Depends whether you've got a 32 (i386) or 64 (x86_64) bit machine; that's what those 2 options are...

I've got core2duo laptop and dell gx280 desktop.

as i googled lil bit ( i hope em right ) isn't i386 machines outdated like now everything comes 64bit support? in addition i found while googling that x86 also means 32 bit, if so, Y we have seperate option for i386 as x86_64 covers both?

Not all machines are 64 bit, hence the option for both.

Also, please type out your words and do not use texting shorthand, ie "gna b da best option for me." should be "going to be the best option for me."

i found this on board,

Quote:
I'm no Linux Ninja or anything, but I do beleive that I386 means that the software is built and optimized for 386 class and up machines, x86 means it runs on the x86 architecture (286,386,486 etc) and x86_64 means that it runs on the 86 architecture aswell as the new Athlon 64 bit systems. I hope this helps, and of course, dont quote me on anything.

hi sudo_su,

the easiest way to check if your system is 32 or 64 bit is to open a terminal and type
Code:
cat /proc/cpuinfo | grep flags
if in the output that you get there is a flag named lm (stands for long mode) then your system is 64 bit.

I meant lm alone, which you have anyway (see the bold highlighting in your quote)..so you system is 64 bit.
A 32 bit OS would work anyway, you would just need some ia32 package for compatibility.

Please, when you post commands, outputs or similar, use the [CODE] tags, it makes the thread more easy to read.

a word of warning

SL6 has even LESS documentation than CentOS6 has
so you will need to be able to port the RHEL / CentOS and Fedora documentation for use in SL6

and by less i mean almost NONE .

He's right. Check and revert back your result in here.
