Please excuse this question, but it's something I would like to know, what is a 64 bit OS? What makes an OS 64 bits? Is it that 64 bits can be addressed by the OS? Is it that all instructions are 64 bits in nature? Is a 64 bit OS created just by changing a compiler flag when compiling the OS? Oh, yeah, Haiku is cool. It is fast. Love that speed. You, the community, are doing a great job. Thanks, g.
