I have Centos 4.4 i386 installed an on i686. I tried making a mini-test live cd based on this install that just starts bash but it only works on i686 machines and not i586. I only have i386 glibc and all other packages are i386. I copied all of the necessary .so files. I even manually compiled bash using -march=i386 & -mtune=i386 but it will only run on i686. Can anyone explain why? Thanks!
