 4) Load the second kernel to be booted using:

    Note: i) <second-kernel> has to be a vmlinux image. bzImage will not work,
            as of now.
-       ii) By default ELF headers are stored in ELF32 format (for i386). This
-           is sufficient to represent the physical memory up to 4GB. To store
-           headers in ELF64 format, specifiy "--elf64-core-headers" on the
-           kexec command line additionally.
+       ii) By default ELF headers are stored in ELF64 format. Option
+           --elf32-core-headers forces generation of ELF32 headers. gdb can
+           not open ELF64 headers on 32 bit systems. So creating ELF32
+           headers can come handy for users who have got non-PAE systems and
+           hence have memory less than 4GB.
        iii) Specify "irqpoll" as command line parameter. This reduces driver
             initialization failures in second kernel due to shared interrupts.
