dual boot, i386 or i686


redhat - 9.

Q.1. how do i know about my cpu type whether its i386 or i686 or i586. i use intel 865 GBF desktop board and p4 3GHz processor. Is there any command on linux to know this ??? actually the rpm which i download from internet r very specific to i386 or i686. is there any GUi tool where it will be displayed whether its a i386 or i686. can i install an rpm meant for i386 on an i686 system ?? suppose i have i686. can i download the iso image of fedora meant for i386 ? can anyone guide ???

Q.2. At booting , the following message appears.
GRUB version 0.93 (639k lower/1030335k upper memory)

Redhat linux (2.4.20-8smp)
Redhat linux-up (2.4.20-8)


why above 2 options r coming ??? earlier only one option use to appear. This time when i installed, 2 options r appearing . I have installed redhat 9. is there any difference between these 2 ?


thanx

you can use i386 packages on a i686 (which is what you have, the 686), but you cannot install i686 on a i386.

The reason why you have two kernel options in grub is because you have two kernels installed. It seem like you have an "smp" kernel (a kernel for computers with more than 1 processor) installed as well as an ordinary kernel. I don't think you need the smp kernel, so you can uninstall it.

A Pentium 4 is an i786 or 80786. Though this processor model is backwards compatible down to i386 or 80386, but Intel processors perform bad if the code was compiled for an older model. AMD processors do not lose performance if the code was compiled for an older model processor.
