64-bit for redhat EL, please give advice

[Bliss, Aaron]

To install 64 bit redhat es, I didn't do anything special (no hardware
changes or anything), just booted to 64 bit install disk.

Learn something new every day...

So since we're on a Linux list, which cpu flags tell you that it's the
64-bit CPU in there?  I know we've got a bunch of recent DL380 systems
installed and I'm wondering if they should have the 64-bit distros
installed.

We're buying the new DL385 systems now.  You're right - they fly.  Even
for Windows :-)
