Well, AMD64 support as a tier-1 platform only came
in with 5.x, so
you're S.O.L. if you have to use a 4.x release
version.
Will a i386 disk boot on opteron system? Can I use same disk image for intel and amd MBs? Any big problems?
You can generally run AMD64 machines in IA32 mode

but what would be the point? All you get then is a machine that
costs
more than an equivalent IA32 box and that probably performs worse.
That is very curious to say. Isn't the advantage of Opteron the superior IO architecture? There is not much advantage with 64 bit computing. What is faster about it? Pointers are bigger, so it use more cache for less. NOt much 64bit math in OS. Why do you say it will perform worse?
Boris, I am sure you realize that a great deal of the 64 bit IO architecture is leveraged from the 64 bit instructions set, that allows things like 64 bit fetches. Will there be a gain without using the 64 bit instruction set? Yes. Will it be as large? No.
Boris
I am waiting for your answer.
