If you have a AMD 64 chip with Fedora 64 bit OS are there compatibility 32bit issues

I am thinking of getting some AMD64 bit platforms since I've heard that they outperform any P4 platform. Is there any concern however that there could be any compatibility issues with any applications that are made to run on standard Red Hat 9 or 10?

That is, we have some applications that we've been using on Red Hat 9 & 10 and we want to make sure all of them will work on these new AMD64 platforms.

Thanks so much.

There should be no problem at all. Anything compiled for i386, 486, 586 or 686 should work just fine. (RedHat software is usually compiled for i386)

Incidentally, RedHat 10?

I've seen lockups on some machines, especially the e-machine amd64 laptops. To get it to boot properly, you'll need to disable pcmcia on those machines. This isn't an all encompassing problem, e-machines have all sorts of problems, even with XP64. I haven't nailed this down yet, it's something I just ran into a couple days ago, and it's a friend's machine.

Fedora locked up tight right at the keyboard selection stage, so we tossed in Knoppix (thanks Mr. Knopper!), and it locked up at the pcmcia autodetect. Just for gits and shiggles , I disabled pcmcia (which unfortunately disables the networking on that laptop), and it booted like a charm. Of course, no networking is no fun, but if it's your system and you're familiar with Linux, you should be able to work on it from there. If it's a desktop or server, my guess is you're good to go.
