This does work on 32-bit i386 kernels (I checked). The kernel is just reporting the result of the cpuid instruction. It might not work if you kernel is really old, ie. it predates amd64 cpus. Paul

I don't want to know things about the system (the system in a x86 32bits Debian), but about the actual CPU in the machine. > The "lm" flag in /proc/cpuinfo tells you if the cpu is 64-bit (long mode) > capable.

How to recognize an Intel with EM64T extensions enabled?
Is there a way to figure, on a running system, if the processor features the EM64T extensions? In /proc/cpuinfo maybe? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
