I have redhat linux installed on a hp box .

Can anyone please help me for how to check whether the hardware is 64bit or 32bit

Generally speaking, if you have to ask, then it is 32 bit. You usually wouldn't have 64 bit hardware unless you specifically went after it.

But it should say somewhere on the front of the case. OEMs love to plaster their cases with stickers that scream out all the vital specs of the machine. If all else fails, a simple Google search of the computer's model number should net you a rundown of it's base configuration and available options.

hi,

do

Code:

cat /proc/cpuinfo

in a terminal, and look for the lm flag ("cat /proc/cpuinfo | grep lm" is even easier). I order to check your distro, run uname -a. Finally, the ultimate test is to try and boot an 64bit LiveCD.

Ah! I found this in a configure script. It tells you if you have a 64 bit operating system or not.

Code:

uname -p

The older computer are all 32 bit version the new computers are 64 bits even dual core . The 32 bits software runs on 64 bits computer

all the best

Installed redhat version is RHEL ES 3.

I want to check whether my processor is 32bit or 64bit? not my Operating system?

cat /proc/cpuinfo gives you info about your processor, which will be the same regardless of the system. If you find the lm flag, you CPU supports 64bit instructions; if not, then it doesn't.
