RE: 32bit OS on 64Bit Hardware...

["Frank, Ryan W" <ryan.w.frank@xxxxxxxxxxxxxxxxx>]

That did it!  The .i686 kernel instead of the athlon version fixed it :)
whooo hoo... Thanks again for your help!  It is much appreciated!

As I had an idea it was PAE related (in my google research) how would
one be able to tell if the running kernel supports PAE?  Also how did
you know I was running the athlon kernel not the i686... I am guessing
the timestamp?

Working:
Linux cltrsklccs01 2.4.21-40.ELsmp #1 SMP Thu Feb 2 22:22:39 EST 2006
i686 athlon i386 GNU/Linux

Non-working:
Linux cltrsklccs01 2.4.21-40.ELsmp #1 SMP Thu Feb 2 22:14:12 EST 2006
i686 athlon i386 GNU/Linux

Rpm -q -i didn't even show the version...

ah ha! 

in RHEL3, the "athlon" smp kernel is not PAE enabled, only the "i686"
smp kernel is.... and you're using the athlon kernel afaics.

so what you'd need to do is rpm -e of your existing kernel-smp, and grab
the i686 variant instead of the athlon one and install that...


(so this one extra line has been very useful in diagnosing this :)
