    Re: system boots into 32-bit mode; want 64-bit mode

    sds57, I hope you will forgive me, I am not trying to hi-jack your thread, but I think I can learn something if I can understand what is happening to you.

    I looked up 'uname -m' in the man pages and that said it would print the machine *hardware* name. I am guessing that means the processor.

    Wouldn't this just change your software:

    Those are the instructions to do a clean install of your operating system. I have done that a few times.

    If "uname -m" is a *hardware* name, I don"t think that would change it.

    Am I right that the terms "32 bit" and "64 bit" can be applied to either processors or the Operating Systems software being run on them?

    Are you trying to figure out what type of hardware you have or what operating system you are using?

    If I am out of line being curious about this thread, just don't answer me.

    Good Luck with what ever you are trying to work out. Eldera

    PS How much RAM do you have? I read in Keir Thomas Pocket Guide that unless you had a minimum of 4GB of Ram that you did not get the full advantage of a 64 bit OS. I have run my Pang with both the 32 bit and the 64 bit OS and it did not make any visible difference. If everything else is working well, why worry which OS is on it?

    Yes. 64-bit processors are backward-compatible - they can run both 32-bit and 64-bit operating systems. 32-bit processors cannot run 64-bit operating systems. 'uname -m' gives the architecture of the operating system.

    Thank you. I understand now. The man page was confusing me. Have a great day.
