I take it the AMD is 1.4 GHZ P4 look alike? Check the kernel rev's in /boot before you do anything. IT IS highly likely that you will have to replace everything that is architecture specific not JUST /boot and the OS images..... - /lib/ , /usr/lib/, and rebuild everything. Any shared libraries that use specific P4 level instructions will cause the attached executable to core dump or the processor to hang (Illegal Instruction Error - core dumps user level stuff, hangs the kernel.) when it tries to run that section of code on your P3 architecture. You might be able to stuff the i386 stuff onto the drive to replace what is there to get an operational system and then do a full upgrade to put the righht libraries etc in place. Back things up FIRST, You may be better off running an Upgrade from the install cdrom's to make sure you get everything correct.... or just do a clean install. Depends how much you have invested in the configuration of the software and whether or not you can just copy off what you changed and reinstall it after a fresh install of Linux.
My recommendation would be to copy off, install fresh, and then put back your applications since that may be easier and safer in the long run. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of James Pifer > Sent: Thursday, September 04, 2003 3:36 PM > To: RedHat List > Subject: RE: Swapped Hard Drives > > > Yeah, you're probably on the right track.
