Basic Installation ? (Solved)
« on: August 21, 2014, 11:34:34 am »
Two questions from a daft old bugger who has lost his way  :'(
One - is there a 'Net Install'  iso download ?(I'm sure there used to be)
Two - How do I check whether I'm running 64bit or not?

I searched the internet and found one of the answers, didn't find the network iso

Try
Quote
uname -m
. It seems like the uname -m actually gives

x86_64 ==> 64-bit kernel
i686   ==> 32-bit kernel

Otherwise, not for the Linux kernel, but for the CPU, you type:

Quote
cat /proc/cpuinfo

or:

Quote
grep flags /proc/cpuinfo

Under "flags" parameter, you will see various values: see "What do the flags in /proc/cpuinfo mean?" Among them, one is named lm: Long Mode (x86-64: amd64, also known as Intel 64, i.e. 64-bit capable)

lm ==> 64-bit processor

Note: you can have a 64-bit CPU with a 32-bit kernel installed

If you were running a 64 bit platform you would see x86_64 or something very similar in the output from
Quote
uname -a

To get your specific machine hardware name run

Quote
uname -m

You can also call

Quote
getconf LONG_BIT

which returns either 32 or 64

Two - How do I check whether I'm running 64bit or not?

1. Not in Sparky at least. The installer runs locally. There were some aspects of downloading packages from the net (translation packages mostly), but none of it remains for the time being. Maybe in the new installer that we're planning, that will merge the old and the current one and add some more functionality.
2. "uname -m" should do the trick as @way12go suggested.

Furthermore: for determining if you're running a BIOS-booted or UEFI-booted environment refer to the contents of the /sys/firmware directory. If there's a "efi" subdirectory with content inside, then you're running an UEFI-booted environment. Hmm... I guess this will be useful information for the bug reporting tool (arch and either UEFI or not).
There isn't a single thing that's impossible. Just the things that we don't yet know how to deal with. ;)
