Redhat Advanced Server 3 64 bit mode

It ought to be simple - but alas...

I am trying to figure out how to get redhat AS 3 to run in 64 bit mode on an AMD64 machine. I have installed OS, but it seems to be all 32 bit. The kernels in /boot, all the system SW etc is 32 bit. And I know it is possible to get all things in 64 bit, since I have access to an identical server that is full of 64 bit programs (including the kernel images).

Am I supposed to get a special 64 bit version? But where? It doesn't appear to be for sale on Redhat's site.

yes, it requires a 64-bit-specific installation cd/iso to install a 64-bit version of red hat. i see rhel3 as/es x86_64 isos on the rhn for download, although it is entirely possible that you have to contact a rh rep to purchase these.

As long as your subscription is current, you ought to be able to see it on RHN. Go to and login, then go to "Channels" on the top bar, and then, on the left, there is a button that says "All" (Subset of "Software Channels") Click on that, and it will bring up all channels. Scroll down until you find the channel for the 64-bit ( Most likely "Red Hat Application Server 3.0 (AS for ia64)" or something like that) and you should be able to D/L the ISO's from there. Happy hunting.
