----"How to understand if my kernel source is RedHat  i386 or i686. Is there
a shoert way of undersatnding it...?"
 
Best regards..

No, uname -a will tell you the type of processor fitted in your machine.   It 
will not tell you which processor your kernel was compiled for.

eg you can compile a kernel for a 386 so it runs on anything, install it on 
an AMD Athlon, and uname -a will tell you it's an i686.

The kernel source is not specific to a processor (it's not even specific to 
Intel x86 processors - it covers PPC, Alpha, MIPS..... as well).

The thing which is specific to the processor family is in 
/usr/src/linux/.config - look for the lines starting with CONFIG_M386 and 
going through to CONFIG_MCYRIXIII.

The one which says =y at the end is the one your kernel will compile for.
