To run 64 bit installs of linux, do I need 64 bit hardware? I tried to install on a Xeon machine and it objected that the hardware was only 32 bit. (It's a 32 bit machine for the same reason I drive a Chrysler. All I could afford at the time :) ).<br>

To be sure, run this command from a bootable CD and see if it returns back something:<br>
<br>
# grep -w lm /proc/cpuinfo<br><br>
lm stands for long mode.<br>

In the same vein, if I install a 32 bit install of say Mandriva on a machine with 8 gigs of ram, would one expect that the kernel being installed will address all 8 gigs? </blockquote><div><br>No. Unless you have the bigmem patch.<br>
