough memory'. Is there a way to install RHL with only the 16? Or will I have to upgrade and buy some very expensive EDO.
